The toggle switch itself should operate as follows (well 99% of the time, I have found a few that are reversed). Moving the bat handle up, the middle terminal and the bottom terminal should be closed. Moving the bat handle down, the middle terminal and the top terminal should be closed.
I'm in the process of remodeling my HO control panel. Currently I'm using Atlas turnout switches and I want to change them to toggle switches. My problem is the Atlas switch actually has 5 wiring points (3 for switching - 2 for power), while the momentary spdt toggle switch only has 3 places to connect wiring and this is where I got lost. Does anyone know how to wire the momentary toggle switch?
