Wall-Mount Temperature Switches

Single Pole, Double Throw (SPDT) Switch with Enclosed Housing

Double Pole, Single
Throw (DPST) Switch
with Enclosed Housing

Turn heating equipment on or off at a specified temperature. Switches have a probe on a cable for remote temperature readings. Set the actuation point with the adjustment dial.

Switches that control one circuit are single pole, double throw (SPDT). They can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Switches that control two circuits are double pole, single throw (DPST). They turn two circuits from on to off (normally closed).

Switches with a pilot light indicate when the switch is on.

Use packing seals and fittings (sold separately) to seal the probe into threaded tanks and pipes.

Washdown Wall-Mount Temperature Switches

With
Threaded
Copper Probe

With Unthreaded
Stainless
Steel Probe

To protect these switches from splashing water, corrosive liquid, and dust, the housing meets NEMA 4X for washdown conditions. Switches turn heating equipment on or off at a specified temperature. All have a probe on a cable for remote temperature readings. Set actuation points with the adjustment dial.

Single pole, double throw (SPDT) switches can be set to turn circuits from off to on (normally open) or from on to off (normally closed). Switches with one actuation point have one single pole, double throw (SPDT) relay. The relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed). The probe has 1/2 NPT male threads for installation directly into tanks, pipelines, and other process components. It comes with a bushing that adapts the thread size to 3/4 NPT male. Switches with two actuation points have two single pole, double throw (SPDT) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Hazardous Location Wall-Mount Temperature Switches

With Threaded Probe

With Unthreaded Probe

Turn heating equipment on or off in environments with flammable gases and combustible dust, such as chemical plants, refineries, and grain elevators. The switch housing is UL listed for use in Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III hazardous locations. It also meets NEMA 4X for use in washdown environments with splashing water, corrosive liquid, and dust. Switches have a probe on a cable for remote temperature readings. Set actuation points with the adjustment dial.

Switch with one actuation point has one single pole, double throw (SPDT) relay. The relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed). The probe has 1/2 NPT male threads for installation directly into tanks, pipelines, and other process components. It comes with a bushing that adapts the thread size to 3/4 NPT male.

Switch with two actuation points has two single pole, double throw (SPDT) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Threaded Temperature Switches

Install the threaded probe directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature. These switches have an adjustment dial to set the actuation point. All are single pole, double throw (SPDT). They can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Compact Threaded Temperature Switches

NPT Male Threaded

NPT Male Ã— NPT Male Threaded

Since these switches don’t have a housing above the probe, they are often used in tight spaces and low-clearance areas. The threaded probe installs directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature. Use the adjustment screw to set the actuation point. All switches are single pole, single throw (SPST) and control one circuit.

Normally open switches turn the circuit from off to on.

Normally closed switches turn the circuit from on to off.
