Cherry mx clear mechanical switches
The Cherry MX Clear switch is a medium stiff, tactile, non-clicky mechanical keyboard switch in the Cherry MX family.

The slider is not actually clear but colourless (in effect, translucent white). The word Clear is Cherry's own designation to distinguish it from the older Cherry MX White which is a clicky switch. Older types of the "white" also have translucent white sliders and are therefore visually indistinguishable from clears.

The Cherry MX Tactile Grey switch is used for space bars in keyboards with Cherry MX Clear switches. It has a similarly-shaped stem but a stiffer spring.

MX Clear is reported to have first appeared in 1989; however, it was included in a March 1988 numbering system datasheet for MX switches so it is assumed to have been in production in 1988 or earlier.
