摘要：This miniature normally open circuited acceleration switch has a hollowcylindrical casing closed at one end. Its other end is closed by a header having aninsulated axial lead wire extending inwardly of the casing, and an electrically conductivering secured peripherally to the casing. Inside the casing is an internally conical guidesleeve in which is a freely rollable massive ball. A lightweight cup-shaped piston in theguide sleeve carries a contact member spaced by an expanded coil spring from the leadwire. The ball impinges on the piston when a sufficient axially directed force ofacceleration is applied to the casing, even if a simultaneous laterally directed force ofacceleration is applied thereto. The piston moves axially against the spring bias such thatthe contact member contacts the lead wire to close the normally open circuited switch.
