Yeah, it is a little extensive, aint it?
I figure I would get a good portion of the bugs out with this thread and then make the real deal and start a new post.
One of the last things standing in my way is the A/B switch. I'm concerned that the break-before-make operation of most switches will cause it to just disconnect and go defunct. Make-before-break isn't an option; this would short the battery out. Can't have that.
I dug around a bit and then it hit me - a set of mercury switches, all set to go off in tandem. But where are they? I know that there has been a lot of environmental concerns lately, but sometimes they just do the job better! Even surplus, they are very difficult to locate. 2 hours of probing Google got me almost nowhere. It's a shame that this is an all-or-nothing world we live in.
I figure setting it up so that the switches are on a pivot, and a finger hangs down below and hits the stops, causing the assembly to rock the other way, triggering the reversal.
Guess I better give that idea up, unless someone knows where to get them... back to the drawing board...
