120piece set of switch sound dampeners for mechanical keyboards. Thin 0.5 mm PORON pads designed to sit between the switch plate and PCB to reduce cavity noise, damp vibrations, and improve switch feel without affecting the circuit board. Key benefits Effective noise reduction for a quieter typing and gaming experience. Thin 0.5 mm PORON material preserves switch travel and actuation while damping hollow cavity sound. Designed to attach to the side of the plate near the PCB to absorb vibrations transmitted through the switch housing. Improves insertion and alignment of switch stems during assembly. Pack of 120 pieces covers multiple switches for fullboard or partial installs. Features Material: PORON foam Thickness: approximately 0.5 mm Quantity: 120 pieces per pack Placement: filler between positioning plate and PCB, attached to plate side near PCB Function: reduces vibration and cavity resonance from switch actuation, facilitates stem insertion How it works These silencers act as a thin cushion between the plate and PCB, absorbing energy transmitted through the switch housing when keys are pressed. By reducing vibration and partially filling the cavity, they lower hollow or pinging noises common in mechanical keyboards while maintaining switch performance. Use scenarios Mechanical keyboard builds: Install during assembly to reduce cavity resonance and create a more muted sound profile. Gaming setups: Quiet down rapid key presses for less distracting sound during long sessions. Office or shared workspaces: Minimize keyboard noise to maintain a quieter environment without altering switch feel. Package contents and notes Includes 120 switch silencer pads. Thickness is approximately 0.5 mm. Please allow 12 cm measurement variation due to manual measurement. Actual color or appearance may vary slightly from images due to monitor differences.
