I'm sure this has been covered before.
I have 3 of the modern O22 switches ( made in china #6-14062 - Left Hand ) I bought these switches new in 2009 so they have been on my layout for 5 years. I finally got around to adding wood ties and ballast to my tubular track the past month. One of these switches started to fail after gluing down the ballast. Pulling up tubular track after it is in place is a pain, but I pulled out 2 of the switches. The electrical contacts under the switch rails are worn out. The moving contacts have eroded the metal foil, so the elec. contact is lost. I also have 2 switches that I bought back in the 1980s ( #5132 ) and 2 old PW O22 switches that I bought used a few years ago. these switches show no problems. Boy - I wish I had not bought these poorly made switches and had gotten used PW O22 switches.
I bought a 1/4 wide 12 inch long brass strip from a hobby shop. I'm going to try to replace the worn out foil with the brass and see what that does. Next week is the Rocky Mountain Train Show in Denver and I plan to go, so I am going to be on the look out for 3 PW O22 switches.
So my question is repair or replace ?
