General Description:ASCO P-Series pressure switches consist of an openframe or enclosure protected switch unit and atransducer unit. They can be ordered separately for cus-tomer stocking and/or field assembly or as acomplete factory-assembled unit.
SwitchP-Series pressure switch units incorporate the uniqueASCO TRI-POINT alternating fulcrum balance plate tocontrol the operation of one or more electrical snap-action swtiches. The electrical snap-action switchtogether with the adjusting mechanism is a fully-tested,self-contained subassembly.
TransducerTransducer unit incorporates a diaphragm/piston type pressure sensor, and is also a fully-tested, self-contained subassembly.
OperationWhen pressure is applied to the transducer it is converted into movement of the piston. This pistonmovement is then used to control the operation of the electrical snap-action switch in the switch unit.

Features:• Set point repeatability, +1% of operating range.• All wiring terminals, adjustments and visual scales are
accessible from the front of the switch.• Choice of general purpose, watertight or explosion-
proof enclosures.• Choice of fixed or full-range adjustable deadband.• Choice of single or two-stage units.• Manual reset units available.• Mounts in any position.• Rugged and vibration resistant.• Visual adjustment scales in psi and bars.• External adjusting nuts.• Separate electrical, pressure and adjusting
chambers.• Wide selection of transducer wetted materials suitable for air, water, oil or corrosive fluids.• Mix and match switch and transducer components for
increased stock flexibility or to change pressure ranges in field.
General Description:ASCO S-Series pressure switches consist of a switchunit and a transducer unit. They can be ordered separately for customer stocking and/or field assemblyor as a complete factory-assembled unit.
SwitchS-Series pressure switch units incorporate the uniqueASCO TRI-POINT alternating fulcrum balance plate tocontrol the operation of one or more electrical snap-action swtiches. The electrical snap-action switchtogether with the adjusting mechanism is a fully-tested,self-contained subassembly.
TransducerTransducer unit incorporates a diaphragm/piston type pressure sensor, and is also a fully-tested, self-contained subassembly.
OperationWhen pressure is applied to the transducer it is converted into movement of the piston. This pistonmovement is then used to control the operation of the electrical snap-action switch in the switch unit.

EnclosuresASCO TRI-POINT S-Series switches are available inthree standard enclosures. All of these enclosed unitsare made in accordance with NEMA and UL standards.
General Purpose – Type 1. These enclosures aredesigned for indoor use to protect personnel fromaccidental contact with the equipment. S-Series general purpose switch units consist of a copper-free*aluminum die-cast body with a formed copper-free* aluminum cover; two 3/4” conduit hubs with one plugare provided.
Watertight – Type 4. Watertight and dust-tight enclo-sures are intended for use indoors and outdoors to protect the enclosed equipment against splashing orfalling water, windblown dust and water, hose directedwater, and severe external condensation. S-Serieswatertight switch units have a copper-free* aluminumdie-cast body and a formed copper-free* aluminumcover with Buna “N” gaskets; two 3/4” conduit hubs with one plug are provided.
Explosion-Proof – Types 7 and 9. Type 7 enclosuresare intended for use in locations defined by the NationalElectrical Code as Class I. Type 9 enclosures areintended for Class II locations.
Class I locations are those in which flammable gasesare or may be present in the air in sufficient quantitiesto produce explosive or ignitable mixtures. Class I loca-tions are classified by group letter, which defines partic-ular atmospheres. Division 1 locations are areas wherethe hazardous concentration exists continuously, inter-mittently or periodically under normal operating condi-tions. Division 2 locations are those where the haz-ardous vapors are present only in case of accidentalrupture or breakdown of equipment.
ASCO TRI-POINT explosion-proof enclosures with letter B, C or D in the fifth position are listed for Class I,Groups B, C, and D, Division 1. They are also suitablefor the less stringent Division 2 environment.
Class II locations are those which are hazardousbecause of the presence of combustible dust. All ASCO TRI-POINT explosion-proof enclosures are listed for Groups E, F, and G locations.
The switch body and cover are die-cast copper-free*aluminum with a Buna “N” gasket. Two 3/4” conduithubs with one plug are provided.

How to Select1. Select the adjustable operating range based on desired actuation pressure.2. Check that proof pressure is sufficient.3. Read across and select thedesired S-Series switch unit with the proper enclosure.4. Continue across and select a matching transducer unit compatible with the fluid.
How to OrderFactory assembled – Simplyorder the switch and transducerunit by catalog number joined by a slash (/), e.g., SA40D/TA40A11.Field assembled – Simply order the switch and transducerunits separately by individual catalog number, e.g., one SA40D and one TA40A11.
How to Select and OrderASCO S-Series switches consist of two components, the switch unit and the transducer unit.
Single-Stage Adjustable Deadbandunits allow independent adjustment ofthe set and resetpoints over the fulloperating range ofthe switch. Theminimum differencebetween set andreset points is thedeadband listedbelow; the maximumdifference is the fullrange of the switch .
SB Switch Unit: Single-Stage FixedDeadband units have an adjustable set pointand a non-adjustable automatic reset point.SD Switch Unit: Manual reset on decreasingpressure units operate automatically onincreasing pressure and must be reset manually on decreasing pressure.(To order, change second digit to letter “D”,e.g., S B 40D becomes S D 40D).SE Switch Unit: Manual reset on increasingpressure units operate automatically ondecreasing pressure and must be reset manually on increasing pressure.(To order, change second digit to letter “E”,e.g., S B 40D becomes S E 40D).

General Description:ASCO S-Series combustion switches consist of aswitch unit and a transducer unit. They can be orderedseparately for customer stocking and/or field assemblyor as a complete factory-assembled unit.
SwitchS-Series combustion switch units incorporate theunique ASCO TRI-POINT alternating fulcrum balanceplate to control the operation of one or more electricalsnap-action swtiches. The electrical snap-action switchtogether with the adjusting mechanism is a fully-tested,self-contained subassembly.
TransducerTransducer unit incorporates a diaphragm/piston type pressure sensor, and is also a fully-tested, self-contained subassembly.
OperationWhen pressure is applied to the transducer it is converted into movement of the piston. This pistonmovement is then used to control the operation of the electrical snap-action switch in the switch unit.

