Abstract: A switching device, capable of being applied to the steering column of an autovehicle is described. The device comprises a sleeve which is provided with a front seat for housing one of the releasing pawls. The releasing pawl is capable of engaging with a shaped sector formed in an annular body operable by means of a radial lever connected to the steering wheel. The shaped sector presents a substantially concave central portion delimitated by two tooth raised portions and two nearly flat side portions. The annular body supports a resiliently biased contact plate and is provided with a cylindrical seat in which is housed a resilient pin. Near the annular body is located a disc structure on which are arranged three fixed contacts having suitably sized contacting surfaces. The fixed contacts are connected to the contact plate by slightly rotating the annular body. The device permits to avoid a double operation for each signalling maneuver.

Abstract: A junction box for a motor vehicle electrical system for coupling electrical conductors extending from the rear of a vehicle with conductors extending to the front of a vehicle, comprising an integrally moulded body having removable end, top and bottom walls and an intermediate plate which can be slidably engaged in guides in the side walls of the body. The removable end and bottom walls are provided with connector units for connecting electrical conductors of the external circuit to the junction box. These connector units are interconnected internally by flexible printed circuit connectors which also make contact with actuating elements, such as relays, and with printed circuit fuses mounted in sheets on pivoted support plates by means of which fuse changing is facilitated.

Abstract: A light-transmission device includes an elongated cylindrical member bounding an internal passage and having an open end and an opposite end which defines a first socket, and a light source received in the internal passage and which extends from the open end towards the opposite end of the elongated cylindrical member. The device further includes a cable terminal which tightly surrounds a plurality of light-conductive cables. The ends of the cables are trimmed and maintained in a plane at a light-impinging end of the terminal. The cable terminal and the elongated cylindrical member are connected together by a connecting member which has an end defining a second socket which receives the light-impinging end of the cable terminal and an opposite end having a plurality of engaging portions which extend into and engage the first socket.
