You could go buy a 'latching' relay...Basically, I have a 9 volt latching solenoid valve that i want to attach to "something" with a on off push button. I tested the valve by connecting the wires to the terminals of a 9 volt battery. It works fine, but I have to "flip flop" the connections in order to make the valve turn on and off.
Not really. You misunderstand.Thanks to all for your help. I think the momentary 2 pole switch will work just fine for my needs. This forum is awesome!
Case Closed
My presumption is that a latching solenoid is like a latching relay in that power is only required to change the state, but not to maintain it.
it could have 1 coil where the polarity is reversed, or 2 coils.
in either case a momentary double pole double throw switch with a centre off will do the trick. the disadvantages are that the final switch position will not indicate the solenoid state (which it sounds like you don't need) and you need a different action to turn it on vs. off (which may be an advantage or a disadvantage)
knowing how to wire it... well we need more details on the solenoid
Perhaps an R/c tx rx from China with a receiver controlled on off switch.
Many ways to achieve what you want but the advantage using the above is there is no building or programming to do.
