Alps SKCL Yellow, or yellow Alps, is a linear switch in the "complicated" Alps SKCL/SKCM series.
Yellow Alps have an LED recess; the LED occupies the position where the tactile or click leaf should go. Typically this recess is left empty. It appears that switches ordered without an LED pre-fitted lacked the LED holes in the lower shell.
Yellow Alps appears to be the longest-running product in the SKCL/SKCM series. It appears to have been introduced around 1988, with approximately two years' overlap with Alps SKCL Green; the latter appears to be slightly lower in force. The earliest yellow Alps switches had long slits and no Alps logo, but by 1990 or so the mould had been replaced with one with the Alps logo and short slits. The SKCLAR/SKCMCQ data sheet along with MouseFan's data suggests that the slits were never removed.

Colour comparison with Alps SKCM Amber (right)
Yellow vs green
The following used switches originated in a Zenith ZKB-2 AT keyboard. They are assumed to be SKCLAR as they match the 1994 Alps catalogue specification. Being shipped without LEDs fitted, the base does not accept LEDs without suitable holes being drilled into it.
The following switches are NOS surplus from China. They are assumed to be SKCLFQ (per the 1994 Alps catalogue) based on their characteristics.
