PROBLEM TO BE SOLVED: To provide a key switch device capable of selectively performing a turning-on or turning-off operation on a plurality of micro-switches by operations of inserting a key into a rotor of a cylinder lock and turning the key.SOLUTION: A key switch device 1 comprises: a cylinder lock 2; a support member 3 that is fixed in a rear part of the cylinder lock; and a plurality of switch box assemblies 4 which are coupled to a rear part of the support member while being laminated in a longitudinal direction. When a rotor 6 of the cylinder lock 2 is rotated by the key, the rotation is passed through a rotation drive member 9 and a rotation transfer member 21 and transferred to the rear-side rotation transfer member 21 successively. When the rotation transfer member 21 is rotated and a drive magnet 34 faces an operation magnet 33, the operation magnet 33 is moved to a pressing position and presses an actuator 19. By changing a holding position of the drive magnet 34 for each switch box assembly 4, the turning-on or turning-off operation is performed selectively on a plurality of micro-switches 18.SELECTED DRAWING: Figure 1 |
