Repairing a Lionel 022 switch

On the original 022 switches the track power is supplied to the solenoid through the track, and the constant voltage plug area can give you trouble if the copper contact doesn't seat 100% against the little pin inside. The constant voltage plug can be checked by using an alligator clip to hold it closed against the little pin.

The wires for the switch control unit; the center terminal will make contact to one of the two outside(red or green on the remote) terminals through the switch remote control, to test the solenoid jump either outside pin to the center and one of the two will through the switch.

Also make sure you have the insulated pins in their proper place or the switch will act crazy.

If  memory serves track power is supplied thru the flat buss  you re soldered. If you follow the buss back it has a short vertical stud on the other end.  This makes contact with one of brass contacts on the stationary half of the switch.  Confirm a good connection of the stud and  contact  when switch is reassembled.  Usually one can gently raise the contact up a bit to insure good contact.  The contact used depends upon which way the switch motor is oriented to the switch.

If the light is on, track power is getting to the switch motor section.  By far the most common issue with these is the sliding contacts.  I use a contact forming tool to adjust the contact tension on the sliding contacts, and you should also clean the contacts for best results.

Thanks for the help but I think I have done all of that, but still missing something. I will try improving the contacts on the sliding part, that must be it.   Already spent way too much time on one lousy switch!  

I know the feeling, for a $20 switch, sometimes it's best to cut your losses and retreat.
