Pro Light Green Switch
Kailh
The Kailh Pro Switch is part of the new series of Kailh switches. Different from regular switches, the Pro switch combines the best features of the Kailh Box switches and Kailh Speed switches to provide a cushioned stroke and a springy return. It features a faster and shorter activation period for a faster responsiveness than most mass-produced standard switches. That makes this switch an ideal and reliable option for gamers and typists.
