TITLE CAM ACTUATED SWITCHING DEVICE ABSTRACT OF THE INVENTION A switching device comprising a spring pile- up assembly including a plurality of pairs of canti- levered stationary and movable contact springs secured between a pair of support members. A follower card is slidably mounted on the top portions of the support member allowing the follower to move in a plane 90 degrees to the contact springs. The tips of the movable contact springs protrude through openings in the follower card. A cam card including cam portions is slidably mounted to one of the support members perpendicular to the follower. As the cam card is moved the cams engage an edge of the follower causing it to be displaced in its plane of motion sufficiently to open a selected number of contact springs while allowing another selected number of contact springs to close.
