Abstract: 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.
