Key Takeaways:

• Alps SKCL/SKCM switches are a cherished collection among mechanical keyboard enthusiasts.
• They feature a unique switchplate design and tee mount pins.
• These switches have a rich history dating back to at least 1980.
• Disassembling and understanding the variants of the switches require careful attention.
• Various keyboard models have featured Alps SKCL/SKCM switches over the years.

Nomenclature and Description of Alps SKCL/SKCM Switches

When it comes to the Alps SKCL/SKCM series switches, the nomenclature can be a bit confusing. While they are commonly referred to as “SKCC” switches based on keyboard codes, consistent naming by Alps Electric remains unclear. Interestingly, the Apple III service manual lists them as “KCC”. Regardless, these switches are an integral part of the iconic Alps SKCL/SKCM series, known for their exceptional quality and unique features.

One distinguishing characteristic of these switches is their switchplate design. They feature tee mount pins and cruciform slot keycaps, which contribute to their remarkable tactile feel and smooth keystrokes. While the majority of switches in this series have side-mounted pins, certain keyboards incorporate switches that are rotated by 90° for specific layout requirements. There is even one keyboard that utilizes mixed orientations of these switches.

It’s important to note that the Alps SKCL/SKCM switches are not rotationally symmetrical. They have small nubs on the sliders which need to align with indentations in the keycap mount for proper operation. Additionally, the plate mounting holes for these switches measure 14 mm square.

The Alps SKCL/SKCM series switches date back to at least 1979 and have been found in various keyboard models over the years. Their durable construction and exceptional performance have made them a favorite among mechanical keyboard enthusiasts and collectors alike.

Evolution of the Alps SKCL/SKCM Series

The design of the Alps SKCL/SKCM series switches has undergone several evolutions, resulting in different variations and features. These switches were produced alongside the SKCC series, and both series were found with switchplates in black, grey, tall white, and short white.

Throughout their production, the Alps SKCL/SKCM series switches underwent various design changes. One notable change was the addition of chamfers to the bottom of the switches, which helped improve the overall design and functionality. Additionally, alterations were made to the shape of the exterior recess in the base, further enhancing the switch’s durability and performance.

In some batches, terminal sealant was used, providing additional protection and stability to the switches. Furthermore, a ridge was introduced in the base to securely hold the switchplate in place, preventing any unwanted movements or misalignments.

The production of the Alps SKCL/SKCM series switches continued until at least 1989. However, the exact timeline of these design changes and the full extent of their variations are not currently clear. Further exploration and research are needed to uncover more comprehensive information about the evolution of these switches.

Key Design Features of the Alps SKCL/SKCM Series:

• Chamfers added to the bottom of the switches
• Changes in the shape of the exterior recess in the base
• Use of terminal sealant in some batches
• Introduction of a ridge in the base to hold the switchplate

Disassembly and Variants of the Alps SKCL/SKCM Series

Disassembling the Alps SKCL/SKCM series switches requires some caution, as the side tabs are thinner and more fragile than those of the SKCL/SKCM series. To prevent damage to the switches, proper techniques and additional tools may be necessary.

The variants of the Alps SKCL/SKCM series include different part numbers and specifications. These switches are known for their tall momentary switches, believed to be part of the subseries “A,” and the standard height momentary switches, regarded as part of the subseries “B.” However, more data is needed to confirm this theory. The switch variants also differ in color, weight, slider height, and keystem height.

• Switch disassembly requires caution due to thinner and fragile side tabs
