I found the post here to link over there. to Classic Toy TrainsJohn, The 1122 & the 022 switches should be reconditioned for best reliability. I did a number of 1122 switches and posted a procedure on this forum for fixing them. The plastic they are made from will cold flow, and this caused the crimped connections inside the switch to become loose.
You know I did a long post on the CTT forum about restoring 022 switches. Use Google to search for it: 022/711 switch operating pblms
After 50+ years, both types of switches can use some reconditioning.
What is the procedure for removing the plunger? I'm interested in knowing if it can be removed without also removing the frame and coil assembly.One other thing: if the normal reconditioning procedure doesn't give you the snappy performance you want, consider pulling the plunger for a buff and hone.
