A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops.

The motor controllers for large electric motors normally incorporate a type of circuit breaker known as a no-volt release. If the power fails, the circuit breaker opens and the motor will not restart when the power is restored. The circuit breaker must be reset before the motor can be started again.
Automatically closing the breaker after it has tripped and stayed open for a brief amount of time, usually after 1 to 5 seconds, is a standard procedure.
