Well that would be tactile, or sound...probably. And it would have to be there whenever you wanted it. So if sound, then some way to poll it like pushing a button to cause one of two tones to sound. Tactile could be position or heat. Position seems more immediate to recent change, but heat is easier...two bulbs, dimly lit, enough heat to feel. Something like that. Just throwing out some maybe not great ideas but enough to get the thinking going.
There is another simple one, a toggle that’s not momentary. The switching of the toggle would just put out a momentary pulse instead of a constant connection to black wire. But wait, doesn’t the Fastrack circuit ignore the remote toggle once the switch is thrown? As long as the limit switches are doing their job? Then why does the toggle have to be momentary? The obvious fault with this is that there is no feedback from the Fastrack switch...ie, if the switch doesn’t throw, one would not know.
Anyway some ideas...
