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.
Using a PH0 / Phillips #0 driver, remove the 3 screws shown in red.
Peel away as little of the pads as possible, in order to preserve the adhesive on their undersides.
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.

The switch's brand is Omron. Part number: D2FC-F-7N. Components have 3 pins leaded type (two utilized)
I experienced one switch working intermittently. In such case, I recommend replacing both L & R switches.
