Wiring the SC-2 to O Gauge and O-27 Switches

Making the connections between the SC-2 switch controller and your O Gauge or O-27 switches couldn’t be any easier. First, although you can run your switches off of track power as they are shipped, we highly recommend converting to a constant voltage of 14 Volts AC from an accessory power supply. This will extend the life of your switch by protecting it from the constant 18 Volts of command control on the rails and improve your operations as well whether you run with command control or conventional.

Wiring

SC-2

The SC-2 can control up to six switches from many manufacturers.

The SC-2 has its own external power supply. This simply plugs into the back of the base and attaches to a standard wall outlet. Also, unlike the ASC, you don’t need any wire connection directly to the command base.

To wire traditional switches to the SC-2, simply connect three wires from each of the six switch outputs to the terminals on your switch:

  1. Ground
  2. Through
  3. Out

We recommend color coding these wires to make tracing much easier. Any colors will do, just be consistent between switches. The Through and Out positions may not be marked on your switch. No problem – just guess!  If you’re wrong, the switch will simply through to the diverging route on “Through” and vice versa. To remedy this, simply switch those two wires on your switch connections.

Operating Your Switch

Using your TMCC or LEGACY remote, to operate the switch, simply press:

  1. Switch
  2. The Switch Number (1-99)
  3. Aux 1 (Through) or Aux 2 (Out)

That’s it! Now you have remote control of your switches from the palm of your hands. To see it all first hand, just check out this video:
