Abstract

PURPOSE:To make discharging time short by inserting a zener diode in an electronic timer circuit then reducing the impedance at the OFF time of an electric power supply. CONSTITUTION:If a switch 2 is closed, a zener voltage of a zener diode 9 is applied to an electronic timer circuit 10. A relay coil 12 is driven by the output from the electronic timer circuit 10 and a contant voltage IC6. If the switch 2 is turned to OFF in this state, a voltage that has been charged starts to discharge through a route of resistors 8, 16 and a driver 18, and a route of the resister 16 and the driver 18. The discharge progresses and when the discharge voltage becomes not grater than the voltage of a zener diode 17, the output of the driver 18 turns to OFF and that of the driver 19 turns to ON, and since the discharge is carried out throught the route of the driver 19, the electronic timer l0 discharges instantaneously.
