Abstract: A switch assembly comprises a housing, an actuating member mounted on the housing and a plurality of electrical switching members. The actuating member is able to translate frontward and backward and to pivot upward and downward, thus cooperating with the electrical switching members to control the roof displacements. The switch assembly further comprises two sliders solely able to translate along the longitudinal axis. The sliders are driven by the actuating member and are cooperating with the switching members in order to generate a switching function controlling the roof displacements. The switching function is derived from the positions of the switching members actuated by both sliders.
