I’m looking to build a circuit to control a 3V latching solenoid valve. This type of valve will open when a 30ms pulse passes through the solenoid and will remain open without consuming any energy until an oppositely charged 30ms pulse passes through the solenoid.
To further explain how it operates, the solenoid has two wires, red and black. Connecting the positive pole of 2 AA batteries to the red wire and the negative to the black wire will open the valve. On the other hand, connecting the negative to the red wire and positive to the black wire will close the valve.
I want to control the valve using a push button. As long as I keep the button pressed, the solenoid will remain open. When I let go of the button, the solenoid will close.
Also need the circuit to consume the least amount of energy as it will only operate with 2 AA batteries.
This could be activated with either: 1) a 2 pin push button (normally open) or 2) a 3 pin push button (1 NO + 1 NC)… whichever makes it easier to accomplish what is needed.
Thanks for your help!
