Slow make-break devices for immersion and flat surface temperature control applications that require close temperature control. Differential Expansion between internal struts and external shell provide fast response and close control.

THERMOSWITCH controllers control temperature as low as -100°F (-73°C) and as high as 600°F (316°C) with the proven dependability of over 75 years of service to satisfied customers. The THERMOSWITCH is a strut-and-tube type thermostat that operates on the principle of differential expansion between the outer shell and the inner strut assembly. As an unpowered mechanical temperature controller, the THERMOSWITCH has found wide acceptance in diverse applications requiring fast response, close control, extreme sensitivity and vibration resistance.