UL RequirementsUnderwriters’ Laboratories, Inc.’s Standard UL 353defines construction and performance requirements forlimit controls.
SwitchS-Series combustion switch units when mated to thepressure transducers described below form pressureswitches in accordance with UL requirements.
TransducersFuel Gas – UL requires a pressure transducer with asecondary chamber. This chamber allows the gas to be vented to a safe location in the event of primary sensing element rupture. The “double chamber” withvent pressure transducers meet this requirement.
Fuel Oil – UL requirements for fuel oil applications waive the double chamber requirement, providing thesensing element is made of Type 316 or 321 SS. S-Series type 316 SS pressure transducers aredesigned to meet this requirement.
General Service – Pressure transducers for water,steam and air service may be of the single chamberdesign.
EnclosuresASCO TRI-POINT S-Series switches are available inthree standard enclosures. All of these enclosed unitsare made in accordance with NEMA and UL standards.
General Purpose – Type 1. These enclosures aredesigned for indoor use to protect personnel fromaccidental contact with the equipment. S-Series general purpose switch units consist of a copper-free*aluminum die-cast body with a formed copper-free* aluminum cover; two 3/4” conduit hubs with one plugare provided.
Watertight – Type 4. Watertight and dust-tight enclo-sures are intended for use indoors and outdoors to protect the enclosed equipment against splashing orfalling water, windblown dust and water, hose directedwater, and severe external condensation. S-Serieswatertight switch units have a copper-free* aluminumdie-cast body and a formed copper-free* aluminumcover with Buna “N” gaskets; two 3/4” conduit hubs with one plug are provided.
Explosion-Proof – Types 7 and 9. Type 7 enclosuresare intended for use in locations defined by the NationalElectrical Code as Class I. Type 9 enclosures areintended for Class II locations.
Class I locations are those in which flammable gasesare or may be present in the air in sufficient quantitiesto produce explosive or ignitable mixtures. Class Ilocations are classified by group letter, which definesparticular atmospheres. Division 1 locations are areaswhere the hazardous concentration exists continuously,intermittently or periodically under normal operatingconditions. Division 2 locations are those where thehazardous vapors are present only in case of acciden-tal rupture or breakdown of equipment.
ASCO TRI-POINT explosion-proof enclosures with letter B, C or D in the fifth position are listed for Class I,Groups B, C, and D, Division 1. They are also suitablefor the less stringent Division 2 environment.
Class II locations are those which are hazardousbecause of the presence of combustible dust. All ASCO TRI-POINT explosion-proof enclosures are listed for Groups E, F, and G locations.
The switch body and cover are die-cast copper-free*aluminum with a Buna “N” gasket. Two 3/4” conduithubs with one plug are provided.
FM RequirementsFuel Gas and Fuel Oil – FM requires that fuel gas and fuel oil pressure supervisory switches shall have avisible external means of determining switch position.No specific constructions are required for the pressuretransducer. Switch units with visual position indication(suffix “V”) in conjunction with single chamber pressuretransducers will meet these requirements.
General Service – Standard switch units with an adjusting nut cover, when mated to single chambertransducers, meet FM requirements for general applications such as “airflow interlocking switches”.
EnclosuresGeneral Purpose – Designed to Type 1 specificationsfor indoor applications. Die casting is copper-free* aluminum; covers are polycarbonate. Two 3/4” conduithubs with one plug are provided.
Watertight – Designed to Types 4 specifications forindoor/outdoor use. Die casting is copper-free* aluminum. Cover are polycarbonate and gaskets areneoprene. Two 3/4” conduit hubs with one plug are provided.
* Less than 0.6% copper.

S-SERIES Combustion Switches
How to Select1. Select the adjustable operating range based on desired actuation pressure.2. Check that proof pressure is sufficient.3. Read across and select thedesired S-Series switch unit with the proper enclosure.4. Continue across and select a matching transducer unit compatible with the fluid.
How to OrderFactory assembled – Simplyorder the switch and transducerunit by catalog number joined by a slash (/), e.g., SA30D/TA31A11.Field assembled – Simply order the switch and transducerunits separately by individual catalog number, e.g., one SA30D and one TA31A11.
How to Select and OrderASCO S-Series switches consist of two components, the switch unit and the transducer unit.
Single-Stage Adjustable Deadbandunits allow independentadjustment of the setand reset points overthe full operating rangeof the switch. Theminimum differencebetween set and resetpoints is the deadbandlisted below; themaximum differenceis the full range ofthe switch .
SB Switch Unit: Single-Stage FixedDeadband units have an adjustable setpoint and a non-adjustable automatic reset point.SD Switch Unit: Manual reset on decreas-ing pressure units operate automatically on increasing pressure and must be reset manually on decreasing pressure.(To order, change second digit to letter “D”,e.g., S B 30D becomes S D 30D).SE Switch Unit: Manual reset on increas-ing pressure units operate automaticallyon decreasing pressure and must be reset manually on increasing pressure.(To order, change second digit to letter “E”,e.g., S B 30D becomes S E 30D).

General Description:ASCO P-Series temperature switches consist of anopen frame or enclosure protected switch unit and atransducer unit. They can be ordered separately forcustomer stocking and/or field assembly or as a complete factory-assembled unit.
SwitchP-Series temperature switch units incorporate theunique ASCO TRI-POINT alternating fulcrum balanceplate to control the operation of one or more electricalsnap-action swtiches. The electrical snap-action switchtogether with the adjusting mechanism is a fully-tested,self-contained subassembly.
TransducerThe temperature transducer unit uses a vapor pressureprinciple where the internal pressure within the unit isgenerated by the vapor pressure of a chemical within asealed system. Temperature transducers are availablein two constructions, a direct mount or capillary andbulb construction. The direct mount unit includes a 1/2”NPT connection for direct mounting to the process. Thecapillary and bulb construction allows remote mountingfrom the process. The transducer unit (like the switchunit) is a fully-tested, self-contained subassembly.

