ABSTRACT:
An elastomeric rocker switch assembly (10) which is particularly suitable for hand held industrial controllers includes an elastomeric switch pad (11) having one or more rocker switch blocks (13) suspended within a sheet (12) by a thin, flexible and resilient web (14). A base plate (25) is provided to support the sheet (12) and to provide a rocker fulcrum point (27) for each rocker switch. An electrical switch supporting member, here printed circuit board (29), is positioned in spaced relationship to the underside of base plate (25), the circuit board having one or more pairs of momentary push button switches (30) thereon, one pair per rocker switch. Switches (30) are positioned to interfere with the underside of the rocker switch when the switch is pivoted about its fulcrum point.
