Alps common mount low profile (or Alps octagonal for short) is a provisional name for a low-profile PCB mount switch from Alps.
Contents
Description
This switch uses the common Alps mount, unlike Alps SKFR/SKFS series which has a unique mount.[1] The slider design is similar to that of Alps SKCL/SKCM series, but reduced in front-to-back depth to fit inside the switch's small shell. The contact mechanism is very similar to that of Alps SKFL; the latter is cited as prior art in the patent.
Where SKFR/SKFS series has a black slider for linear and a colourless slider for tactile, the colours are reversed with common mount low profile: black for tactile as with SKCM series, and colourless for LED.
The only branding is a minute Alps logo in the centre of the base, visible only by desoldering the switch.[1]
The switch features an integrated jumper. The tactile version has a click leaf and likely arranges this in the same way as SKFR/SKFS.[2] The patent for the leaf (which curiously shows the base as rectangular instead of octagonal) describes the switch as "click-type", but a clicky version has yet to be encountered.
No keyboard has been found to date that offers a single letter of the switch series name. The only contender is SKFN, of which SKFNAA is the sole discovered model number. As these switches appear to be older than SKFR/SKFS, SKFN is plausible, but this theory remains wholly unconfirmed. As both linear and tactile versions exist, this is highly likely to be another back-to-back pair of series.
