Barge Unloading Facility Build

[wheelie]

I do not think you can do it with your SPST switches at least without adding some relays..
You can get momentary DPDT switches in push button, toggle or rocker....
The biggest problem I can see with Push Button DPDT switch is when you pull your barge one way and stop... then you want to pull a bit more the same direction the push button switch is going to auto reverse so you would have to do 2 pushes to continue your original direction.. Toggle or Rocker are direction specific.. toggle or rock the direction you want to go..

Momentary switches auto return to off...
