Wiring Peco AUXILIARY Switch

Attached to a Peco switch motor is an Auxiliary switch for track signal or lights on the control panel and maybe more.

The switch has a common feed post and two outlets. I wired the switch to a terminal strip and attached a positive feed from a power supply to the common feed post on the terminal strip.

Using a multimeter there is no circuit between the feed and the oulets.

I assumed the two oultets are for connection to a light, etc. but there evidenlty needs to be a ground wire but if you use one of the outlets then there aren’t two for a LED or bulb.

Help will be appreciated.

I suspect the Peco switch is a SPST switch. That means the center terminal will connect to one or the other of the outside terminals depending on which way the turnout it is attached to is thrown. For instance, positive wire to center terminal, one outside wire to a red LED, the other to a green LED and the remaining two LED leads to the negative of the power supply. Or, the center terminal to the frog of the turnout and the two outside terminals to the appropriate rails to power the frog with the correct polarity.

it should do, pop the thing apart and see what is going on inside. if you use N gauge points? the less throw of the tiebar sometimes doesn’t allow the switch enough travel to make a circuit. but this fault is only in one direction.

Problem SOLVED !

Running a ground wire to the LED and a second wire from the LED to an outlet from the auxiliary switch. Of course a positive wire goes to the common feed. The second oulet is live when the turnout is turned and the first in then dead.

Thanks for the replies.
