Abstract
Position switch whose box houses a switch assembly that can be manoeuvred by an activation head using a push button. The head 20 is inserted in a recess on one surface of the box 10 so that it can be angularly adjusted at regular intervals, and towards the box, has a tubular bearing surface 25 in which the plunger slides. The bearing surface 25 is equipped with notches C1 at regular intervals and the recess 14 of the box has corresponding notches C2 around its outside. A fork 15 that can be locked by a lock 33 blocks the head in its assembly position.

Switch, more specifically a position switch, comprising a box, containing a device (13) movable along a travel axis (X1) and an electric switch assembly (12), activated by this device, while a manoeuvre head (20) is mounted so that it is removable and angularly variable in a recess (14) of the box, opening onto a mounting surface (10c) of the box. The head has a tubular bearing surface (25) housing a push button (23;50) activated directly or indirectly by an object, and able to slide along the translation axis to operate with the movable device,
- characterised by the fact that:
- the tubular bearing surface (25) of the manoeuvre head (20) is equipped with external notches (C1) spaced at regular intervals,
- the recess (14) of the box has internal notches (C2) around its outside operating with the notches (C1) of the head and of the same interval as these notches or at multiple intervals,
- external notches (C1) and internal notches (C2) fit together along the translation axis of the movable device.
Position switch comprising a box (10) containing a device (13) that moves along a translation axis (X1), an electric switch assembly (12) activated by this device, an L-shaped manoeuvre head (20) with two branches (20X1,20X2) assembled so that it can be removed from the box. The head has a push button (23) activated by an object via a pivoting lever (30) able to rotate around a pivoting axis (X2) perpendicular to the translation axis (X1) and operating with the movable device, characterised by
- the first means of angular adjustment of the head (20) in relation to the box (10), and the second means of angular adjustment of the pivoting lever (30) in relation to the head (20),
- the first means of adjustment include the first external notches (C1) of the head (20) provided at regular intervals on the first branch (20X1) and the second means of adjustment include the second notches (C3) provided at regular intervals on the second branch (20X2) and the first and second notches engaging respectively with the operating notches (C2,C4) along the translation axis (X1) and the pivoting axis (X2).
