    Q: how thick should a mechanical keyboards key switch layer be?

    A: 1.5 mm to 1.6 mm

    The standard thickness for a mechanical keyboard switch plate is 1.5 mm to 1.6 mm, which aligns with the official Cherry MX datasheet specification of 1.5 ± 0.1 mm.

    1.6 mm is the most common thickness for FR4/PCB plates and is widely accepted for 3D-printed plates to ensure rigidity. 1.2 mm is required specifically for Kailh Choc low-profile switches to allow their stabilizers to clip properly. Plates thicker than 1.6 mm (up to 3 mm for printed, or 4.5 mm for specialized designs) often require the switch notches to be carved or recessed, as standard clips may not engage correctly on thicker materials.
