ABSTRACT:
In a thermal cut-out for a heating means, e.g. a glass ceramic cooking unit, a signal switch and a circuit breaker are operated by means of a temperature sensor via a transfer member externally surrounding the switches and whereof the actuating member thereof located further from the temperature sensor is formed by an adjusting member, so that with the latter and also an adjusting member directly associated with the temperature sensor, a very precise setting is made possible. The transfer member is suspended in contact-free manner between oppositely acting springs and is therefore mounted in a substantially frictionless manner.
