Title:
CYLINDER LOCK WITH SWITCH
Document Type and Number:
Japanese Patent JP3333985
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate a severe control about a mounting accuracy of a cylinder lock or a door lock and prevent definitely an operational failure that a locked and unlocked state detection switch detects and gives a warning before a rotary detection switch detects the turning of a cylinder lock.
SOLUTION: This cylinder lock is provided with a key lever 6 which is interlocked with a rotor 3 in the rotary direction and connected to a locking lever of a door lock device and a rotary detection switch 7 of the rotor 3 in this structure. In this case, a specified play angle in the unlocking direction is provided between the rotor 3 and the key lever 6 where the rotary detection switch 7 is arranged to detect the rotary motion in the unlocking direction of the rotor 3 in the range of the play angle so that the key lever 6 may be interlocked with the rotor 3 after that.
