Scr Circuit. The circuits use a variety of different methods to control the load current flow but all require the gate to be fired and the anode cathode voltage to be removed to stop the current flow. Scr testing circuit actuating the normally open on pushbutton switch connects the gate to the anode allowing current from the positive terminal of the battery through the load resistor through the switch through the cathode gate pn junction and back to the battery.
A fixed resistor works extremely well for r1. Scr tester circuit this useful little scr circuit can provide you with a visible indication is a one afternoon project and it is simple to put together. Thyristor scr circuits are widely used for power control of both dc and ac systems.
The circuit below shows the single phase half wave rectifier circuit using scr.
