    Abstract: A plurality of modular contact units are adapted for attachment to a housing containing an operating means which may be of either the push-button or selector switch variety. Each contact unit comprises a single pair of contacts and indicating means to display the condition of the pair of contacts. Camming means may be interchangeably attached to the operating means externally of the switch units. Selector switch operation provides maintained switching for up to eight positions, momentary switching, or momentary-maintained switching. Selector switch cams may be double stacked to provide a maximum number of switching programs with a minimum number of parts. The operating means may be illuminated or non-illuminated and is adaptable for use as a pilot light or a push-to-test unit.

    Abstract translation: 多个模块化接触单元适于附接到包含操作装置的壳体,该操作装置可以是按钮式或选择开关类型。 每个接触单元包括一对触点和用于显示该对触点的状态的指示装置。 凸轮装置可以互换地连接到开关单元外部的操作装置。 选择开关操作提供多达八个位置的保持切换,瞬时切换或瞬时保持的切换。 选择开关凸轮可以双重堆叠,以最少数量的部件提供最大数量的切换程序。 操作装置可以是照明的或不被照明的,并且适用于作为指示灯或按压测试单元。
