Thermal Switch

Our bimetal thermal switch is a temperature sensing device which is made with a formed 1/2″ or 3/4″ bi-metal disc that “snaps” at a preset temperature, -21-450°F. Senasys’ snap disc thermostats are available as an automatic reset, manual reset or single shot operation. The thermal switches are used in equipment to open or close a circuit when temperature rises. A wide range of temperature settings, tolerances and differentials available. A wide variety of terminals and mounting options available.

Senasys designs and manufactures a wide range of thermal switches including bimetal snap action, fluid filled capillary style, and a digital style thermostat switch. Available as a fixed temperature or adjustable temperature solution, our thermostat switches range from sensing -50-700°F.

Our switches are made in the USA, 100% tested before leaving the factory and sold all over the globe.

We offer a variety of mounting options, terminals, and other custom configurations.
