Definitions

  • . /'rea flea/aria Q/ya is UNITED STATES PATENT OFFICE.
  • the invention relates to electric switches of the type generally used in connection with light-installations and fixed against. walls.
  • the invention has for its object a new construction of switches inexpensive to produce both from the ,point of view of material used and workmanship required;
  • the switch comprises parts out out of plates to suitable shape, and capable ofbeing worked in a cold state, without the use of special tools.
  • Figure 1 is a cross section through the switch center-line
  • Fig. 2 is an inverted plan view of same.
  • The' switch comprises a body 1 of insulating material, formed with a cavity composed of three cylinders 161718- of decreasing diameter.
  • the middle cylinder has diametrically opposed wall recesses -19-. 20 is a hole through the center of the body allowmg passage of a spindle or equivalent, -2,
  • said spindle being formed from a plate folded on itself.
  • the upper end of said spindle is provided with a key --3- and the lower end is shaped into arms 4. a
  • Plate 12 has a central circular aperture of suiiicient diameter to permit member 5 to rotate freely therein, while extensions 9 depending from said plate revent any angular movement of said plate.
  • the ends of said extension are pliable and constitute the terminals of the switch; the ends of the line-wire are coiled on said ends, and the latter are folded up to grip said wires, as shown in dotted lines in Fig. 1.
  • butterfly b Upon spindle -2- being turned through 90, butterfly b will be rotated and the wings 14- brought on insulating disk -12- thereby opening the circuit.
  • a wall switch comprising a body formed with a plurality of cylindrical cavities with upwardly decreasing diameter
  • A. wall switch comprising a body formed with a plurality of cylindrical cavities with upwardly decreasing diameter, and a'central hole; a spindle equivalent in said hole, with a key at one end and two arms'at the other end, a forked member fitted on said spindle and seating on said arms, an insulatin g disk, a butterfly plate on said spindle with wings forming part of thebutterfly plate sliding over said insulating disk, a coil spring inserted between said spindle arms and said butterfly plate, two contact plates on said disk, with projecting pliable terminals, and laminated springs to snap said forked member.
  • a wall switch comprising a body formed with a plurality of cylindrical cavities with upwardly decreasing diameter, and a central hole; a spindle equivalent in said hole, with a key at one end and two arms at the other end, a forked member fitted on said spindle and seating on said arms, a metal disk on said arms, an insulating disk, a butterfly plate on said spindle with wings forming part of the butterfly plate sliding over ber, and an insulating disk between said;
