Akai GX-F90 Button Repair

**UPDATE 6/2024**
5mm cross snap dome works better than the ButtonWorx (Snap domes)
The original button center post is designed to touch the board at all times and the outer ring touches when pressed. ButtonWorx™ pads will be touched all the time. The only reason they work at all for this is because the buttons are horizontal instead of vertical so gravity doesn't press down at all. The snap dome button will never activate on it's own and provides good snap back button return.

The left pad shows the orientation of the snap dome so that the legs cannot touch the center pad trace.
The right shows the 5mm cross shape dome installed. 

Received and installed yesterday.
Great product, works great.
Thanks a lot

Using ButtonWorx™ Universal buttons FOUND HERE 

ButtonWorx™ membrane keypads stick to the circuit board, not to the rubber keypad. Nothing sticks to rubber which is why 100% of repair attempts to "fix" rubber keypads fail. Instead, ButtonWorx™ membranes are a NEW thin keypad you insert between the old buttons and the circuit board. This turns your old rubber keypad switch into a rubber "key cap" that presses down on the new ButtonWorx™ membrane switch. 

ButtonWorx™ material does not wear out, cannot fall off and will never peel flake or chip. Shelf life is far longer than 20 years (that's how long I've been using this material)  and I have tested these in a machine that pressed the button 3 times per second for over 1 million button presses with no degradation in conductivity or operation. The machine broke twice in testing, the buttons did not!
