Yes. The OTC Controller is an on/off switch. Nothing special. Better off wiring them direct to their switch. If you plan to use the OTC, go to the GG site and it will show the wiring diagram. Be aware there are two versions off the 108 model - one has a two button controller and one has a three button controller - pre and post 2004 production. The pre 2004 has a magnet which is a bit high and effects running trains over it. Some people have shaved them down.
