    2 Circuits Controlled—Switches that control two circuits are double pole, single throw (DPST). They turn two circuits from on to off (normally closed).
    Open Housing—Switches with an open housing are often added to existing enclosures or custom installations.

    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.
    SPDT—SPDT (Single pole, double throw) 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 SPDT (single pole, double throw) 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 SPDT (single pole, double throw) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).
    DPST—DPST (Double pole, single throw) switch turns two circuits from on to off (normally closed).
    3PST—3PST (Triple pole, single throw) switches turn three circuits from on to off (normally closed).

    Turn heating equipment on or off in environments with flammable gases, combustible dust, and ignitable fibers, 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, Divisions 1 and 2 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.
