Abstract

PURPOSE:To prevent chattering and permit certain starting by connecting a vacuum closed type thermo-contact usually in closed state having the bimetal whcih performs reverse operation due to the self-springiness between a pair of auxiliary filaments for starting. CONSTITUTION:A luminous bulb 2 is arranged in an outside bulb 1, and the main electrodes 3 and 4 of the bulb 2 are connected with a stabilizer 12 and the auxiliary filaments 5 and 6 for starting, and between the filaments 5 and 6, a vacuum closed type thermo-contact 7 usually in closed state is connected. In the glass tube 9 of the usually-closed contact 7, a lead wire 11 having a contact 13 and a lead wire 12 connected with a heater 14 are stored, and a supporting wire 15 has a contact 18, and at the center part, a bimetal 16 which has the concaved part 10 and operates reversely and springily is arranged. Therefore, chattering of the usually-closed contact 7 can be eliminated, and the breakdown of insulation of the instruments due to high voltage in restarting can be prevented certainly.
