    • A key attached, for example, to the door of an electrical equipment cubicle is capable of sliding within a passageway so as to cause pivotal displacement of a cam and upward displacement of a push-rod, thus releasing a switch lug. A locking rod forming part of a slide-block which is coupled with the push-rod is capable of moving between a locking position in which an annular channel permits displacement of the key and an unlocking position in which the locking rod is engaged within a key notch. One end of the slide-block projects from the top face of the switching unit head in order to be downwardly displaced by an actuator, whereupon the key can be withdrawn without difficulty or danger.
    • 例如,附接到电气设备柜门的钥匙能够在通道内滑动,从而引起凸轮的枢转位移和推杆的向上移位,从而释放开关凸耳。 形成滑块的一部分的锁定杆,其与推杆联接能够在锁定位置之间移动,其中环形通道允许钥匙的移位和锁定杆在钥匙内接合的解锁位置 缺口。 滑动块的一端从切换单元头部的顶面突出,以便由致动器向下移位,从而钥匙可以毫无困难或危险地撤回。

    • A small electrically operated valve in which a control solenoid sub-assembly is mechanically associated in a non-dismantleable fashion by means of a face with the corresponding face of a pneumatic switching sub-assembly having a valve member. Each of the two sub-assemblies is of plastics material and comprises passage portions which may be brought into aligned relationship to form at least one aligned passage capable of receiving at least one small cylindrical metal pin, a first end thereof being positioned below the surface at which the entry of the aligned passage opens, while the other end is in the vicinity of a metal protective portion which is positioned inaccessibly in either one of the two sub-assemblies and which is disposed substantially transversely to the axis of said aligned passage.
    • 一种小型电动阀,其中控制螺线管子组件通过具有带有阀构件的气动切换子组件的相应面的表面以不可拆卸的方式机械联接。 两个子组件中的每一个都是塑料材料,并且包括通道部分,该通道部分可以对准关系,以形成能够容纳至少一个小圆柱形金属销的至少一个对准的通道,其第一端位于表面下方 对齐的通道的入口打开,而另一端处于金属保护部分附近,该金属保护部分不可接近地定位在两个子组件中的任一个中并且基本上横向于所述对准的通道的轴线设置。
