Abstract

PURPOSE:To reduce the leaking current, by keeping current from flowing through a trigger circuit for a silicon controlled rectifier connected to both the terminals of a rectifier circuit when a series circuit consisting of a power supply circuit and the silicon controlled rectifier through a sensor circuit. CONSTITUTION:A transistor 24 is turned on or off by the action of the sensor circuit 1 such as a proximity switch to control the silicon controlled rectifier 22. A transistor 36 is coupled between a resistor 25 and the gate of the rectifier 22 and is turned on or off by the NC output of the sensor circuit 1. When the rectifier 22 is open, the transistor 36 is open and no current flows through the trigger circuit. Thus, the total leaking current is reduced. At the same time, the transistor 24 is closed and its gate and cathode are short-circuited. Therefore, the wrong operation of the silicon controlled rectifier 22 due to noises is prevented.
