Should you decide to use Ross switches, one of the easiest ways to control them is to use a Piko switch controller normally used with G scale trains. This Piko controller is specifically designed to operate up to four LGB switch motors like the ones used on Ross switches. You hookup either an AC or DC power source to its power input terminals and the controller automatically converts it to the precise DC power required to operate the LGB switch motors. It's surface-mounted and has a clean almost art-deco design.
