Key Highlights

0.8 ms actuation – Infrared light-gate switching eliminates metal contact debounce latency.
100M cycle rating – No contact wear means the rating is the housing life, not the contact life.
Dust and spill immunity – Sealed light channel enables IP-rated board builds.
RGB light channels – Transparent top housings glow – ideal for RGB-forward aesthetics.
Esports positioning – The spec-sheet story competitive retail brands need.
