In Fig. 5, when the movable stop pin 9 springs up against the spring force of the spring member 10 from the groove 6 of the inner cylinder member by the insertion of the magnet key 7, as shown in FIG. The magnetic sensitive switch which detects it and is in the closed state is formed in the inside.

Examples of the magnetic sensitive switch 11 include the switch member 11A using the fixed contact piece 11a as the fixed contactor and the movable contact piece 11b as the movable contactor in FIG. 7 or the magnetic sensitive type shown in FIG. The lead switch 11B is used.

Thus, in the present embodiment, the switch member 11 using the magnetic sensitive switch is appropriately assembled in the various outer holes 3 of the outer cylinder member 2 as shown in FIGS. 3 to 6, respectively. The switch member 11 is connected in series and protected by the cover body which is not shown in figure.

Next, reference numerals 12 shown in FIGS. 1 and 2 denote door switches that turn on when the door of the vehicle is opened, and a load 13 which is an electric appliance is connected to the door switch 12.

14 is an alarm, such as a rich person connected between the switch member 11 of the key cylinder lock 1, and the said door switch 12, This alarm 14 is a switch member 11 in this embodiment. ) And the door switch 12 are turned "on" to energize the battery 15 of the car to power an alarm.

Further, reference numeral 16 denotes a room lamp connected via the door switch 12 and the room lamp switch 17.

In the above configuration, before the magnet key 7 is inserted into the key hole 8 of the key cylinder lock 1 as shown in Figs. 3 and 4, several magnetic pin tumblers 9a at the stop pins are provided. And 9b are pressed by the spring member 10, are located in the groove 6 of the inner cylinder member, and the several magnetic sensitive switches 11 as the switch members are in an open state.

Thus, as shown in FIGS. 5 and 6, first, when the magnet key 7 is inserted into the key hole 8 of the key cylinder lock 1, the magnets embedded in the magnet key 7 ( g1) and g2 act on the magnetic pin tumblers 9a and 9b of the same poles corresponding to each other, and the magnetic pin tumblers 9a and 9b are grooves of the inner cylinder member 5, respectively. From 6, it springs up against the spring force of the spring member 10, and approaches each magnetic sensitive switch 11. As shown in FIG.

Then, each magnetic sensitive switch 11 detects it and is in the closed state, respectively.

By the way, when forgetting to remove the magnet key from the key cylinder lock 1 and opening the door, the door switch 12 is turned "on", and the current from the battery 15 of the car is changed to several switch members 11, ( 11, the alarm 14, the door switch 12, and the electric load 13 are energized, respectively, so that the alarm 14 is turned on as long as both switches 11 and 12 are in the " on " state. Sound the alarm.

Next, another Example of this invention is described.

In addition, the same parts as those of the embodiment of the present invention are denoted by the same reference numerals, and redundant descriptions are omitted.

In the first embodiment shown in Figs. 9 to 14, the key cylinder lock 1A is mainly different from the embodiment of the present invention.

That is, the key cylinder lock 1A is formed in the outer cylinder member 2a, the inner cylinder member 5a formed so as to be rotatable in the outer cylinder member 2a, and the outer cylinder member 2a. And the movable pin 25 formed in the inner cylinder member 5a by the spring member 10a as a driver pin 26 for pressing in the radial direction of the key hole 8a for the improved magnet key 7A. In the appropriate place of the thin thickness part of the said outer cylinder member 2a, the several through-hole 27 which can form several magnetic sensitive switches 11C as a switch member is formed.

Thus, also in the above configuration, when the magnetic key 7A is inserted into the key hole 8a of the key cylinder lock 1A, the respective magnetic sensitive switches 11C and 11C are in the "on" state. .

Therefore, when the door is opened, the door switch is turned "on", and it is possible to prevent the alarm from ringing and forgetting to remove the key as in the above embodiment.

In the embodiment shown in Figs. 13 and 14, the main difference from the embodiment of the present invention is that the timer TM is formed.

That is, the controller 30 having a timer TM for operating the alarm for a predetermined time between the switch cylinders 11 and 11 of the king cylinder lock 1 and 1A and the alarm 14 is provided. Forming.

In the above configuration, the switches of the switch members 11, 11 and the door switch 12 are turned "on" so that the current from the battery 15 of the car is alarm 14 and the door switch 12. ), The alarm 14 may be energized for the output time of the timer TM, or an alarm may be generated without energizing, respectively.

In the present invention, the key cylinder locks (1) and (1A) have been described that the key of the key switch for the ignition switch is the cylinder lock, but the key cylinder lock is a lock formed in the lock or the trunk of the door of the vehicle. It may be.

The number of the switch members 11 formed in the key cylinder locks 1 and 1A may be singular.
