We have done this, though always where we were confident that something would slip before things would break or blue smoke would be released. We actually used something like this on our air cannon for a game early this football season, but we did have circuit breakers (a "Stinger" 4 circuit MAXI fuse block) and switched the motors with pushbutton automotive starter switches (which are difficult enough to operate that they serve as a built-in dead man switch). As light as our air cannon is this year, it would require a gifted act of sabotage or multiple failure modes worthy of Wiley Coyote or the stooges to stall our drive motors. Whether the switches would smoke or the breakers would trip first is probably a valid question.

Sure, all the time. Spike relay modules to switch automotive & PG motors on and off.
