I'm looking to create a circuit that has a single push button, that when pressed will cause a momentary pulse connection (12v) to a connected device, then on the next push, a -12v pulse, then +12, -12, etc etc.
It should not draw any power when "idle".
the device typically will draw 100mA when connected momentarily.
I have no real experience with creating circuits, but can follow and put together most diagrams.
I would guess i need some kind of latchine SPDT relay, connected to 2 DPDT relays... but how do i get the pulse (momentary) portion?
Diagrams/solutions very welcome!
Thank you,
