The invention concerns a lock provided with a single switch to indicate the “open” or “closed” state of said lock, comprising an actuator (5, 6) acting on a kinematic chain (7) to produce the functions of the lock, a switch (19) adapted to indicate the states of the lock, a double-notched closure (2
The invention concerns a lock provided with a single switch to indicate the “open” or “closed” state of said lock, comprising an actuator (5, 6) acting on a kinematic chain (7) to produce the functions of the lock, a switch (19) adapted to indicate the states of the lock, a double-notched closure (2, 3) bolt (1), a pawl (9) including a pawl tooth (4) designed to be urged into engagement with the first (2) or second (3) notch for closing the bolt (1). The invention is characterized in that it comprises a mobile cam (12) for actuating the switch, said actuating cam (12) being mobile under the action of the bolt (1) and/or of the pawl (9) during the opening and/or closing phase of the lock.

1. A lock housed in a housing, the lock comprising: a single switch for indicating an “open” or a “closed” state of said lock;an actuator acting upon a kinematic chain so as to realize the functions of the lock;a bolt having a first closing notch and a second closing notch;a pawl comprising a pawl tooth designed to engage with the first or the second closing notch of the bolt; anda cam that is mobile in translation, wherein said cam is displaceable from an initial position corresponding to the lock being in the closed state, wherein the initial position of the cam comprises a position in which the cam buts against a recess of the housing, and wherein the closed state of the lock corresponds to the pawl tooth being in a butting arrangement with the second closing notch of the bolt during an opening phase and a closing phase of the lock,wherein the single switch is activated and deactivated under displacement of the cam, and wherein, during the opening and closing phases of the lock, at least one protuberance associated with both the bolt and the pawl engages with the cam to displace the cam, thereby activating or deactivating the single switch. 2. The lock as claimed in claim 1, wherein during the opening phase of the lock, the at least one protuberance of the pawl engages to displace the cam from the recess of the housing before the protuberance of the bolt engages with the cam, while during the closing phase of the lock, the at least one protuberance of the bolt engages to displace the cam before the at least one protuberance of the pawl. 3. The lock as claimed in claim 1, wherein the cam is accommodated in a recess of the housing of the lock. 4. The lock as claimed in claim 3, wherein the initial position of the cam is the position in which the cam butts against one end of the recess of the housing. 5. The lock as claimed in claim 3, wherein the cam contains a flexible tongue cooperating with a portion of the recess of the housing. 6. The lock as claimed in claim 4 wherein the cam contains a flexible tongue cooperating with a portion of the recess of the housing. 7. The lock as claimed in claim 1, wherein the cam is subjected to the action of a permanent force tending to return said cam into the initial position. 8. The lock as claimed in claim 7, wherein the initial position of the cam is the position in which the cam butts against one end of the recess of the housing. 9. The lock as claimed in claim 1, wherein the switch-actuating mobile cam is fixed to the pawl. 10. The lock as claimed in claim 9, characterized in that it comprises a fixed guide support capable of guiding the mobile cam. 11. The lock as claimed in claim 10, characterized in that the bolt comprises two protuberances designed to cooperate with the mobile cam. 12. The lock as claimed in claim 9, wherein the bolt comprises two protuberances designed to cooperate with the mobile cam. 13. The lock as claimed in claim 1, wherein the single switch comprises a plunger cooperating with a part of the surface of the cam for its activation/deactivation. 14. The lock as claimed in claim 1, wherein the switch consists of a Hall effect sensor and in that the cam comprises a multipolar magnet. 15. The lock as claimed in claim 1, wherein the actuator is an electric actuator. 16. The lock as claimed in claim 1, wherein the actuator is a mechanical actuator. 17. The lock as claimed in claim 1, wherein during the opening phase the pawl cooperates first with the cam, while during the closing phase the bolt cooperates first with the cam. 18. The lock as claimed in claim 1, wherein the switch-actuating mobile cam is fixed to the pawl. 19. The lock as claimed in claim 18, characterized in that it comprises a fixed guide support capable of guiding the mobile cam.
