Some of these gurus are admittedly respected veterans of companies such
as Tektronix, with whom mere mortals are loath to argue. All I can say
is, those switches must not have been of the greatest quality in the
first place, or the gurus wouldn't have to spend so much of their time
on Usenet warning people against hosing them down with WD-40.

LOL. Well, some switches on oscilloscopes are very fragile with many,
many contacts, and rather low contact pressure. Sometimes hermetically
sealed too, so you can even use a spray can of Spam or shaving foam and
it won't hurt a bit
