Or just think about the last ten years of war news coverage and build a simple pressure plate like what is commonly found along the scenic roadways of the middle east. Two metal plates with an insulated spring separating them.

Those are designed for one-time use, though....

Last year for my group senior design project (child hand eye coordination game) we created switches from DDR dance pad foam and Pure Copper Polyester Taffeta Fabric. The switches were responsive and we never had issues with a stuck switch. The video below shows the switches in action.

It's super easy... take a thin metal plate.... cut some squares of 1/8th inch thick strip insulation (the stick on stuff you use for filling door frames and what not) and place them in a few locations on the plate, preferably the corners and one in the middle. Now put another thin metal plate on top. You are done....
Your weight will compress the insulation so that the plates touch.... attach your switch wires to each plate. If you pull apart those cheap ddr matts, they all work on this principle. (Although they usually use pieces of foil or something flexible.)
ChadTower:
For a home made pad, though, you probably want something that will last longer than some foam. Those pads become unreliable before long. Some short metal springs from the hardware store will probably do the job.

Some good ideas here, I'll try them and see how they work out.
