Inertial array switch using ball bearing, manufacturing method of the same, car airbag sensor and projectile fuze power supply switch using the same

摘要

The present invention relates to an inertia switch. More specifically, the present invention relates to inertia switches using the ball bearing. According to the invention, formed from an electrically disconnected state with one pair of electrodes facing each other, the substrate surface; The binding on the substrate, the partition channel formed along one long direction, and in the passage in a second store which is located on the first storage section and the electrode pairs, and smaller than the first storage unit and the storage unit and the second flow path width flexible doors with Euro width (flexible door), having a body portion; And comprising a ball bearing that behavior along the guide groove, the more the value when the inertia force is applied the ball bearing ball bearing fixed to the door by passing the flexible storage and moved to the other characterized in that for changing the capacitance between the electrode pairs The inertia switch is provided with a ball bearing. Since inertia switch with a ball according to the present invention uses a ball-bearing fracture phenomenon does not occur it is possible to correct operation.
