I have been having switch machine problems and traced the problem to non-functioning Kadee pushbuttons on my control panel. (If I go under my control panel & touch a wire to the PB case and the PB "stinger" the switches throw fine. Pushing the button with my finger however results in erratic or no action). - Has anyone else had this problem? - Is there a genetic flaw in Kadee PBs that I don't know about? - I use a capacitor discharge for switch machine power; Could this be relevant? - can the PBs be brought back to life? I was thinking of spraying them with WD40 or alchol, or something. (I find their tiny size aesthetically pleasing & would like to salvage them if I could). - Are there good, reliable alternative PBs on the market? - What about a spring loaded center-off toggle? Such a thing? Suppliers?
