Low key count membrane keypads

Tact switches mounted on a pcb, some hole on the front plate, and a home made (or any other much fancy place) membrane to stick over the whole thing (front-plate). Neat enough, cheap enough, easy to repair/modify too.

Scary parallel processing - I've got a piece of scrap PCB at home with a tact switch covered with some clear silicone which is drying. I'm hoping the silicone will have not penetrated the switch but will provide a flexible enough seal over it.

Check out this keypad at Sparkfun. It is a silicon 2x2 with LED backlight. Kinda neat and you can build up other key matrixes using the parts. They also have 4x4, a 3 button gamepad like, and a 12 key membrane. The 4x4 can be cut in half to make 2 2x4 pads.
