This is a Atlas Model Railroad HO-Gauge Code 100 Remote Left-Hand Switch Machine, and is intended for use with Code 100 Snap-Switches. Snap-on remote switch machines will quickly and easily convert any Atlas code 100 HO switch to remote control. With a remote control switch you can wire the switch to be "thrown" (changing the direction of the rail) from your control panel, rather than from the switch itself.
