  • Switching apparatus employing conductor contracts on a movable elastomeric member
    Patent number: 4476357
    Abstract: An integral switch means on a printed circuit board is provided by a plurality of parallel conductor segments having insulating gaps which are aligned in a column transverse to the conductor tracks. Posts supported on the printed circuit board support and align a rigid support member for an elastomeric member having a plurality of conductor strips positioned to separately bridge the respective gaps of the connector segments on a printed circuit board when the elastomeric member is positioned against the printed circuit board. Spring biasing means extends between support posts and the rigid support member for normally urging the elastomeric member into the printed circuit board in position to close the switches. Actuator means is movably supported relative to the printed circuit board to cooperate with the support member to move the elastomeric member against the bias of the spring away from the printed circuit board.
