ABSTRACT:
To be used in operating one or more end switches, one or more cams are mounted on a switchbar, with each cam having two parts with angularly related surfaces that move towards and away from each other by means of a head screw so as to clamp against two correspondingly angled parts of the switchbar, to draw the cam transversely against the side of the switchbar. The switchbar is provided with a V-shaped groove, so as to provide two angled surface portions for respectively engaging two cams mounted respectively on opposite sides of the switchbar, so that the same may be moved past each other in the direction of elongation of the switchbar without interfering with each other.
