1. A pressure actuated switching apparatus which comprises: a) first and second conductive electrode layers, at least one of said first and second conductive electrode layers being movable in response to application of a mechanical force thereto from an open circuit first position to a second position wherein at least a portion of said first conductive electrode layer is in electrical contact with at least a portion of the second conductive electrode layer, each conductive electrode layer being electrically connected to a respective terminal of a power source for maintaining the first and second conductive electrode layers at different electrical potentials with respect to each other in at least the open circuit first position; and, b) a plurality of discrete, spaced apart dots positioned between said first and second conductive electrode layers, said dots being fabricated from an electrically insulative elastomeric polymer foam and resiliently biasing said first and second conductive electrode layers to the open circuit first position, wherein said dots possess a height of at least about 1/64 inch.
