Replacement Button Board for G304 G305

This replacement button board is designed specifically for Logitech G304 and G305 gaming mice. It restores function to worn or damaged left and right mouse buttons. The part suits repair technicians and owners comfortable with soldering and disassembly.

Thermals Noise and Power Draw

As a passive mechanical component, the board generates no heat and produces no audible noise during operation. It draws no electrical power of its own, relying entirely on the mouse circuitry. Normal use adds no thermal load to the device.

Switch Rating Determines Compatibility

The board is offered with Kailh 8.0, HUANO, TTC 80M, 50M or Red Dot micro switches rated for 50 or 80 million clicks. Selecting the wrong switch rating or height will prevent proper installation and function. Verify the exact variant against the product image before ordering.

Questions about this item

How do I install the YINGHUA button board in my G304 or G305 mouse, and what step do people often get wrong?

The board replaces the original micro-switch PCB for the left and right buttons. Special skill and techniques are required; verify your exact model and compare the product picture before soldering.

What maintenance or replacement will this button board need later?

The Kailh, Huano, or TTC micro switches are rated for 50 million or 80 million clicks. When the switches eventually wear out, the board itself can be re-soldered with new switches of the same footprint.

What limit shows up first under sustained use of the YINGHUA button board?

The micro-switch click rating is the first limit — 50 million clicks for standard switches or 80 million for the 80M variants — after which button actuation becomes unreliable.
