A bare wire pressure plate can be constructed by simply removing the insulation from the wire used in the remainder of the circuit. Often the wire will be arranged in a pattern on two wooden boards, held apart at either end by soft spacers. This arrangement will be such that when pressure is applied an electrical connection will be made.

Another option that reduces the metal content still further is to use carbon rods. These are commonly available by breaking down some types of batteries. Again, they are often arranged on wooden boards in a manner that consistently makes a connection when pressure is applied. In this example a simple cross formation has been used.
