Using miniature toggle switches for Block Control
I have a small concept layout that is used with a MTH DCS control system. Since I operate conventional as well as PS-2/3 engines I sometimes need to remove track power from sidings. I have a block control panel that uses miniature toggle switches to select a block. Each switch operates a 12 volt relay that conducts power to the track (block). I can also select a block using my TIU/AIU control system in the same way.
Since the toggle switches only conduct about 1/2 amp when operating the relay I can use 22 gauge wiring to the panel.
