Electrical switches for mounting in control panels, especially for heating, ventilating and/or air conditioning systems for motor vehicles

An electrical switch for panel mounting, comprising:

• a set of electrically conductive contact strips comprising a plurality of primary contact strips and a secondary contact strip for power supply;
• a body carrying at least two conductive and electrically interconnected projecting elements, the projecting elements carrying at least three contact pads, the primary contact strips being substantially coplanar and the body being rotatable about an axis perpendicular to said plane;
• each of said projecting elements comprising a portion projecting radially from the body with respect to the axis;
• the set of contact strips defining, between two adjacent primary contact strips, a first tangential distance,
• each of said primary contact strips having a tangential dimension;
• wherein in certain predetermined rotational positions of the body, two of the three contact pads define an angular space between them and contact at least one of said primary contact strips, the angular space defining a second tangential distance greater than the first tangential distance and smaller than the tangential dimension of each of the primary contact strips, the other of said contact pads contacting the secondary contact strip.
