Self setting and stabilized switch target

摘要

Apparatus includes a spindle having an outer surface configured with a surface finish that has openings/grooves, the outer surface also having an outer diameter; and also includes a switch target arrangement having a switch target in combination a target ring configured to be installed in the switch target so as to form the at least one switch target arrangement, and is also configured with an aperture having an inner diameter that is smaller than the outer diameter of the surface finish of the spindle, so that when the at least one switch target arrangement is installed over the spindle, interference causes at least a portion of the target ring to deflect into a groove/space of the surface finish of the spindle so as to energize the target ring to grip the surface finish of the spindle to secure the switch target when the spindle moves.

1. Apparatus comprising:
a housing having at least one switch sensor contained therein; a spindle having an outer surface configured with a surface finish that has alternating annular ridges and grooves/spaces formed along its longitudinal axis, the outer surface having an outer diameter; and at least one switch target arrangement comprised of:
a switch target, anda target ring configured or installed in the switch target to form the at least one switch target arrangement, and also configured with an aperture having an inner diameter that is smaller than the outer diameter of the outer surface of the spindle, the switch target with the target ring installed together over the spindle in an energized position, where an interference between the target ring and the spindle causes at least a portion of the target ring to deflect into at least one groove/space of the surface finish of the spindle and energize the target ring to grip the surface finish of the spindle to secure the at least one switch target arrangement to the spindle, the switch sensor configured to sense the switch target installed on the spindle in the energized position.
