Inertia acceleration switch e.g for motor vehicle fuel feed pump

摘要

The switch (11) has a spherical object (18) and a holder (14) having an inclined surface along which the spherical object can roll, with a magnet element (20) for opening/closing a pair of contacts positioned above the holding element and acted on by the spherical object. The magnet element is held in an initial position via a permanent magnet (23), with spring blades (15,16) on opposite sides of the spherical object for clamping the ends of the magnet element at one end and cooperating with an electrode plate (17) at the other side.
