    • An optical disk apparatuses includes a turntable with a bearing surface, and a spindle motor for rotating the turntable. The spindle shaft has a cylindrical first shaft having an upper end flush with the bearing surface, and a second shaft having an upper end portion and arranged in the first shaft to be slidable between an engaging position in which the upper end portion projects from the upper end of the first shaft to engage a center hole of an optical disk placed on the bearing surface and a depressed position in which the upper end portion is recessed from the upper end of the first shaft to be disengaged from the optical disk. The second shaft is moved by a spindle moving mechanism from the first position to the second position when the optical disk is to be loaded on and unloaded from the turntable.

    • A miniature switching unit including two fixed contact pieces arranged one above the other and fixed to terminals, respectively, and a movable contact piece. Each of the fixed contact pieces is made of springy wire members and includes parallel portions having equal inner distances, respectively. The movable contact piece in the form of a rod having a thickness slightly larger than the inner distances of the parallel portions of the fixed contact pieces and includes an intermediate insulator, an upper conductor axially, concentrically and integrally connected to the upper end of the intermediate insulator and a forward conductor axially, concentrically and integrally connected to the lower end of the intermediate insulator. The movable contact piece is held in a housing so as to be positioned in and contacting the parallel portions of the first and second fixed contact pieces and movable in a manner that the intermediate insulator moves across any one of the first and second fixed contact pieces, which are arranged one above the other.
    • 一种微型开关单元,包括分别彼此并排设置并固定到端子的两个固定接触片和可动接触片。 每个固定接触片由弹性线构件制成,并且包括分别具有相等的内部距离的平行部分。 杆的形式的可动接触片的厚度稍大于固定接触片的平行部分的内部距离,并且包括中间绝缘体,与中间体的上端轴向同心并且整体连接的上导体 绝缘体和正向导体轴向,同心且整体地连接到中间绝缘体的下端。 可移动接触片被保持在壳体中,以便定位在第一和第二固定接触片的平行部分中并且可接触第一和第二固定接触片的平行部分,并且可以以中间绝缘体移动穿过第一和第二固定接触件中的任何一个的方式移动, 它们彼此排列。
