I hope it is alright to post a question on this old thread. My question pertains to the  OMNI HAI 33A00-1 console.
 
Problem:
I am starting to have a problem with the "OFF" push button. A greater pressure, force, is required to make a contact completing its' function.
Has anyone ever cleaned a push button circuit contact button pad? My guess the circuit pad is dirty.
 
Thanks in advance.

Follow up:
 
I cleaned the printed circuit board switch circuit pads, and the rubber push button black conductive discs with isopropyl alcohol.
Keypad works like new.
