FIELD: locks.
SUBSTANCE: present invention relates to locks installed in the entrance doors of hotel rooms, designed to turn off electrical consumers when leaving the room. The lock contains a body with a guide for the key, an electrical contact installed in the door jamb that interacts with a bolt placed in the guide groove and having a bolt plate equipped with a comb and a locking post, a means for locking the bolt, including a set of spring-loaded levers with code protrusions formed by notches for interaction with the locking post, a second bolt placed in its guide groove and a double-bit key. Additional guides are installed on the inside of the housing, coaxial with the guide grooves. On the lower plane of the upper crossbar and on the upper plane of the lower crossbar there are teeth that interact with the gear mounted on the axis. The code protrusions in the grooves of the levers, located closer to the crossbar, correspond to the secrets on the bits of the key inserted from the corridor when it is turned completely. The code protrusions in the grooves of the levers, located further from the bolt, correspond to the secrets on the bits of the key, inserted from the number when it is turned completely. The guide for the key is equidistant from the extreme notches of the levers.
EFFECT: it is possible to operate the control mechanism of the second bolt from the corridor in order to open the lock.
