INERTIA SWITCH Russian patent published in 2004 - IPC

FIELD: measurement of sustained accelerations in automatic systems of flight vehicles and safety systems of automobiles.

SUBSTANCE: in the inertia switch, having a body with a cover, inertia body and contacts, the body is filled with liquid, the inertia body is made in the form of a flat disk and is positioned in liquid in the body interior for plane-parallel motion between two plane walls, the value of motion is less than its diameter, but more than the clearance between the body wall and the flat disk in its initial position. The fixed contacts are installed in the body, and the movable ones are made of elastic material and positioned in circumference around the inertia body for engagement with it. In the initial position the flat disk is held by a magnetic system.

EFFECT: provided non-operation at high-frequency vibration-impact actions and provided measurement of accelerations under the action of vibration.
