Back in 2020 or so, TTC made slider-over-membrane key 'switches' which weren't really switches, just discrete slider units with a spring-loaded push pin that stabbed at a membrane. These were used by a few keyboards such as the Xiaomi Yuemi MK03C mechanical-feel keyboard:

Then they vanished without trace.

I would actually like some of the switch units for another project, to mount over an existing membrane, but I can't find these things for love nor money. Does anyone know what happened to them? Are they, or something similar, still available under a different name?

I saw an Alibaba listing for them.

4000 MOQ, anyone up for a group buy?

Thanks, I think... I was planning on trying to 3D print a mount to let me retrofit those onto my ZX81, but that's enough for 100! They'll do samples, but only up to 10, and it would cost ~$1 for the switch things and $75 for shipping. I'll have to find a reseller.

Another absurd project these might work for is to find an extremely broken model M chassis and membrane and 'repair' it...

Maybe grab some low-profile normal switches and handwire them?