These enclosed units aremade in accordance with NEMA and UL standards.These standards define the protection level an enclosure gives and the tests it must pass to meet a particular design.
General Purpose – Type 1. These enclosures aredesigned for indoor use to protect personnel fromaccidental contact with the equipment. P-Series general purpose enclosures are painted, zinc-coated
steel and have a 7/8” diameter hole at the top for electrical entry.
Watertight – Type 4. Watertight and dust-tight enclosures are intended for use indoors and outdoorsto protect the enclosed equipment against splashing orfalling water, windblown dust and water, hose directedwater, and severe external condensation. P-Serieswatertight switch enclosures are epoxy-painted, zinc-coated steel with a 1/2” conduit hub in the side of thelower housing for electrical entry. (For optional 316 SSwatertight enclosure see page 29.)

Transducer Unit
The temperature transducer works on the vapor principle wherethe internal pressure within the system is generated by the vaporpressure of a chemical within a sealed system. The temperaturesensed by the bulb is related uniquely to an internal pressurewithin the system. The pressure acts on a diaphragm/piston tocreate the force output from the transducer into the switch unit.Temperature transducers are available in two constructions. Thedirect mount (local) unit includes a 1/2” NPT connection fordirect application to the process. The capillary and bulb-typeconstruction allows for remote mounting from the process.

General Description:ASCO S-Series temperature switches consist of aswitch unit and a transducer unit. They can be ordered separately for customer stocking and/or field assemblyor as a complete factory-assembled unit.
SwitchS-Series temperature switch units incorporate theunique ASCO TRI-POINT alternating fulcrum balanceplate to control the operation of one or more electricalsnap-action swtiches. The electrical snap-action switchtogether with the adjusting mechanism is a fully-tested,self-contained subassembly.
TransducerThe temperature transducer unit uses a vapor pressureprinciple where the internal pressure within the unit isgenerated by the vapor pressure of a chemical within asealed system. Temperature transducers are availablein two constructions, a direct mount or capillary andbulb construction. The direct mount unit includes a 1/2”NPT connection for direct mounting to the process. Thecapillary and bulb construction allows remote mounting

EnclosuresASCO TRI-POINT S-Series switches are available inthree standard enclosures. All of these enclosed unitsare made in accordance with NEMA and UL standards.
General Purpose – Type 1. These enclosures aredesigned for indoor use to protect personnel fromaccidental contact with the equipment. S-Series general purpose switch units consist of a copper-free*aluminum die-cast body with a formed copper-free* aluminum cover; two 3/4” conduit hubs with one plugare provided.
Watertight – Type 4. Watertight and dust-tight enclo-sures are intended for use indoors and outdoors to protect the enclosed equipment against splashing orfalling water, windblown dust and water, hose directedwater, and severe external condensation. S-Serieswatertight switch units have a copper-free* aluminumdie-cast body and a formed copper-free* aluminumcover with Buna “N” gaskets; two 3/4” conduit hubs with one plug are provided.
Explosion-Proof – Types 7 and 9. Type 7 enclosuresare intended for use in locations defined by the NationalElectrical Code as Class I. Type 9 enclosures areintended for Class II locations.
Class I locations are those in which flammable gasesare or may be present in the air in sufficient quantitiesto produce explosive or ignitable mixtures. Class Ilocations are classified by group letter, which definesparticular atmospheres. Division 1 locations are areaswhere the hazardous concentration exists continuously,intermittently or periodically under normal operatingconditions. Division 2 locations are those where thehazardous vapors are present only in case of acciden-tal rupture or breakdown of equipment.
ASCO TRI-POINT explosion-proof enclosures with letter B, C or D in the fifth position are listed for Class I,Groups B, C, and D, Division 1. They are also suitablefor the less stringent Division 2 environment.
Class II locations are those which are hazardousbecause of the presence of combustible dust. All ASCO TRI-POINT explosion-proof enclosures are listed for Groups E, F, and G locations.
The switch body and cover are die-cast copper-free*aluminum with a Buna “N” gasket. Two 3/4” conduithubs with one plug are provided.

