ABSTRACT:
A switch apparatus (12) includes a substrate (20) of a resilient material having a first surface (40), with a channel (44 or 46) formed through the substrate to define a flex portion (48) of the substrate. At least part of the flex portion (48) of the substrate (20) is movable relative to the substrate between a first position and a second position. A layer of an elastic material (62) is disposed over at least a substantial portion of the first surface (40) of the substrate (20). The layer of elastic material urges the flex portion (48) to the first position of the flex portion. A switch element (53) is operatively associated with the flex portion (48) of the substrate (20) and has an electrical condition which varies as a function of the position of the flex portion.
