Logitech Mouse G302 Disassembly

Flip the mouse over to gain access to the bottom.

Using a scalpel, pick, or similar tool, peel away the slide pads on the bottom of the mouse in order to expose the three screws.

Peel away as little of the pads as possible, in order to preserve the adhesive on their undersides.

Using a PH0 / Phillips #0 driver, remove the 3 screws shown in red.

Gently separate the two halves of the case. Light prying may be required.

For PCB removal : remove 3 PH0 screws from PCB surface. The whole PCB can be taken out for inspection and repair after the screws are removed.

I experienced one switch working intermittently. In such case, I recommend replacing both L & R switches.

This is helpful for finding the correct replacement or compatible replacement e.g. vendors from online store AliExpress.

I used this as a successful replacement: RS Components Stock No. 682-1519 microswitch. Manufacturer is Omron, manufacturer part number is D2F-F.