Transducer Unit
The temperature transducer works on the vapor principle wherethe internal pressure within the system is generated by the vaporpressure of a chemical within a sealed system. The temperaturesensed by the bulb is related uniquely to an internal pressurewithin the system. The pressure acts on a diaphragm/piston tocreate the force output from the transducer into the switch unit.Temperature transducers are available in two constructions. Thedirect mount (local) unit includes a 1/2” NPT connection fordirect application to the process. The capillary and bulb-typeconstruction allows for remote mounting from the process.

Switch Unit – ASCO uses the term “switch unit” to describethe electromechanical portion of a pressure or temperatureswitch. This is used in conjunction with a transducer unit toform a complete pressure or temperature switch.
Transducer Unit – ASCO uses the term “transducer unit” todescribe that portion of a pressure or temperature switch towhich a pressure or temperature is applied which convertsthe input signal to another form of energy to operate theswitch unit.
Two-Stage (Dual) – ASCO uses the term “two stage” todescribe a pressure or temperature switch which is equivalentto two pressure or temperature switches which areindependently adjustable. This switch is equivalent to twofixed deadband switches.
Deadbands – The deadband is the difference between theset point and reset point readings. Deadbands are listedin the specification tables at nominal values. They are representative of the deadbands of the units at the middleof the range.
The deadband values for the full range adjustable deadbandswitches and limited adjustable deadband switches indicatethe values through which the deadband may be adjusted.
Generally, as the set point is adjusted through the operatingrange, the deadband will vary. Normally, it will becomenarrower as the set point is towards the bottom of the range,and will become wider when the set point is towards the topof the range. The graph shown below indicates representativetrends of this type of deadband variation.
Temperature switch deadbands are a result of the characteris-tics of the vapor pressure curve as well as other factors.Normally, this results in a deadband which is narrower in thetop third of the range than in the bottom third of the range.The values published are nominal and representative of mid-range set points.

Definitions and Fluid Compatibility Guide
Accuracy – The maximum deviation from the set pointunder specified operating condition (ambient temperature,barometric pressure, etc.).
Adjustable Deadband – Refers to the capability of apressure or temperature switch to allow the deadband to beadjusted over a given range. Certain ASCO TRI-POINTswitches have an adjustable deadband which can beadjusted over the total operating range of the switch.
Adjustable Operating Range – The pressure or tempera-ture range of the switch within which the set point may beadjusted.
Differential Pressure – The difference between twopressures. A differential pressure switch senses two pressuresources and can be adjusted to actuate on a desireddifference between them.
Guage Pressure – The actual reading of a typical pressureguage and is the difference between the pressure within avessel and the atmospheric pressure surrounding it. It isnormally measured in pounds per square inch (psig).
Manual Reset – The switch is a semi-automatic devicewhich operates automatically with a signal change in onedirection but must be manually reset once the signal returnsto its original position.
Proof Pressure – A pressure which a device can besubjected to for extended periods of time without changesin its operating characteristics.
Rated Overrange Temperature – A temperature which adevice can be subjected to for extended periods of timewithout changes in its operating characteristics.
Repeatability – The closeness of agreement among anumber of consecutive measurements of the output for thesame value of input under the same operating conditionsapproaching from the same direction. Repeatability isnormally specified as a percentage of the upper limit of theoperating range.
Example: Operating range 5-100 psig with +1%repeatability; equals +1% of 100 psig or +1 psig.
Reset Point – After a pressure or temperature switch hasreached its set point and operated the electrical switch, itmust return to a point called the reset point before theelectrical switch can return to its original position.
Set Point – The pressure reading at which the electricalswitch element changes contact position (it can be specifiedeither increasing or decreasing).
