Trouble With Real Trax Switch

If you move the switch-block (the module with the red/grn rotating lamp) to the other side of the switch does it still chatter?

What happens if you swap switch-block between switches?

If you rotate the lamp to manually force switch positions is the "feel" of the action the same for both switches?

Sounds like a crossed wire / short somewhere. Check for wires/rail touching where it should not.

Isolate potential problems, seperate the switches from the track and each other and see if they operate well free standing.

By and large these switches are well done pieces IMO.

mine did this, seems I put the mechanism on the other side, no problem.

Check the embedded magnet on the side that chatters. If it come part way out, it does not let the motor return to where it should and trip the microswitch inside the unit.

Moving from one side that does not works to the other side and then the second side works, is a good indicator that the throw is not happening all the way.

If the magnet is not pushed in all the way in the switch body, push it back. If it is loose and still wants to come out, glue it.

That is the easiest solution if the magnet on one side is the problem. If it is not, look for one of the inner rails to be grounded to the adjoining track. Most would advise tape or grinding a little off of the offending rail making contact.

Hope this helps. Greg
