    摘要： An end switch for use with a shaft and a drive which drives the shaft through a relatively large number of 360.degree. angular rotations associated with an end position wherein the end switch is provided with a switching member and with a spindle drive means responsive to the drive for causing an end face of the switching member to be brought into engagement with a contact of a stationary switch at the end of the rotation of the shaft. In accordance with the invention, the spindle drive means moves the switching member axially thereto during a first portion of the shaft rotation and tangentially thereto during the remaining portion of the shaft rotation, the former portion being larger than the latter portion.

    摘要： A rotatable cam limit switch with a switch operating cam mounted directly on a continuously rotating drive shaft and axially shiftable relative to the shaft. The drive shaft is also provided with a "fast thread" for adjustable axial positioning of a timing element in slidable engagement with the cam. Manual axially adjustable yoke elements respectively engage the cam and timing element for establishing preselected switch dwell time and phase relationship between said switch and said shaft.
