The Caloritech™ Series 20000 Snap Acting Thermoswitch® temperature control system provides control action through expandable liquid acting in a bellows assembly. The bellows motion created by volume changes of this liquid activates a snap acting switch through a push rod. They are available in five models (pictured above), each applicable to a different temperature range.
