Abstract

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