Up for buy it now are custom made AT&T Magnetic Separation Key Switch Testers.  I call them "tactile" and "clicky" versions. They originally had foam and foil pads below which dampens the plunger coming down on the PCB, but I've removed the foam/foil pad on one of these resulting in a "clicky" switch.  I would liken the difference in feel/sound between these two to the difference between an IBM Model M and an IBM Model F.  

Each lot is for ONE OF EACH KEYCHAIN SHOWN (one clicky and one tactile) with RANDOM KEYCAPS installed. The keycaps can be pretty tough to separate from the slider just due to the switch design, so I don't recommend trying to separate them if they seem stuck.
