Abstract

PURPOSE:To stabilize a delay switching circuit and to improve the reset operation of a relay by connecting a capacitor of small capacity in parallel to the delay switching and by connecting a high resistance between this circuit and capacitor. CONSTITUTION:An Ac power supply is connected to terminals 01 and 02, and rectifier diode 34, resistances 38 and 39, and delay switching circuit 31 are connected in series. Switching circuit 35 is provided which controls the power supply to relay coil 32 on the basis of the output of this circuit 31, and capacitor 37 is connected in parallel to coil 32 in order to replenish the power supply of relay coil 32. To stabilize the voltage of circuit 31, capacitor 36 of small capacity is connected in parallel to circuit 31 and high resistance 39 is interposed between this circuit 31 and capacitor 36. Consequently, the operation of circuit 31 is stabilized and the reset operation of relay 32 can be improved.
