Abstract

Rotary-controlled multipole electric switch fitted with a handle (4) and a housing (1) in which a cam device transforms the rotation of the handle into a translational movement of contact bridges (21). In order to ensure coordination between a cylindrical control core (13) and a slider 16 bearing contact bridges, the cam device is fitted with at least two notches (19, 20) offset around the axis of rotation X of the knob (4c), and with a control projection (14) applied respectively to the bottom of one notch in the OFF position and to the bottom of the other notch in the ON position by the force supplied by springs (24) acting on the slider and contact pressure springs (22).
