Hello all!

I am obviously new here but a friend of mine and I are building a miniature M1-Abrams tank including a breach loading cannon and I'm trying to figure out how to wire the breach loading motor.

What I have is a 5amp 12V reversing motor. What I need to do is wire up a circuit whereby a single button push will move the motor from one travel limit to the other (i.e. the breach is normally closed, a single button push will open it fully, then close it fully).

I've been thinking I could use a latching DPDT relay but can't quite figure out how to set it up so that it would stop at fully closed and still be able to start again.

Any help would be greatly appreciated!
