Hello;

Anyone care to lend some advice on best practices when it comes to lubrication on the 027 Remote Control Switches?  This would be for either the older 1122 switch or the newer 5121/5122 switches.  On my layout I have converted all my switches to constant power as well as being modified for capacitor discharge.  I have even gone through the effort to install a master switch that turns on and off the constant power, thus putting them through less wear and tear.  My layout is now about 17 years old and as can be imagined does go through periods of non-use.  But lately it is active.

However a couple switches have become very sluggish to the point that while I can tell they electrically function, they no longer snap back and forth and need manual assistance.  Surprisingly, I cannot find any good threads where this is discussed on these switches.

Anyone have some advice?

They really shouldn't be lubricated except for maybe dry graphite or Neolube. Oils tend to attract  dust & dirt.

If you have the CD system wired correctly, there is no need to power down, there would be no additional wear associated with having constant voltage on w/o switch activation.

Cleaning the mechanisms would be the solution, unless somehow the solenoids have warped and the cores/slugs/armatures are binding.

Thanks Rob!

Any advice on how best to clean an 027 switch.

Do I need to remove the bottom plate to get at the linkage underneath?

Would you recommend to first try blowing them out good with air pressure from the top side and putting a little graphite from the top side?   That way I would not have to tear up a bunch of track to remove them.....

Thanks again.... Paul

Aerosol contact cleaner & compressed air. Hopefully, disassembly won't be needed, unless there is some kind of physical binding in the mechanisms. The O-27 switches shouldn't be screwed down or fastened on a layout, just floating between other track pieces so the bases don't get twisted or out of alignment... if they are screwed down, releasing the screw tensions may restore good operation.
