    摘要: An acceleration sensor comprising a cylinder of a conductive material, a magnetized inertial member mounted in the cylinder so as to be movable longitudinally of the cylinder, a conductive member mounted at least on an end surface of the inertial member that is on a side of one longitudinal end of the cylinder, a pair of electrodes disposed at this one longitudinal end of the cylinder, and an attracting member disposed on a supporting device near the other longitudinal end of the cylinder. When the conductive member of the inertial member comes into contact with the electrodes, these electrodes are caused to conduct via the conductive member. The attracting member is made of a magnetic material such that the attracting member and the inertial member are magnetically attracted toward each other. The magnetized inertial member comprises a core including a cylindrical permanent magnet, a hard plating layer formed on the curved surface of the core, and a conductive plating layer formed at an end surface of the core that is located on a side of the electrodes. Another magnetized inertial member comprises a cylindrical core including a permanent magnet, a synthetic resin layer enclosing the curved surface of the core, and a conductive plating layer formed on the end surface of the core that is located on the side of the electrodes.

    摘要: The acceleration sensor is formed of a cylinder; an inertial member slidably mounted in the cylinder so as to be movable in the longitudinal direction of the cylinder; a conductive member fixed at least on an end surface of the inertial member facing one longitudinal end of the cylinder; a pair of electrodes fixed relative to the cylinder at one longitudinal end of the cylinder and which, when the conductive member of the inertial member makes contact with the electrodes, are caused to conduct via the conductive member; and an attracting member fixed relative to the cylinder near the other longitudinal end of the cylinder, for magnetically attracting the inertial member. The electrodes are formed by a metal sheet whose basal ends are held by an electrode holding member and whose front ends are protruding in the travel area of the inertial member, and one of planes of the metal sheet is disposed so that it faces to the inertial member. In the acceleration sensor, the edge portions of the sheet metal forming the electrode are bent in the direction opposite to the inertial member.
