摘要

SWITCH OPERATING TIMING MECHANISM COMPRISING AXIALLY DISPLACEABLE SHAFT A first shaft of two concentric rotatable shafts is axially displaceable with respect to the other. Switch opening and closing means is responsive to the axial displacement of the first shaft, the axial displacement being responsive to the rotational output of the second shaft. A cam means is carried by the second shaft.
