INTRODUCTION
There are 3 methods to repair a faulty left, right or document flip button in this device.
1) Its likely only one buttons has stopped working, so you can desolder another of the button
switches 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 tactile switch having only 2 pins instead of the more common 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 Panasonic part used in the mouse is a 0.74N part. Larger forces
create a bigger clunk!


Study how the antenna wire in front
of the mouse wheel and the mouse
wheel assembly are located into the
PCB. You'll need to know this when
you perform the re-assembly. Also
note which side the power switch is
set to.

Remove the mouse wheel from the
assembly, then remove the PCB.

The tactile switches for the left, right
or page down buttons are tall black
and square devices. One can be
seen next to the wire in the picture.

Step 4

The new EVQ P0E07K can be seen in the image.

Using your soldering Iron, de-solder the old switch by placing tweezers under the switch for
leverage whilst heating the pins.

You may find it easier to wriggle the switch out one pin at a time, rather than heating both pins at
once.

De-solder the holes with the solder pump or wick.

Insert the new buttons and solder, ensuring they are flush with the PCB.

Re-assemble the mouse carefully ensuring the power switch, lens, antenna and mouse wheel are
in the correct locations.

Test the switch works acceptably before screwing the unit back together.
To reassemble your device, follow these instructions in reverse order.
