A device for controlling an electronic apparatus, comprising: a generally flat upper panel; a lower armature of a support with respect to which armature the upper panel can move in a generally vertically downward movement; a switch; and at least two arms for actuating the switch, each arm comprising a first end which bears on the upper panel, a second end which bears on the switch, and an intermediate portion which bears on the armature, in which the arms cooperate with the upper panel and the armature in order to keep the upper panel parallel to a horizontal plane during its vertical movement with respect to the armature.
