Mouse Button PCB Board & Micro Switch Assembly for G304/G305

Bring your gaming mouse back to peak performance with this precision-engineered Left and Right Button Micro Switch PCB Board Assembly. Designed as a direct 1:1 replacement for the G304/G305 gaming mouse, this hot-swap ready kit comes with pre-soldered wires and a plug-and-play JST connector — no professional soldering skills required. Made in Mainland China.

Key Features

• Perfect Fit Compatibility: High-precision FR-4 glass fiber epoxy resin PCB manufactured using a 1:1 original size mold. Slots directly into the G304/G305 mouse shell without any extra modification, making the repair process straightforward.
• Stable Conductive Performance: Gold-plated copper connection pads deliver low contact resistance and excellent anti-oxidation properties, ensuring reliable current transmission and eliminating intermittent click failures during gaming or daily use.
• Durable Wire Construction: High-purity oxygen-free copper core wires wrapped in wear-resistant PVC insulation withstand repeated bending and friction, guarding against short circuits or wire breakage for a long service life.
• Tool-Free Installation: Pre-crimped standard JST connector at the end of the wire harness means you can complete the repair in minutes — no soldering iron or specialist tools needed.
• High Structural Toughness: A 1.6mm thickened rigid PCB substrate resists deformation and cracking under long-term repeated click pressure, maintaining consistent micro switch actuation feel for a stable gaming experience.
