Abstract
Thermal switch having a thermal bimetallic snap-over disc temperature sensor which interacts via a transmission component with a contact system which has at least one contact carrier carrying or forming a movable contact, the movable contact resting against at least one fixed contact in the quiescent state. In order to ensure that the switch remains in the non-quiescent open position after the thermal sensor has been tripped, provision is made that the movable contact is formed by a wire-type or strip-type contact part which can be plastically deformed by the transmission component actuated by the thermal bimetallic snap-over disc temperature sensor.
