Abstract (en)
[origin: EP0993015A2] The switching device has a rod-shaped temperature sensor (15) consisting of a tube (16) containing an elongate element (17) of differing thermal expansion coefficients. A switch (22) with a snap-action spring is actuated by the temperature sensor via a separate operating device which is formed integrally with the spring. The spring may be a compression spring.
