Alps SKCM Brown, or tactile Brown Alps, is a tactile switch in the complicated Alps SKCL/SKCM series.
Tactile Brown Alps is the original tactile switch in the SKCM series. Tactility was introduced by placing a second, modified switchplate actuator leaf onto a dummy block on the opposite side of the switch. This arrangement has been reported to have a superior feel to the later design.[Citation needed] Tactile Brown Alps has also been found with standard tactile leaves.[1]
The feel of tactile Brown Alps has been reported to be similar to the officially documented force curve of Alps SKCM Green switches, which have a tactile leaf of a shape quite close to that of tactile Brown Alps.[2] It is possible therefore that tactile Green is the successor to tactile Brown.
Linear Brown Alps switches also exist; these can be identified by an LED cutout in the upper shell.
