What customers say
Customers highly praise the Gateron Lunar Probe Linear Switches for their exceptional out of box smoothness, often comparing favorably to custom lubed alternatives. The deep, satisfying thock sound profile significantly enhances the typing experience. Reviewers appreciate the premium feel and unique aesthetic design.

Know before you buy
The double-stage spring provides a more consistent and snappy return speed. Because it is longer than a traditional spring, it creates a slightly more uniform resistance throughout the entire keypress, which helps prevent the feeling of 'mushiness' often found in linear switches.
Yes, these are 5-pin switches, but they are fully compatible with 3-pin hotswap boards. You can simply clip off the two extra plastic guide pins on the bottom of the switch using a pair of flush cutters to make them fit.
POM is a self-lubricating plastic known for its low coefficient of friction. Using it for the stem ensures that the switch remains smooth over time and reduces the scratchiness often felt during the initial break-in period.
Hand-lubrication is recommended if you want a deeper sound profile and a smoother feel right out of the box without doing the work yourself. The filmed option is best if you are sensitive to housing wobble and want to ensure the tightest possible fit for a more refined acoustic signature.
A 50g actuation force is considered a medium-light weight. It is light enough to prevent finger fatigue during long gaming sessions or extended typing, but provides enough resistance to avoid accidental key presses.
