How to use

Power off and disconnect the keyboard before attempting any repair.

Desolder the defective switch from the PCB or unclip it from the plate if the design allows hot-swapping. Install the replacement Kailh Box Brown switch into the plate, ensuring correct orientation of the pins, then solder or secure the switch in place. Refit the keycap and test the key for correct tactile response and electrical function before reassembling the case.

Usage recommendations

Use basic ESD precautions when handling switches and PCB components. If you are not experienced with soldering or keyboard disassembly, consider seeking professional repair assistance to avoid damage. Test each replaced switch before full reassembly to verify correct function and alignment.
