Abstract

1403965 Gravity switches; inertia switches NISSAN MOTOR CO Ltd 12 Nov 1973 [14 Nov 1972] 52447/73 Heading H1N [Also in Division F1] An accident detecting switch for a vehicle comprises a conductive ball 30 which is normally held blocking aperture 20 by a magnet 32 but which on a predetermined deceleration bridges contacts 22, 26 and mercury normally in lower chamber 18 which, when the vehicle overturns, flows through aperture 20 to bridge contacts 26, 28.
