[more] [/more] Hm, I've been very wrong about things all day....or usually. But I think that's what they called a buckling sleeve rubber dome.
Having a bad day, CPT?
Interesting. Took a better picture of the switch, hopefully it's clearer in this photo.MoreShow Image(http://i.imgur.com/Gu1VQHy.jpg)
That's why I want to see the underside of a keycap. I suspect it's a spring over membrane, but I can't say for sure without seeing the spring.Interesting. Took a better picture of the switch, hopefully it's clearer in this photo.MoreShow Image(http://i.imgur.com/Gu1VQHy.jpg)
Whoa, nice pic...
Yeah, def not a buckling sleeve. Looks to be some sort of spring-over-metal-contact type of thing... never seen it before.
I agree with the CPT... maybe someone else will know more about it.
you can see the membrane there. It could be buckling rubber sleeves, but I think it's a normal rubber dome sheet or a spring over membrane. Do you have a shot of the underside of a keycap?

I'm more interested in what it's from than the switch. What keyboard would have "Rotate Disc" on it?
Panasonic seemed to have some interesting keyboard, things having to do with MIDI, etc but I cannot track this one down.

THAT explains the SMK version of the Apple Keyboard II. I've never been able to figure out how it could have only one spring (the coil spring in the keycap).I think there are several other spring over membrane designs from other companies, no? This one doesnt look especially similar to the SMK one..?
The membranes are closed by the leaf spring under pressure from the helical spring. The SMK design has sliders and looks different, but SMK could potentially be the OEM.
Ahhhh!

Is this keyboard particularly interesting, or is it just pretty much worthless?
Ahhhh!In English it's usually spelled "Matsu****a". Dad used to work at their kenmore vacuum cleaner plant in Kentucky. Like Kenmore, Panasonic was a brand owned by the Matsu****a company. They have since changed their name to that brand though.

Ah, so it's not even a leaf spring, it's just bendy plastic Ouch.The Model M is also basically just bendy plastic, to be fair.

Edit: HaaTa's appears to be the same OEM, actually, as the differences between the two designs are marginal.

EH? I don't think any plastic piece on the model M bends in normal operation.

EH? I don't think any plastic piece on the model M bends in normal operation.I thought he was talking about the membrane sheet (which is the part that corresponds to a leaf spring in switches with leaf springs for the contact). Nevermind though.
