摘要： A rotary switch having a terminal base molded on a lead frame which includes internal contacts and external terminals, along with the connecting straps between them, all formed of a single metal part. Portions of the metal of the lead frame are selectively removed in order to create a variety of switch configurations. Different switch actuating rotors are provided which further allow creation of different switch modes (single throw, double throw, etc.). The rotor is also provided with detents in order to allow for retention and indexing of the switch positions. A ramp may be selectively installed into the rotor to eliminate unwanted detent positions without requiring a different rotor. One or more "floating" movable contact elements complete the circuits when the rotor allows a respective spring to force a floating movable element into contact with both of a corresponding pair of stationary contacts of the terminal base. A separately usable illuminated indicator module is mounted on a bushing surrounding the switch rotor and the knob of the switch transmits light passing from the indicator module to the front of the knob where it can be viewed. The module includes a light distributor which directs the light from a single lamp to several positions corresponding to the switch positions.
摘要翻译：一种旋转开关，其具有模制在引线框架上的端子基座，该引线框架包括内部触点和外部端子以及它们之间的连接带，全部由单个金属部件形成。选择性地去除引线框架的金属部分，以便产生各种开关配置。提供了不同的开关致动转子，其进一步允许创建不同的开关模式（单掷，双掷等）。转子还具有棘爪以便允许保持和分度开关位置。可以将斜坡选择性地安装到转子中以消除不必要的止动位置，而不需要不同的转子。当转子允许相应的弹簧迫使浮动的可移动元件与终端基座的相应的一对固定触点两者接触时，一个或多个“浮动”可动触点元件完成电路。单独使用的照明指示器模块安装在围绕开关转子的衬套上，并且开关的旋钮将从指示器模块传递的光透射到可以看到的旋钮的前部。该模块包括一个光分配器，其将来自单个灯的光引导到对应于开关位置的多个位置。
