I've attempted to incorporate a discharging RC circuit that will "unlatch" a solenoid when power is turned off. However, I'm not fully confident that I've correctly designed what I hope to achieve (little circuit design experience).
The solenoid plunger holds position in both extended and retracted positions. Only a brief 100ms of power is needed to move the plunger to either state. I am using two relays, in which the 'NC' terminal is wired to the direction of current which would retract the plunger inward. Therefore, when power is turned off, the RC would discharge and retract the plunger. I am looking for review and feedback on the correctness of my approach. Advice and suggestions are welcome.
