The topic is about switch contacts. Problem involving
switch contacts are different from problems inside a
potentiometer. Why? 1) Voltage and current levels are
radically different. 2) Switches (unlike potentiometers)
involve sharp continuity changes. Neither problem applies to
potentiometers. Clearing or greasing a potentiometer has
nothing to do with arcing, contact bouncing, and other power
switch problems. Please don't change the topic to something
completely irrelevant.

You said "grease on the switch contacts is NOT a good
thing" You posted inaccurately even after others posted
otherwise. That grease in sufficient quantity is a good thing
- in direct contradiction to what quietguy posted. Others
already noted that grease on switch contacts is a good thing.
Please just admit the mistake rather confusing the issue with
a potentiometer. Your reference to potentiometer only serves
to confuse people rather than admit to your mistake.

Bit of a rave on there w_tom - don't get your knickers in such a knot,
especially when you are wrong.

While you would be correct if one was specifying electrical contact
grease, the post I responded to simply stated grease - and to most
people that means ordinary grease like one uses to grease wheel bearings
etc etc. Not the sort of crap to put in a switch

So, before spouting off, next time Tom have a look at the post that is
being responded to before you start 'feeling' like posting silly stuff

Obviously you 'feel' a grungy contact is not good. It's
called being an old wife and promoting tales. It's dirty.
Therefore it must be bad.

As posted previously by others, that grease heavy on
contacts is there for good engineering reason. First learn
how contacts make and break electricity before just wildly
speculating. But to make it simpler to understand: remove
grease on those contacts to make switch fail fast.

Stop 'feeling' a conclusion. Stop using old wife
reasoning.
