ABSTRACT:
A conical recess of an angle of 140.degree. to 170.degree. is provided at the lower surface of a separator member that is attached to the lower surface of a magnet maintaining a horizontal relation, and a steel ball is absorbed onto the center of the recess. The steel ball weight can sensitively and reliably respond to any low, middle and high frequency ranges, so that the weight falls overcoming the magnetic force to start the function. In addition to the foregoing, the retainer fitting of said magnet is supported by pairs of bearings each having a phase difference of 90.degree. so as to be oscillated in all directions, an oscillator plate is provided via a hanging member formed integrally with said magnet retainer fitting, a base of a receiving dish provided underneath the weight is so mounted as will be movable in the upper and lower directions, whereby said oscillator plate is oscillated freely when said base of the receiving dish is displaced upward, and said oscillator plate is fixed when the bed of said receiving dish is displaced downward, in order that the magnet retainer fitting is maintained in strict vertical relation.
