This is a simple Electric Dc static Switch Circuit Diagram. This circuit
is a static SCR switch for use in a dc circuit. When a low power signal
is applied to the gate of SCR1, this SCR is triggered and voltage is
applied to the load. The right hand plate of C charges positively with
respect to the left hand plate through Rl. When SCR2 is triggered on,
capacitor C is connected across SCR1, so that this SCR is momentarily
reverse biased between anode and cathode. This reverse voltage turns
SCR1 off provided the gate signal is not applied simultaneously to both
gates. The current through the load will decrease to zero in an
exponential fashion as C becomes charged.
