Abstract

PURPOSE:To simplify and make small the circuit in size and to increase the working efficiency, by detecting the chattering through the output of the operational amplifier. CONSTITUTION:The circuit consists of the operation circuit 14 taking the pulse to start the relay and operated after the relay operation time from the pulse applied, operation circuit 15 discriminating the relay switching, operation circuit 16 comparing the output of the both operation circuits and holding the input of itself to a given lower voltage if chattering is taken place, and the operation circuit 17 turning off the output when the input and output of the circuit 16 is less than the specified value. Further, when the output of the circuit 16 is decreased at the occurrence of chattering and the input is a given voltage less than the specified voltage, the output of the circuit 17 is OFF and the chattering is detected. Accordingly, with a simple and low cost circuit, sure propriety judgement output can be obtained.
