This is sold in 1 set (2 pieces). The plates have been tested with some Cherry MX, Gateron and Kailh switches. The switches can be snapped nicely because carbon fiber sheets with 1.5mm thickness are used.
Thickness: 1.5mm (approximately)
Switch holes: 14.0mm × 14.0mm (approximately)
M2 screw holes: Ø2.4mm (approximately)
Important note: There might be minor scratches and uneven surfaces/edges. For Kailh and Kailh low profile choc PG1350 switches, you’ll need to use a larger force to insert the switches. Cherry MX and Gateron switches are generally easier to be inserted. Optionally, you can sand the edges.
