The motor vehicle switchgear includes a single set of conductive tracks on a flexible support, simplifying the structure. The steering column switch comprises a support box (1) mounted on a tube fitting around the steering column. The box includes switches for lighting (2) and for screen wipers (3). The mobile contacts (54,66,67,70,82) of the switches are mounted on the rear surface (9) of the box. The fixed conductive tracks are formed on a flexible circuit on the rear surface (9). This flexible circuit is connected to an electronic circuit mounted in a seating (24) formed in the top surface (4) of the box (1). The flexible circuit may be reinforced to provide extra rigidity in the region of the switch tracks. The flexible circuit also includes an extended portion connected to an anti-theft switch module, and may include connectors for linking to other supplementary functions of the device. The box (1) is closed on the rear surface by a further cover.
