  • the grooves which form an important part thereof are not open at both ends, but are open at one end of the main housing.
  • the main base housing is so arranged that while it may conveniently be formed in a cylindrical outer contour, at one end it has an integral outer flange, which is substantially rectangular in contour, and with which there is engageable a closure plate which is substantially secure against dust and dirt penetration therethrough, the outer closure plate being provided with holes through which the contacts from inside the housing may extend, without lessening their protection against dust and dirt penetration.

  • an insert body which may be formed for seating a lamp socket and one or more turnable and also axially movable contaotrings, whereby various types of circuit changes may be achieved.
  • a further advantage of the present construction' is that inasmuch as the auxiliary engageable devices are both axially movable and turnable, there is the possibility and the assurance that the contacts themselves will remain clean and perfectly conductive.
  • the various types of switching arrangements can be constructed, and connections made to the sections of the contact rings, so that contact elements on the interior of the main base, can be brought drical also in contour, and has on its inner surface a number of ribs or grooves 2 formed integrally therewith and extending radially inwardly therefrom, for the seating therein of contact blades or bus wires 3, also seen in FIG. 5, for effecting necessary contact in this device.

  • one or more non-symmetrically located ribs and grooves may be formed in the main base housing 1 and the plug-in device 26, or portions thereof, so that there will be no question as to the angular orientation of the insertion of the plug-in device 6 in relation to the main housing 1. It is conceivable that within the scope of the present invention, the arrangement may be so that the polarization of the various related contacts in two or more poles, may be attained by this type of comparable construction. From FIG.
  • main contact blades or buses 3 are continuous from their outer ends 5 through the grooves in the interior of the main housing 1, and bent in similar fashion as indicated, inwardly and then is shaped with arched inner portions as at 22 to form spn'ngy or resilient contact engaging portions.
