Alps SKCL Double Action is a double action switch in the first generation of the Alps SKCM/SKCL Series.
Characteristics
The switch follows the general characteristics of the SKCL family, consisting of an upper and lower housing, contact module, stem, and spring. However, there are many additional parts and changes. The housing is symmetrical, similar to SKCM Brown, the stem has a long pole and a recess for an actuator similar to the actuator in Alps SCK2), there is a second, brown switchplate with no actuator leaf (as the actuator is in the stem) and also a very stiff second spring in the base of the bottom housing to provide actuation feedback for the second stage. The tabs on the bottom housing are also not the full width of the switch, as in other switches in the series.
Additional Information
There is another version of this switch with an amber stem that appears to have been present in arcade machines3). Its part number, if any, is unknown.
