Try squirting WD40 right in the switch and work it several times.
This has restored a switch for me many times. In fact most times.
Cheap fix and nothing lost if it doesn't work.

Doug, an electrical contact cleaner would be my preference. The kerosene in WD40 can ruin plastic materials (insulation). It may hold up for a while but then it gets brittle.

OK here is the real deal. 9 years ago when we got our 3870 the shut down switch on the upper helm didn't work. I sprayed WD40 in the switch and it started working. 9 years later its still working.
That is real world and I have been doing this more than 10 years and can't recall a switch failing later because of that. And that includes some 110 volt switches.

But if you had done a little research before your post you would have found out you are wrong.
From the WD40 site.
WD-40 Multi-Use Product can be used on just about everything. It is safe for metal, rubber, wood and plastic.
And this.
While the ingredients in WD-40 are secret, we can tell you what WD-40 Multi-Use Product does NOT contain. WD-40 Multi-Use Product does not contain silicone, kerosene, water, wax, graphite, chlorofluorocarbons (CFCs), or any known cancer-causing agents.

While there is always something better, most do not have electrical contact cleaner aboard but many do have WD40.

There is more to using wd-40 than electrical cleaner.

It does displace water, good for guns, locks etc.

I used to use it as starter fluid. Don't know if that still holds true, because they have started using oil in starting fluid, many years now.

It's good for cleaning grease off your hands, stickers off cars and glass.

I used to spray it on rusted bolts.

Don't tell anyone but when i went camping with the Boy Scouts, and it was raining, i sent them out to look for wood and i started a few fires with it.

And yes i keep a can around, one in my truck for sure.

Give this a read:

Be good, be happy, for tomorrow is promised to no man !

It may not contain kerosene in the absolute sense but it definitely contains hydrocarbons and smells that way too.
I once ruined electrical stuff with WD-40 as it attacks the brown insulation (Pertinax) used quite often in older electrical gear (like switches). It swells the material which afterwards gets brittle. Just spraying it into something without knowing what's inside isn't what I would do any more after that experience.

Having used WD40 for this for so many years on more switches than I can remember without a problem, I have to ask.
Are you absolutely positive you would not have got the same results on anything you would have used on the one switch that you had problems with?
Remember WD40 says it will not damage a plastic. Think of their liability if it did.
