       027 - 1121 remote switches
       By: TrainmanMarty Date: May 5, 2020, 11:55 pm
       ---------------------------------------------------------
       I recently bought two 027 1121 remote switches. The RH switch
       seems to be always energized when track power is on.  The LH
       switch operates as expected.  It doesn't matter if the switch
       controller is hooked up or not. It sometimes goes off when the
       track is wiggled. If I can get it to de-energize, with the
       switch set to straight, when I run a train over it, the switch
       moves just enough to derail the loco coming from either the
       straight or curved track of the switch. It seems to move just
       when the loco crosses from the regualr track section to the
       switch.  I know that this switch is supposed to have a
       non-derail function, but I have not set that up as shown in the
       manual. I do have fiber pins in the rails as shown, but it makes
       no difference if I use fiber or steel pins.  Anybody have
       experience with this kind of problem ?  thanks

       Welcome to the forum!
       It sounds like the internal wiring may be shorting out, powering
       the switch with the locomotive weight on it, or by wiggling the
       switch as you say.
       Here is the wiring diagram of the 1121 switches:

       You may need to open up the switch to get at the wiring. That
       involves drilling out the eyelets, as shown here:

       Replacement eyelets, part #1550-8 are available here:

       Thanks for the info. However it doesn't appear to be a wiring
       problem in the switch. I bought another switch of a different
       model and swapped it out. The "new" switch does the same thing,
       it is always energized. The other 1122 is installed in the same
       track and operates normally.
       I moved the problem switch (LH) to another part of the layout
       and it does the same thing - always energized even without
       control wires attached.
       Could there be some sort of polarity problem with my power
       wiring ?  I tried reversing the variable power connections on
       the transformer with no change. Checked the wiring to the tracks
       and all are consistent (center vs outside rail soldered
       connections). Why would 2 switches always be energized and one
       work perfectly normally ?
       Since they are riveted together, I'd rather not have to break
       into them, especially if it is not an internal conection problem
       to begin with.
       Thanks,

       Since one switch works normally and two don't, the problem is
       definitely in the switches.
       Take the problem switches out of the layout and power them up
       with just 2 pieces of track connected to each leg of the switch
       and see if the problem still occurs. If it does, there is an
       internal problem in the switches.
       The 1121 switches do not have fiber pins in them, unless the
       switches are set up for automatic operation.
       There is no polarity in AC voltage, so the wiring to the track
       from the transformer is not an issue.
       Confirm that all switches operate properly outside the layout.
       What transformer are you using?
