TP 560 - Sticking keys
Applicable to: World-Wide
Abstract :
2640 WITH STICKING KEYS.
When servicing a 2640 system replace the existing rubber sheet located beneath the keyboard, if it does not have rows of holes.
The following diagrams show an example of a sheet with no holes and a sheet with holes underneath it.

Sheet with holes
The part is referred to as a "KEYBOARD SHEET" FRU P/N46H4150 in the Mobile HMM volume 3 (MAY) 1996.
The holes stop the keys from sticking after being depressed by preventing a vacuum from forming between the bottom of the key and the rubber sheet.
