Toggle switch cleaning?


I have a preamp with a toggle switch for changing phase. Sometimes I lose the left channel on switching. Is this something that can be cleaned at home, simply and safely? Or can this be worn out?Thanks. Pete

From the front of the switch?
No, not from the front. Contact cleaner won't be effective unless it reaches the contacts.

Also, if the housing of the switch is completely sealed, with no slots or other small openings, spraying it from inside the preamp won't accomplish anything either. In that situation probably all you can do is to toggle the switch up and down many times, and see if that helps. If it doesn't, the switch would probably have to be replaced.

BTW, if and when you spray contact cleaner into whatever small openings may be present on the housing of the switch, there may be a temptation to look closely at what you are doing. Keep in mind that some of the spray will splash back from any surfaces it comes in contact with, and into your face and your eyes if they are too close. It may also emerge in a strong stream from any openings that may be present on the switch in addition to the one you are spraying into.

I suppose it would be reasonable to give that a try, Pete, assuming as I said that there is a way to get it inside the housing of the switch. I'm not completely certain, though, as Caig's D5 is more specifically intended to dissolve corrosion, while the G series is intended mainly as a contact enhancer/conditioner/protectant for contact surfaces that are already mostly corrosion-free.
