OVERVIEW:
Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that “snaps” from a convex to a concave shape at a set temperature. When the disc “snaps”, it either completes or interrupts a circuit. The most common application for a snap switch or snap action thermostat is as an over-temperature protection (or OTP) failsafe.
