When the disc “snaps”, it either completes or interrupts a circuit. Snap Disc thermostats have many practical applications. They are used to ensure the process temperatures do not exceed the thermal limits of the equipment or process. The most common application for a snap switch or snap action thermostat is as an over-temperature protection (or OTP) failsafe.Because of their small size and low mass, the response time of the snap switch design is extremely rapid compared to other commercially available thermostatic devices. Additionally, the bimetal element of a Snap Disc does not carry the current, but acts as the force to open and close the contacts. Thus snap action thermostats have a long life at relatively high currents – up to 16 amps for the ½ inch series – making snap switches the first choice of many OEMs.Stemco 402 Series Automatic Snap-disc Autou Reset Thermostat.Thermal Cutoff.
