Notes:
1) Everything is running at 5v
2) This needs to be done on the cheap, there will be 100+ of these circuits on one project and I am trying to keep the price per part way low.
3) It is Arduino based, and I am already using shift registers to control a lot more outputs then I have access to.
Problem: Imagine multiple electric trains running along on their own circuits. They run over a physical switch that opens the circuit killing their motors. Later, I want to remotely close the circuit (all 100 of them) at the same time to allow the trains to run again. Now the fun part, some of these circuits will already be closed (IE some trains did not run during the last iteration).
Now the switch particulars, I would like it to be lever actuated, and on the pressing of the lever it opens the circuit. It can NOT be a momentary as the 5v power needs to be severed for a length of time to different circuits until an all go signal is sent.
My brain is trying to wrap around this and it basically seems to be a half relay half switch idea.
