Designed for use in rigorous industrial or laboratory condition to control overheating of air compressors, distilling machines, and other equipment. A bimetal snap disc reverses from convex to concave upon reaching temperature trip point, which activates a SPDT microswitch.
The three-wire design allows you to wire SPDT switch for either normally open (NO) or normally closed (NC) operation. Simple to install—switches require very little wiring and don't need shock mounts. Compact enough to easily thread into any 1/2" NPT opening. Stainless steel housing.
