INERTIAL SWITCH USING A BALL BEARING, MANUFACTURING METHOD THEREOF, AIRBAG SENSOR USING THE SAME, AND FUSE OF A SHELL

摘要

PURPOSE: An inertial switch using a ball bearing, a manufacturing method thereof, an airbag sensor using the same, and a fuse of a shell are provided to prevent malfunction by preventing the breakdown of a droplet.;CONSTITUTION: A body unit(5) includes a flow path(51) and a flexible door(55). The flow path is combined with the upper side of a substrate(1). The flexible door divides the flow path into a first storage unit(52) and a second storage unit(53). A ball bearing(7) moves along the flow path. The ball bearing with inertial force above a preset value changes electrostatic capacity between electrode pairs by moving to another storage unit.;COPYRIGHT KIPO 2012
