Patent ID: 7987688

Claim:
A turning knob with a lock for an electrical circuit, comprising: a body; a stator housed in said body and defining a plurality of openings, said stator having a plurality of positioning members; a barrel defining an opening for a key and configured to turn inside said stator, the barrel including locking tabs configured to be received in said openings in said stator, said barrel including at one of its ends a shank actuatable by rotation of the key, wherein the body includes an internal cylindrical sleeve, the stator being positioned on said internal cylindrical sleeve, wherein the internal cylindrical sleeve includes a plurality of identical positioning members, each positioning member of the internal cylindrical sleeve being complementary to and collaborating with a corresponding positioning member of the stator so as to establish multiple positions of the stator with respect to the body, wherein each stator position, when held in engagement with the internal cylindrical sleeve, corresponds to a different rotational orientation of the openings in said stator with respect to the body, wherein the different rotational orientations of the openings in the stator, in cooperation with a rotational limit of the barrel within the stator, provide a variable number of key withdrawal positions.
