Field effect tube time relay circuit 2
It is actually a JS-20 time relay circuit. Before switch
SA is closed,
relay KA tends to release state. After SA is closed, the circuit starts to delay. After a period of time, the thyristor is turned on and KA is closed.
Adjust the potentiometer RP to change the delay time.
