For some reason, several of my devices are starting to have this same issue.

The little lighted push buttons are starting to 'stick'. They seem to electrically 'work' (ie. enabling/disabling when pressed), but the light stays lit unless I 'twiddle' it.

There's no obvious cause (liquids, etc.) It just seems to be time that has caused it.

I've tried 'exercising' them repeatedly to no avail.

And BTW, it's not just one vendor... I'm having this with gear from several makers so either they all use exactly the same switch -or- it's just something that 'happens' with this sort of switch.

So... how does one 'unstick' these things? Surely there is a 'procedure', right? Right? Very Happy

Dis-assemble and clean.

Or shoot with contact cleaner, what is easier.

By 'contact cleaner', you mine like Deoxit?

Sorry for being so thick. These things don't disassemble so easy.

In that instance, without dis-assembly, I'd more likely use like an all-in-one, or both the De-Oxit cleaner followed by the luber (red than blue, or just the gold, if I recall ...)

Now, if they see it, I expect some more expert dudes might object to my advise, so YMMV.

Hi,

Since it is happening to more than one device... there might be something in the air. Too much humidity? Cigarette smoke? Mary Jane smoke? Skanky funk from musicians (LOL)?

There are different methods to clean switches and pots. All depend on the TYPE of material to be cleaned.

Yes, the CAIG products can handle most situations, BUT, some CAIG products can cause problems.

Which devices are having issues? Do you have a service manual for them? Many service manuals can be found online for free or cheap.

Try to open the simplest one, and then use a magnifying loupe and strong light to see up close and try to find what gunk might be present. Report back here afterwards, maybe with pictures.

Skanky Funk may be my new band name ...

Often that sort of thing is gunk around the actual button where it goes through the panel. Much easier to clean if you can take it apart. Contact/switch cleaner generally not very effective on that sort of problem.

contact cleaner can potentially make more gunk by attracting dust and debris as it dries and mixes together

I've seen some rubbery material buttons turn to actual liquid after 20-30 years - like melt onto your fingers as black tar

I'd recommend taking em out and cleaning with 99% alcohol if they're not rubber and lightly test on plastic parts first for any adverse reaction - use a foam swab not a q-tip
