The Durock Ice King is a fully transparent linear mechanical keyboard switch. Top housing, bottom housing and stem are all clear, so RGB from the PCB passes straight through and lights the keycap evenly instead of leaking out of the sides. If you have a board with per-key lighting and want it to actually show, this is the sort of switch to put in it.
Underneath the looks it is a medium-weight linear: 52 g to actuate and 62 g at the bottom, with a 20 mm progressive spring that starts light and firms up as you press. The switches come factory lubed and ready to install, sold here in packs of 10.
