To install these switches, simply unscrew the two bottom screws, carefully open the back of the OP1, remove the main button switch cables, fold the shell to the left, and use a PH000 screwdriver to remove the switch PCB screws. Once you've added your preferred switch PCBs to the top shell, reverse the process. And if you're feeling adventurous, you can even use different switches for the left and right click.

To install the switches to the universal PCB, gently push them into the sockets, ensuring they align correctly and sit flush with the PCB. Remember, if the switches don't click after they're in the mouse, it's likely they're facing the wrong orientation.
