Abstract
PURPOSE: To let a heat sensing thyristor go OFF even with a DC circuit by series- connecting the heat-sensing thyristor, a switching element which is turned ON and OFF by the output of a driving circuit and a load to a DC electric power source.
CONSTITUTION: A heat-sensing thyristor 3 which switches by detecting temperature, an NPN transistor 6 which is turned ON and OFF by the output of a driving circuit 7 and a load 2 are connected in series to a DC electric power source 1. When the temperature rises to the specified temperature or over, the heat-sensing thyristor 3 goes ON and the electric power is supplied to the load 2 by the ON-OFF condition of the NPN transistor 6. Thence, when the temperature lowers to the switching temperature of the heat-sensing thyristor 3 or less, the heat-sensing thyristor 3 is again turned OFF by the ON-OFF of the NPN transistor 6 and no electric power is supplied to the load 2. In this way, the heat-sensing thyristor may be turned OFF even with the DC circuit.
