A temperature sensitive switch has openable and closable electric contacts, a two-position bimetallic element and a two-position bistable element, both coupled to the contacts. At a predetermined maximum temperature, the bimetallic element moves from a first position to a second position and thereby opens the contacts and also moves the bistable element from a first position into a second position. The bistable element, in its second position, maintains the contacts open independently from the position of the bimetallic element, until the bistable element is reset from its second position to its first position, and thus the contacts are closed, by an external (manual) resetting force.
