Hi,
I have a 3 Lionel 148 Dwarf Signal that I would like to be controlled by an 022 switch. Looking at the manual for the 148, it states that this can be done with an 0-72 switch (6-65165 and 6-65166). Is it possible to do this with the 022? Or does anyone know if the signal will only work with a track contactor ?
If I wire the Dwarf Signal to the 022 screw terminals, both lights light up and stay lit, not matter what the 022 does. FWIW, I am using constant accessory voltage to the 022.
Thanks.

You can wire the signal successfully to the O22 switches. The center post of the switch machine is the common, the out post light one color or the other. On the base of the 148, the center screw terminal is RED, green to the right, and common to the left.
Having both colors illuminate at the same time makes me think you have your common in the wrong place.
You're going to get the same results from a O-72 switch. They are the same electrically.
Are these the modern LED versions?
This is an older pin-bulb one.
I tried rewiring, but same issue - on the 022, both outside posts seem to have power regardless of the switch setting, so both bulbs are lit. If it makes a difference, I have two 022 switches connected to each other (just via the outside posts) so that throwing the switch controls both switches.
Try one bulb at a time - common to the center post of the 022, one lead to one of the other posts. Does the one bulb stay on all the time?
Went back and tested it just now (double checked the wiring and made sure I had the ground right) and its working perfectly (not sure what I did wrong the first time) - thanks so much for all your help!

That's a common error on the 148, 163, & 363 signals as the common is the side post, not the center.
