Abstract (en)
[origin: US4459441A] Multiple limit switch comprising telescope plungers (16), each of which has a U-shaped anti-rotation element (62) engaging over the inner end of the plunger, this anti-rotation element comprising a hole (68) for the inner portion (44) of the plunger to pass through and forming an abutment for the plunger return spring (70). The outer portion (40) of the plunger has a collar (56; 56'), behind which projections (64) of the anti-rotation element (62) engage, this outer portion (40) having lateral flattened portions (58; 58') to secure the outer portion (40) of the plunger against relative rotation. The flattened portions abut against slide guide surfaces (60) of the anti-rotation element (62) or edges (64') of the latter. The anti-rotation element (62) is non-rotatably held in an inner groove (30) of the limit switch housing (10).
