Abstract
A thermally actuated switching device is disclosed that comprises a fixed contact placed on a proper member, a thermally actuated member such as a bimetallic member in the center of which is formed of a thin dish shape which contributes to a snap-action caused by heating of the bimetallic member, a bracket keeping the thermally actuated member in the concave-formed condition, a movable contact, which contacts on or removes from the fixed contact and is secured on the free end of the thermally actuated member, and a heat-resistant arc shield cantileverly held on the free end of the thermally actuated member or on a proper supporting member against the movable contact mounted surface of the thermally actuated member, so that the arc shield protects the thermally actuated member from an arc being introduced to it and prevents the deviation of the operation temperature of the thermally actuated member at the open or close action.
