Abstract
A position switch whose box houses a switch assembly that can be maneuvered by an activation head holding a push button and located in a recess on one surface of the box so that it can be angularly adjusted at regular intervals. The head has a tubular bearing surface facing the box and in which a plunger slides for actuating the switch assembly. The bearing surface has notches at regular intervals for alignment with corresponding notches in the box recess. A lockable fork retains the head in position.

A limit switch, comprising a box, containing a device movable along a translation axis and an electric switch assembly, activated by the movable device, a maneuver head removably mounted for angularly variable movement in a recess of the box, said recess opening onto a mounting surface of the box, the head having a tubular bearing surface that houses a push button for activation by an object, and able to slide along the translation axis to operate with the movable device, wherein:
- the tubular bearing surface of the maneuver head has external notches spaced at regular intervals,
- the recess of the box has a periphery and internal notches located on said periphery and cooperating with the external notches of the head and located at an interval identical to the interval of the head notches, and
- the external notches and the internal notches fit together along the translation axis of the movable device.
A limit switch, comprising a box containing a device movable along a translation axis, an electric switch assembly activated by the device, an L-shaped maneuver head comprising two branches removably attached to the box, head having a push button activated by an object via a pivoting lever for rotation around a pivoting axis perpendicular to the translation axis and operating with the movable device,
- first means for angular adjustment of the head relative to the box, and second means for angular adjustment of the pivoting lever relative to to the head,
- the first means for angular adjustment further comprising external notches of the head located at regular intervals on the first branch and internal notches located in the box, the external notches of the head and the internal notches of the box cooperating along the translation axis, and
- the second means for angular adjustment further comprising first indexing notches located at regular intervals on the second branch and second indexing notches located on the pivoting lever, the first indexing notches of the second branch and the second indexing notches of the pivoting lever cooperating along the pivoting axis.
