Contract for Stewart Smally? You could try etching a pattern and soldering on little bits of spring steel with a slight "S" bend like: _,- then lay a mat of rubber over it to make a low duty cycle bouncy keyboard at about any size. I did that once and it worked ok.... for a while....

Hi, all; I'm looking for some really small switches for a tiny keyboard. Want to find some that're under 4mm square or so. SMD would be great, for this. 2mm would be unbelievably great Something like "tactile switches", as they're called. I'm starting to think I'll be doing carbon conductive switches for this thing... I figure a nice SMD PIC on there would do for a keyboard monitor, if I can find the switches. Otherwise I'll have to make some cobbled together nightmare with stacked layers of switches and push-rods, ACK! I'm thinking of a way to use those 3mmx6xx rectangular switches with pushrods if I have to, but other options would be far better. Mark -- I re-ship for small US & overseas businesses, world-wide.
