    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?

    don't know squat about the KD push buttons but sounds like you have dust or dirt in them .

    I'm not familiar with the Kadee pushbuttons, but if they are like any other, once they go bad, it's best to just throw them away. Using them on a CD unit shouldn't screw them up thought.

    'm using some old pushbuttons on a temporary panel I built to test my new tracks, but I eventually will go with the three-position, spring-loaded miniture toggles. I get them at Circuit Specialists. I bought a lot of switches from them when we had our electronic manufacturing business and you can deal with them on the net or by phone. I paid a little over a dollar each for them. Another source is Demar Electronics that adveertise in MR mag. Prices there are a bit higher. I can't vouch for them since I've never bought there, but they advertise all the time.

    I have a couple of Kadee pushbuttons left, but they're out of use. Kadee stopped making them a while ago, I'm told. Never found anything else that size.
    Are these the ones with the big metal clip that goes around the barrel? I had problems with that when I tried to solder to it.
    Not sure about replacements. Radio Shack buttons seem to expire quickly; I think there are identical looking ones that are sturdier.
