- contact cleaner on phone pad
- Posted by johngood_____ on September 11th, 2007
One particular number on my phone dial pad requires more and more pressure
for it to connect. The phones about three years old.
Its now so difficult to use, only those with the strongest fingers can press
hard enough. Would a contact cleaner be worth using? Or a waste of time
since some kind of coating might be wearing off, since I think that usually
the number pads are basically rubber with some kind of coating on the
contacts.

I asume that a 'broad band' of coating must have failed, otherwise I
fail to see why you posted to THIS newsgroup...! Or it is an IP phone...

I can tell you most catagorically that IPA or other contact cleaner will
DESTROY the thin carbon coat on silicone pads!
Initially it sometimes appears to help, but in a very short time the
problem gets worse until the darn key won't work at all.
The only repair that MAY work - but isn't guaranteed - is to use a keypad
contact repair 'paint' This stuff is very expensive - several pounds for a
tiny vial, and has a very short shelf life once opened.
The only truly reliable fix is a new keypad membrane.
