Abstract: A thermostatic switch comprising a thermal snap-action element which is constraining, and in electrical contact with a spring element. On overheating, the thermal element snaps away from, and releases, the spring element, thereby breaking the electrical circuit. The released or unstrained position of the spring element is spaced from the thermal element in order to prevent electrical contact when the latter returns to its normal position.
