Claims

[Claims for Utility Model Registration] 1. A fixed contact 1, a movable switch piece 2 that is placed facing the fixed contact 1 and is normally in contact with the fixed contact 1, and an upper surface that is placed facing the fixed contact 1. a thermal conductor 3 in which an opening-shaped recess 12 is formed;
A bimetal 4 is installed in the recess 12 of the thermal conductor 3, and is formed in a curved shape in whole or in part, and rotates rapidly when the temperature exceeds a predetermined temperature.The rapid rolling operation of the bimetal 4 presses the movable switch piece 2. and a pressing rod 5 for separating the movable switch piece 2 from the fixed contact 1. 2. A movable switch piece 2 is disposed facing the fixed contact 1, and a thermal conductor 3 having a recess 12 with an open top surface is disposed facing the movable switch piece 2, and the recess 12 of the thermal conductor 3 is disposed facing the movable switch piece 2. is equipped with a bimetal 4 which is entirely or partially formed into a curved shape and which rotates rapidly when the temperature exceeds a predetermined temperature, and which normally urges the movable switch piece 2 to abut against the fixed contact 1. Moreover, a biasing body 13 for releasing this contact state due to a sudden rolling action of the bimetal 4 is connected to the bimetal 4 and the movable switch piece 2.
A thermally responsive switch characterized by being provided between.
