Kailh Box Red Pro 35g

My take on the Kailh Box Red Pro 35g: a featherlight, IP56 dustproof BOX linear with reduced stem wobble and a quick 1.8mm actuation, built for SMD-LED boards.

Frequently asked

How light is the Box Red Pro?

Very — 35g (±10gf) actuation makes it one of the lightest linears you can buy, ideal for fast actuation and minimal finger effort.

What's special about the BOX stem?

The boxed POM stem is dustproof and water-resistant (IP56) and reduces stem wobble noticeably compared to a standard cross stem.

Will it work with any LEDs?

Only SMD LEDs. The BOX stem housing isn't built for through-hole LEDs, so plan your board accordingly.
