    • A seismosensitive element includes a housing formed from an electrically conductive material and having an inclined face formed on the bottom thereof to gradually rise concentrically outwardly substantially from a center of the inner bottom face, and a header fixed to the housing to close its open end and having through-aperture in which an electrically conductive terminal pin is fixed in an insulated relation. A contact is fixed an end of the terminal pin located inside the housing and has a plurality of feather portions disposed concentrically with the terminal pin, the feather portions having a predetermined elasticity. An inertia ball is enclosed in the housing to be located substantially at the center in the housing in a normal position of the element in a stationary state. The inertia ball rolls when subjected to oscillation, so that the inertia ball slides on the feather portions of the contact except for distal ends of the feather portions such that the inertia ball electrically conducts between the contact and the housing and such that the feather portions are elastically deformed, thereby receiving a force causing the same to be pushed against the bottom of the housing. An acceleration responsive switch includes a receptacle including a housing having a conical face, an inertial ball in the receptacle, and an oscillation damping liquid in the receptacle. The oscillation damping liquid has a viscosity such that the inertial ball terminates rotation when it is subjected to an external oscillation to be rotated.
    • 地震敏感元件包括由导电材料形成并具有形成在其底部上的倾斜面的壳体,其基本上从内底面的中心逐渐同心地向外升起,并且固定到壳体以将其开口端部闭合, 具有通孔,其中导电端子销以绝缘关系固定。 接触件固定在壳体内部的端子销的端部,并且具有与端子销同心设置的多个羽毛部分,羽毛部分具有预定的弹性。 惯性球被封闭在壳体中,以在固定状态下的元件的正常位置中大致位于壳体的中心。 惯性球在受到振动时滚动,使得惯性球在羽毛部的远端除了接触部的羽毛部分之外滑动,使得惯性球在接触和壳体之间电导通,使得羽毛部分 弹性变形,从而接收使其相对于壳体的底部被推压的力。 一种加速度响应开关包括一个插座,它包括一个具有圆锥面的壳体,该插座中的一个惯性球,以及该容器中的振荡阻尼液体。 振动阻尼液体具有这样的粘度,使得当惯性球经受外部振荡以旋转时终止旋转。
