Abstract

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 adjacent each other.
