    • The invention relates to an improved contact device suitable especially for use with manual control devices of the pushbutton and rotary types.
      The contact devices comprises an insulating housing containing a contact structure, and terminal connectors extending from the contact structure outwardly of the housing through openings in wall portions thereof, wherein the terminal connectors (173) are substantially Z-shaped, and the housing has interior flanges (183) which, together with wall portions (162) of the housing adjacent the respective openings, define pockets in which intermediate portions (179) of the respective terminal connectors are lodged and retained, the flanges in addition serving as insulating barriers between the said intermediate portions of the terminal connectors and the contact structure (153,155,157).
      The novel arrangement enables the component parts of the contact device to be mounted easily and without hardware, and it prevents electric flashovers or arcing from occurring between current-carrying parts disposed closely addcent each other.
    • 本发明涉及一种特别适用于按钮和旋转类型的手动控制装置的改进的接触装置。 所述接触装置包括一个包含接触结构的绝缘壳体和从所述接触结构体通过其壁部分中的开口从所述壳体向外延伸的端子连接器,其中所述端子连接器(173)基本上是Z形的,并且所述壳体具有内部凸缘 (183),其与壳体的邻近相应开口的壁部分(162)一起限定凹穴,其中相应的端子连接器的中间部分(179)被放置并保持在其中,所述凸缘另外用作所述 端子连接器的中间部分和接触结构(153,155,157)。 该新颖的布置使接触装置的组成部件能够容易地安装而不需要硬件,并且防止在彼此紧密相邻设置的载流部件之间发生电闪电或电弧。
