摘要： A terminal seal for an environmentally sealed electric switch is reduced in cost while maintaining an effective seal by eliminating the O-ring and instead angularly reshaping the lower annular surface (20d) of the stationary contact head (20c) and the lower annular surface (28d) of the contact support rivet (28) to coact with the reversed radii (R1, R2) surface of the terminal hole (14, 18) in the molded nylon base (2). Such coaction, when the stationary contact (20) or the contact support rivet (28) is clamped in place and riveted to the external terminal (24, 32), causes cold flow of the radius (R1) along the reshaped angular surface (20d, 28d) to provide an effective seal without the need of an O-ring or other packing material or cement.

摘要： A silicone seal is molded-in-place to a frame and toggle lever pivotally mounted in the frame, the seal integrally providing a closed loop bead gasket on the lower surface of the frame surrounding the periphery of a switch cavity at the upper surface of a base. Lamp sockets are formed through the base and frame outside the closed loop gasket surrounding the switch cavity, the sockets being surrounded by additional closed loop gaskets integral with the seal, and further comprising lamp receiving resilient boots integral with the seal disposed in a front opening pocket of the frame for convenient insertion/removal of lamps from the front of the switch. A rocker button snaps onto a stub end of the toggle lever within the pocket to overlie the lamps, the button being provided with one or more windows and selected indicia. A panel gasket is molded-in-place to an under surface of a peripheral flange on the frame in the same molding operation as the aforementioned seal, and may also be an integral part of the seal.
摘要翻译：将硅树脂密封件模制到可枢转地安装在框架中的框架和肘节杆的位置，所述密封件在框架的下表面上一体地提供封闭的胎圈垫圈，围绕在框架的上表面处的开关腔的周边基础。灯座通过位于开关腔周围的封闭环垫圈外部的基座和框架形成，插座由与密封件成一体的另外的闭环垫圈包围，并且还包括接收弹性靴子的灯，其与设置在前开口袋的框架，方便从开关前部插入/取出灯。摇杆按钮卡入口袋内的肘杆的短截线以覆盖灯，该按钮设置有一个或多个窗口和选择的标记。在与上述密封件相同的模制操作中，面板垫圈被模制到位于框架上的周边凸缘的下表面上，并且也可以是密封件的组成部分。

摘要： A reduced size pushbutton (6) switch having a plurality of contact pairs (40, 42, 44, 46) arranged angularly for radial actuation by normally-open cams (34c) or normally-closed cams (34d) on a vertically reciprocated actuator block (34) by a snap-action mechansim (30c, 30d, 36, 38 or 66, 68a). The contact pairs are electrically connected to a control circuitry PC board (52) which provides an output control as well as controlling a multi-character alpha-numeric display mounted within the pushbutton. This display includes a light source (22), a display (24) and movable (14) and stationary (12) contacts connecting the light source to a display drive PC board (10) which may be connected to the control circuitry PC board to afford control of the display by some of the contact pairs. A seal (8) between the front panel and the display PC board hugs the pushbutton to prevent dirt from entering the switch base (54).
摘要翻译：减小尺寸的按钮（6）开关具有多个接触对（40,42,44,46），所述多个接触对（40,42,44,46）被成角度地布置，用于在垂直往复致动器块上的常开凸轮（34c）或常闭凸轮（34d）进行径向致动（30c，30d，36,38或66,68a）的快速动作机构（34）。触点对电连接到控制电路PC板（52），其提供输出控制以及控制安装在按钮内的多字符字母数字显示器。该显示器包括将光源连接到显示驱动PC板（10）的光源（22），显示器（24）和可移动（14）和固定（12）触点，显示驱动PC板（10）可以连接到控制电路PC板通过一些接触对来控制显示。前面板和显示板之间的密封件（8）拥抱按钮，以防止灰尘进入开关座（54）。
