Claims

[Scope of utility model registration request]

A pair of flat bimetals each having one end fixed and the other free end, and a contact point that contacts each other formed at each other end, and a drive attached to one or both of the bimetals to make the bimetal respond thermally. and a case made of synthetic resin that houses the bimetal and the heater, and the bimetals are arranged side by side on the side of the case with the fixed edges of each of the bimetals on the same straight line and with appropriate spacing between the two bimetals. A thermally responsive switch, characterized in that a protrusion is provided on the inner surface of the case to abut on a portion of the bimetal that is remote from the contact and prevent the vicinity of the bimetallic contact from coming into contact with the inner surface of the case.
