If you want to use AC, you can use 2 diodes and a DPST switch. Many like to use one with a center off position, even a "momentary" one so power isn't applied to the switch all the time. This is critical on your LGB units. On the Aristo units, it can help if something jams the throw so the internal limit switch doesn't turn off the motor. Since the motor draws very little current, any switch you find will do.



You can wire many switches to the same pair of diodes.
