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.
