Patent ID: 8588629

Claim:
A thermally-actuated switch comprising: a housing; a displacement member that is held by the housing in a concave shape with respect to the outside of the housing and is displaced in a convex shape with respect to the outside of the housing in response to temperature changes; a first electrode that has a first contact provided inside the housing; a second electrode that has a second contact provided between the displacement member and the first contact and that is urged such that the second contact is separated from the first contact to the displacement member side; a movable member that is provided between the second electrode and the displacement member so as to be movable in a first direction directed from the second electrode side to the displacement member side, is pushed at one end by the displacement member in a concave state to push the second electrode at the other end to bring the second contact into contact with the first contact, and is moved in the first direction by an urging force acting on the second electrode due to convex displacement of the displacement member; and a regulating member that regulates movement of the movable member in a second direction orthogonal to the first direction from a transmittable position where a pushing force from the displacement member is capable of being transmitted to the second electrode, and releases the regulation such that the movable member moved in the first direction by the urging force is removed from the transmittable position.
