1. Multiple contact mobile device comprising a stirrup (13) made of material which is a good conductor, rendered fast with the drive means of the device, a stirrup support (11) of insultating material, a spring (15) acting on the stirrup support (11), a row of rollers (5) rotatable about an axis (14), and springs (7) acting axially on the rollers (5), characterised in that at least one rocker arm (1) made of a highly conductive material is free to oscillate about an axis (3) made fast with the stirrup support (11) sliding on the stirrup (13) rendered fast with the drive means of the device, and in that the rocker arm (1) comprises at each end a pivot pin (4) called the roller pin, approximately parallel to the rocker arm pivot pin (3) and possibly free to be displaced with an angular movement in a plane perpendicular to the direction of displacement of the device, and carrying one or more rollers (5) pushed against the rocker arm (1) by one or more springs (7) acting axially, and in that at least one flexible conductor (18) is arranged between the stirrup (13) and the rocker arm (1). |
