<p>1,044,136. Mechanical switches. SWFSPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU. G.m.b.H. Jan. 26, 1965 [Feb. 22, 1964], No. 3328/65. Heading H2B. A steering column electric switch mechanism for automotive vehicles adapted to be arranged below the boss of the steering wheel and having an operating lever 7 displaceable parallel to the steering wheel plane and extending towards the steering wheel circumference has an additional actuating member for closing the contacts of an additional switch actuable independently of the steering column switch. The additional actuating member 11 is a rod the length of the operating lever 7 and guided therein. It is operated at one end by a button 12 having moulded to it stop springs 13 engaging behind a bead 15 of a gripping sleeve 14, with a retractive spring 16. The other end of rod 11 forms one contact (connection to the rod being via lever 7) which when depressed touches a contact plate 19 (Fig. 3, not shown) self-retained by a projection 20 (Fig. 3) in an insulating housing 8 which also houses the contacts 24 (Fig. 4, not shown) of the steering column switch, which has a ball-and-catch latching mechanism 4, 5 (Fig. 1, not shown) and spring return cams 9 and detent 10. Socket 18 allows the axial position of lever 7 to be adjusted to allow for wear of contact 11. Alternatively the end of rod 11 may bear on a separate contact spring to contact plate 19.</p> |
