What is a snap switch also known as Snap Disc or snap action thermostat? Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that âsnapsâ from a convex to a concave shape at a set temperature. When the disc âsnapsâ, it either completes or interrupts a circuit.
