Abstract
An electric commutator (20) with multiple switch ways comprising a horizontal upper panel (24) with an upper face (24s) that can be contacted by a pointing element, a supporting frame (22) and means (26) for locating the point of contact of the pointing element on the horizontal upper face (24s) of the upper panel (24) that comprise a plurality of electric switches (28) on the supporting frame (22) that are capable of being actuated selectively by the upper panel (24). The switches (28) are distributed on the supporting frame (22) so as to divide the horizontal upper face (24s) of the upper panel (24) into a plurality number of contact zones (44), the number of which contact zones (44) is greater than the number of switches (28).
