Therefore, the rotation lever 8 is pushed by the force of the magnetic force line of the electromagnet applied from the outside when the power is turned off, and rotated to one side by the hinge point of the fixed shaft (2), and to recover that the power is cut off By applying an artificial force to the recovery handle (3), the rotary lever (8) rotated to one side to the original function to switch the power supply so that power can be applied.

A first stator magnet 4 is inserted into an upper position of the pivot lever 8, and an end of the first stator magnet 4 becomes an electromagnet according to application of power, and the first stator magnet 4 is provided. The solenoid (9) having a polarity and the opposite polarity of is mounted. In addition, the second stator magnet 17 having a polarity opposite to the first stator magnet 4 is mounted at a position spaced apart from the first stator magnet 4 by a predetermined distance.

In addition, a contact piece 5 for applying power is fitted in the lower position of the pivot lever 8. One side of the contact piece 5 is connected to an external main message, that is, (+) power input terminal 13 to which (+) power of the vehicle battery is input, and the other side of the contact piece 5 has a wire ( 6) is connected to the power output terminal (7) for outputting a positive power.

Here, the solenoid 9 is connected to the (-) power supply terminal 14 for supplying (-) power from an external battery, and the (+) power is connected to the (+) power input terminal 13. It operates by receiving power. At this time, the (+) power input terminal 13 also receives (+) power from the battery.

The (-) power supply terminal 14 is connected by a shock sensor for contacting by a predetermined magnitude of impact due to a collision of the vehicle to conduct (-) power of the battery.

The shock sensor is installed in a horizontal state of the vehicle traveling direction, as shown in Figure 2, a predetermined space is formed inside the sealed case so that dust or impurities do not enter, and the sensor case Cylindrical contact ring 22 upright from the bottom surface within the (19), the impact detection spring 24 is installed upright in the inner center of the contact ring 22, and one side is connected to the contact ring 22 In addition, an external (-) power input terminal (23) branched from a (-) wire drawn out from an external battery by the other side, a sensor output power terminal (21) connected to the shock detection spring (24), and the shock detection spring It is mounted on the upper end of the (24) and the impact is applied to the contact ring 22 by the bending force of the impact detection spring 24 as the impact is applied a predetermined speed or more from the outside, the sensor output from the external (-) power input terminal 23 Internal contact point 20 for conducting to the power supply terminal 21 side It is configured.
