Operating module for an anti-theft lock and associated anti-theft lock

A vehicle antitheft lock comprising:

• a stator;
• a rotor capable of being rotationally driven in the stator by a conforming key that includes an electronic identifier;
• and
• a control module comprising a support configured to be fitted on the stator and bearing an antenna connected to an identification unit able to:
• authenticate the electronic identifier of said key by exchanges of signals, and
• authorize starting of the vehicle when an authorized identifier is detected,
• wherein said support also bears at least one contactless switch able to change switching state when the rotor is rotationally moved,
• wherein the support comprises:
• a first part forming an antenna-holder implemented in the form of a cylindrical skirt covering the stator;
• and
• a second part bearing said at least one contactless switch and implemented in the form of a strip secured to the first part,
• wherein the strip bears at a free end an electrical connection plug, electrically connected on the one hand to the antenna and on the other hand to said at least one contactless switch, and
• wherein said plug is connected on the one hand to the antenna and on the other hand to said at least one contactless switch by stamped conducting tracks, the connecting ends of which in said plug form connection pins and the other ends of which form pads for contact with on the one hand the antenna and on the other hand the contactless switches.
