 06 Oct 2008 6:14 Help with latching switch circuit? |
|
|
|
I'm working on a custom car and I need a switching circuit. I'm more mechanically minded than electical, so I've been unable to work it out myself. I'm hoping someone here would be willing to take a stab at it. Here's what I need:
- Constant +12V input.
- Two switched +12V outputs, A & B.
- One momentary contact pushbutton switch.
First push/release of the switch latches output A to +12V (B remains zero V). Second push switches output B to +12V only as long as the switch is held closed (output A remains +12V). Third push/release unlatches output A; circuit returns to original state.
I would prefer to accomplish this with discrete components and relays if possible. I'm sure it could be done with a digital logic circuit, but that's way beyond my capabilities.
Many thanks!
