Keypads
 

Does anyone know of a way to restore function to over worked keypads?
This is one of those pads that have a thin plastic like membrane with a
very narrow gap between contacts. I am not sure what material they use
to seperate the contacts with, but half of the keys work and the others
feel like their almost flattened out inside. Any help would be greatly
appeciated! Thanks, Rob

they are carbon impregnated rubber buttons to make them
conductive.
mostly are dried, cracked and worped there by losing its
ability to conduct any more.
look for the applicable brush on product used for repairing heater
elements on automobile windows.






This one sounds different, more like the type used in many computer
keyboards where there's two sheets of thin plastic with traces printed
on them.
