Abstract

PURPOSE:To prevent the occurrence of the burning of a stabilizer by the hot-adhesion of a thermosensitive element by burning off a heater when the thermosensitive element is hot-bonded. CONSTITUTION:When hot-adhesion occurs between the movable contact 14a and the fixed contact of the bimetal 8a, the connection between the movable contact 14b and the fixed contact 13b is opened by the operation of the bimetal 8b after a given period of time thereafter and then a great current dividedly flowing in the heaters 20a and 20b is all directed to the heater 20a whereby the heater 20a is burned off, the bimetal 8b is closed to connect the movable contact 14b with the fixed contact 13b, a great current flows in the heater 20b to burn off the heater 20b, and consequently the circuit for the auxiliary electrode 5 and the stem lead 10b becomes disconnected state, thus preventing the burning of the stabilizer.
