Know before you buy
This 0.5mm foam layer sits between your PCB and plate to dampen high-frequency vibrations. It creates a deeper, more 'poppy' sound profile and provides a slightly softer bottom-out feel while typing.
No, this specific foam is precision-cut for the Keychron Q1 ANSI knob version. It is not compatible with ISO layouts or non-knob models.
The foam is engineered to complement the acoustic properties of the 'flexy' case and plate foam set. Using it with the 'firm' version may result in an inconsistent typing feel or unwanted interference with the keyboard's internal mounting structure.
Not at all. The foam is designed to accommodate standard Cherry MX style switch housings, ensuring they seat properly into the PCB without obstruction.
No adhesive is needed. The foam is held in place by the pressure of the switches being installed through the plate and into the PCB, making it a non-permanent modification.
