Alps SKCL Lock

|Product code||SKCLJC (grey)|
|Switch type||Alternate action|
|Sense method||Metal leaf|
|Switch mount||Plate mount|
Alps SKCL Lock is an alternate action switch in the Alps SKCL series. When the key is depressed, it locks into place and remains down there until pressed a second time. The switch has a normal switchplate, but the shell and slider are modified to accommodate the latching mechanism.
The front of the slider contains a recessed track, and the shell supports a follower arm that moves within this track. A loop within the track holds the slider down until the key is depressed a second time. The follower arm rotates about its lower end, which pivots within recessed area of the open-fronted upper shell; a bar runs across to keep the arm in place. The latching mechanism is partially visible when the keycap is removed, and the slider shape is a giveaway in itself.
All three variants of the switch are assumed to be the same specification. They nonetheless likely differ in model number.
|Brown||First generation; this appears to be the Gold Star Alps version made in Korea|
