I have bought several used 022 switches in the past month. Most were in pretty good shape, but a little slow. I followed the board advice on Services 022 switches, and now they work really well, except of one annoying thing.
None of these switches came with a constant voltage plug. No problem, I bought a half dozen new ones.
Yet, for about half of my switches, when I connect the constant voltage wire to the plug, and put the plug in, making sure that it is going over the interior pin and not on its side, the connection is terrible. It is spotty. I have to jiggle, bend, play with, etc. the plug, until suddenly the switch light comes on, and then back away and pray it stays that way. Some do for a good while, but then the vibration of trains passes over causes whatever connection there is to jiggle loose or shift, and then I have lost the connection again.
On some of these connections, I have to push the plug in all of the way, and then very very gently back the plug out a hair of an inch, to get the light to come on.
Has anybody had these problems? Is there any cure? Or, did I just get a bad run of the replacement plugs?
