Kailh introduced their newest lineup of mechanical keyboard switches at Computex 2018 in the form of the Sun switch. The aim of this lineup was to retain the Cherry MX keycap compatibility with the same stem design, but allow for centralized lighting akin to what Omron did with their light pillars in the Logitech Romer-G and Creative PRES switches. This meant designing new molds for the various switch parts, and also finding a wider spring that together all still work into providing a tactile and clicky switch with a 1.8 mm actuation depth, total travel distance of 3.5 mm, an actuation force of 50 gf and tactile force of 60 gf.

It found little interest, however, with only Hexgears choosing to adopt it to date in their GK760 keyboard. In a move to drum up more business, Kailh have already updated the Sun switch to allow for a clear stem with walls surrounding the stem to help add some dust and spill resistance, with the clear housing now allowing more light to pass through. The rest of the switch is identical, as seen below in samples we received recently (old switch at the left/top of the new switch), although now there is little scope left for a more diffused backlighting experience. Time will tell how the changes work out, and yours truly would have rather seen the older design in use.More pictures follow.
