Introduction
There are 3 methods to repair a faulty left, right or page down button in this device.
1) Its likely your left or right button stopped working, so you can de-solder the page down (rear-middle) switch and use it to replace the faulty button. Be careful they melt easily!
2) Buy a new Panasonic EVQ P0E07K tactile switch from a parts distributor. e.g. Digikey, Farnell, Mouser. This is a slightly unusual switch having only 2 pins instead of the more normal 4 pins. When purchasing, be aware that the P&P will often cost more than the switch. Try adding this to a larger purchase.
3) Use a longer switch but file it down to the correct height - height is critical! Be sure to get a switch with a low operating force. The fitted onePanasonic part used in the mouse is a 0.74N part. Larger forces create a bigger clunk!
