Omron switches, D2FC-F-7N (60M). I purchased many for repairing my mouse (MX Master 2S / MX Master 3), but I have some left over, so I'm selling them. These have a durability of over 60 million cycles. Please refer to the manufacturer's datasheet for details. This is a set of 2. Shipping will be via Yu-Packet Post Mini. Thank you.
