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.
Claims35
A thermal cut-out (1) for a heating means, said cut-out having a substantially rod-like temperature sensor (6) for operating a signal switch (4) and a power switch (5) arranged in a base (2) for switching off the heating means at a predetermined maximum temperature, said temperature sensor having an outer tube (7) and an inner rod (8) located therein, a transfer member (9) continuately arranged to a socket-side end of the inner rod (8) being provided for acting on actuating points (31, 37) of both switches (4, 5) by actuating members (30, 32), said switches (4, 5) being substantially arranged in a length extension of the inner rod (8), wherein at least one of the actuating members (32) is operatively connected to an adjusting device provided on the transfer member (9) for varying the relative spacing between the actuating members (30, 32).
