Electrical switch especially for an automotive vehicle

The switch has four electrical conductor paths supported by a support (200). A contact part (100) has main tabs (130, 140) supported permanently against the support to modify connection state of the paths (202, 204) when the part is stressed in a plane parallel to the support. The part has secondary tabs (160) supported at contact of the other two paths when the part is stressed in a plane perpendicular to the support.
