    • A foot-pedal switch for electrically connecting two conductors includes a conductive base plate connected to one of the two conductors and having a bottom surface for resting on a horizontal surface, a rear end having a first portion of a hinge assembly, at least one non-conductive spring, and a first conductive contact point at a front end thereof. A conductive top plate is connected to the other conductor, a rear end having a second portion of the hinge assembly, and a second conductive contact point at a front end thereof. A non-conductive hinge pin assembly pivotally connects the first and second portions of the hinge assembly mutually and non-conductively together. The top plate rests on the springs such that the first and second contact points are electrically and mechanically separated until pressure is applied to the top plate to deform the springs until the contact points electrically connect.
    • 用于电连接两个导体的脚踏开关包括连接到两个导体中的一个导体并具有用于搁置在水平表面上的底表面的导电基板,具有铰链组件的第一部分的后端, 导电弹簧,以及在其前端的第一导电接触点。 导电顶板连接到另一导体,后端具有铰链组件的第二部分,在其前端具有第二导电接触点。 不导电的铰链销组件将铰链组件的第一和第二部分相互和非导电地枢转地连接在一起。 顶板搁置在弹簧上,使得第一和第二接触点电气和机械分离,直到压力施加到顶板以使弹簧变形,直到接触点电连接为止。

    • A drumstick holder, comprising: a member providing a surface; one or more retaining members (for example clips arranged to grip a drumstick) arranged to prevent or restrict free movement of a drumstick across the surface; a plurality of protrusions from the member; wherein the drumstick holder is adapted for fitting to a rim of a drum or further comprises means for fitting the member to a rim of a drum (for example a clamp); and when the drumstick holder is fitted to a drum rim, each respective protrusion engages a drum at a different respective position around a circumference of a drum rim. The surface may be substantially planar. The drum may be a bass drum.
    • 鼓槌保持器,包括:提供表面的构件; 布置成防止或限制鼓槌穿过表面的自由运动的一个或多个保持构件(例如夹持鼓槌的夹子) 从所述构件的多个突起; 其中所述鼓槌保持器适于装配到滚筒的边缘,或者还包括用于将所述构件装配到滚筒(例如夹具)的边缘的装置; 并且当鼓鼓保持器安装到鼓轮边缘时,每个相应的突起在围绕鼓边缘的圆周的不同的相应位置处接合滚筒。 表面可以是基本上平面的。 鼓可以是低音鼓。
