Abstract
Abstract The ''''push or pull'''' of a segmented shaft means which carries a cam means for actuating switches responsive to cams, actuates an actuator means which in turn actuates a contact blade to open and close electrical contacts. The shaft segments are coupled together through spring washer means. One segment carries the cam means, while the other segment axially moves to actuate the actuator means.
