The present invention concerns a control device for electronic apparatus of the electronic stem type, adapted to be shifted between a plurality of axial positions. According to one preferred embodiment, the stem (1), with axis X, has four different axial positions. Two contact clips (21, 22, 60, 61) mutually offset in the direction of the axis X are provided to make contact with two respective power supply terminals (19, 20, 75, 76) of a source of electrical power supply. The stem comprises a plurality of cylindrical portions (36, 38, 50, 51, 52) which cooperate with deformable extensions (27, 28, 64, 65) of the contact clips to deform them in a direction substantially perpendicular to the axis X. Thus, in accordance with the axial position of the stem (1), the contact clips (21, 22, 60, 61) can be in different electrical states, i.e. isolated or connected to the source of power supply, independently of one another. As a result the assembly formed by the two contact clips can exhibit four different states, each being representative of a given axial position of the stem.
A control device for electronic apparatus, comprising a stem with an axis X, said stem being shiftable along said axis between at least four different axial positions, wherein said device comprises two contact clips, each comprising a movable contact element adapted to be displaced between at least two positions and to make electrical contact with an electrical power supply terminal in at least one of said positions, the two contact clips forming an assembly adapted to provide four different electrical states representative of respective said axial positions of the stem, said power supply terminals being connected to a same electrical conductor having, at least in the region of connection of said power supply terminals, the shape of a plane substantially parallel to said axis X,
