“LK Optic 2” refers to a clicky switch from Bloody. In English, Bloody still call it “LK Optic” (and refer to Light Strike Technology, of which “LK” is an abbreviation, instead of Light Strike 2 Technology) while in Chinese it is referred to as “LK二代光轴” (LK II optical switch), “LK2光轴” (LK2 optical switch), “LK光轴” (LK optical switch) or simply “光轴” (optical switch).
The switch is unusual in having a design that is totally new, resembling no other known switch. The internal mechanism is of a curious and unclear design, and one that is described as clicky and offering a “machine gun” sound.
“Key response” is given as 0.2 ms, citing an 18–30 ms “delay” due to contact bounce in metal contact switches. Contact bounce is typically given by manufacturers as 5 ms maximum, and it is not clear where the 18–30 ms comes from.
It is likely that the switches accept Cherry MX mount keycaps, but this is not confirmed.
