'''LK Optic''' (Chinese: '''LK光轴''') is an infrared optical switch from [[Bloody]]. The design is based on [[Kaihua PG1511 series]], with the [[metal contact]]s replaced with an infrared emitter and detector. The slider includes a shutter that blocks the light reaching the detector until the key is pressed. "LK Optic" is also used to refer to the more complex [[Bloody LK Optic 2]] switch.

"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.

The OEM is not known. Bloody's diagrams depict the shell as looking like a PG1511 series switch, and such a switch is used in a comparison photo, but no evidence appears to exist to tie the two companies together.

It is likely that the switches accept [[Cherry MX mount]] keycaps, but this is not confirmed.
