Product details

OwLab London Fog Linear Switches (10 Pack)

Smooth, consistent, long-pole

The OwLab London Fog is a linear mechanical keyboard switch designed by OwLab and manufactured by BSUN. It pairs a long-pole UPE stem with polycarbonate housings and a 20 mm spring, and comes lubricated from the factory for a smooth, consistent keypress from the first press.

At 55 g to actuate and 60 g at the bottom it sits in the medium band: light enough for long typing sessions, with enough return to keep fast typing clean. Sold in packs of 10.

What to expect

Feel

A clean linear press with no bump or click over 3.6 mm of travel. The long-pole stem meets the bottom housing a little earlier and more firmly than a standard stem, so the bottom-out feels crisp and defined.

Sound

Long-pole stems and polycarbonate housings tend to give a brighter, more clacky bottom-out. Expect a clear, poppy sound rather than a muted thock.

Materials

UPE is a very slippery plastic, so the stem glides in the housing with very little friction. With the factory lube on top, there is nothing to do before you install them.

Q&A & Specifications

Questions & Answers

Will these fit my keyboard?

The London Fog is an MX-style switch. It fits hot-swap boards with MX sockets and can be soldered to a standard MX-compatible PCB.

What does long-pole mean?

The stem's central pole is slightly longer than usual, so it hits the bottom housing before the stem's legs do. That shortens the travel a touch and gives a firmer, sharper bottom-out.

Are they lubed?

Yes, they come factory lubed and are ready to install as they arrive.

How many do I need?

Count the keys on your board. A 60% needs around 61, a 65% around 67, a 75% around 82 and a TKL 87. Each pack holds 10, so round up and keep the spares.
