CPI’s SnapStat line of bimetallic thermal switches have a bimetal snap disc that actuates a miniature microswitch. This double snap action makes these switches virtually immune to shock and vibration. Epoxy sealing or glass to metal hermetic sealing makes them ideal for demanding industrial or military applications.
