The lock has a mobile button (4) in a casing (3) with an eccentric command rod (7) for a lock bolt (9) which is closed by a spring (10). The button has an axial bore in which is mounted a rotating cylinder (12) activated by a key which allows the button to be locked and unlocked. There is a sensor (40) which detects the key in the rotor which is mounted in the button. When there is no key the sensor penetrates the rotor, when the key is inserted the sensor fits in the housing (44) of the lock so that the button is locked.
