New ALPS Switch? ALPS Grey Linear

[rzwv]

It is the switch attached to the STOP key of NEC PC-9801-98-S02.
The color of the lower cabinet is different and it has become light black.
The special feature was linear and bottomed out at 130g.

The point of contact is not being fixed by a baked rivet.

hasu has one. I have listed it here:

I have actuation force at 120 g; hasu wrote:

With my coin stack measure,
yellow needs 60g to actuate while grey needs around 120g. Popular green Alps goes with 50g and Cherry red with 40g for comparison.

I found very very heavy Alps on PC-8801 keyboard before, IIRC it required around 230g :o But it's being lost on messy desktop now :)

You have bottoming out force at 130 g. That seems wrong.

It is interesting that the lower shell is grey. Normally it is the upper shell that is grey, with a black lower shell:

I don't know whether this is an "official" Alps switch, or whether it was a custom product made only for NEC.

Also, there is no Alps logo on the bottom!

Although he thought that Deskthority wiki was checked, it was the axis already written.
I made you trouble.

Your measurements are different from hasu's. I wonder whether he measured "actuation" as bottoming out force by mistake.

You also have a lot more pictures and information that I have not seen before, especially the missing Alps logo.

I've discussed this with hasu. By my calculations, we have, assuming an arbitrary 30 g preload:

rzwv: 130 g to bottom out implies 80 g actuation. The Alps 1994 catalogue lists SKCLAQ, grey, 0.882N, which fits perfectly. This is also around the same weight as amber Alps ("NYC taxi yellow").

hasu:[/i] 120 g to actuate (suggesting 180 g to bottom out) would be a very different switch. One thing to note: rzwv's has a logo and a short white switchplate.

SPARC suggests, for the Futaba switch PC-8801 Mk II, that the STOP key switch is 250 g, compared to 60 g with the exterior spring removed. 250 g is heavy regardless of whether it is bottoming out force or actuation force.
