Definitions

  • PAUL J. SCHOPHUIZEN United States Patent 2 Claims. ((l. zoo-51 The invent-on relates to a socket-switch combination for battery and, alternatively, automobile cigarette lighter operation of a dry shaver.
  • the switch parts of the combined socket and switch turns the shaver on and off regardless of Whether the shaver motor is powered by battery or via a cord inserted in the socket.
  • a plu-gswitch of the general type is known from German Patent No. 123,043 dated November 1, 1927.
  • the principle object of the invention is to provide such a device which requires a minimum of space and can be inexpensively manufactured.
  • the socket is of the coaxial plug type having an outer contact tube concentric within a substantially disc-shaped, rot-atably journalled switching member of insulating matcrial.
  • a toggle action spring is provided to hold the switch in ts switched positions.
  • a flat switching contact is provided on the switch disc at right angles to the axis of rotation and cooperates with fixed contact springs connected to the base plate of the socket-switch member.
  • FIG. 1 is a plan view, partly in cross-section, of a socket-switch according to the invention.
  • FIG. 2 shows the device of FIG. 1 in a sde-elevation view and partly in an axial cross-section.
  • FIG. 3 is an inverted plan view of the underside of the device seen in FIG. 1.
  • the device shown in the drawing is provided, preferably in the manner shown, on an insulating base plate 1, for example, consisting of hard paper, having an aperture which consists of a substantially circular part 3 and joining thereto a lateral aperture extension 5.
  • the aperture 3, is for the greater part covered by an insulating carrier plate 7, for example, consist-ing of a synthetic resin (see FIGS. 2 and 3) which is connected to the base plate 1 by means of two flanged eyelets 9 and 11. Plate 7 does not cover aperture extension 5 however.
  • the carrier plate 7 supports a coaxial plug contact consisting of a centra] pin 13 and a contact tube 15 coaxially surrounding the -pin 13.
  • the central contact pin 13 is provided with a collar 17 and at the rear end (in FIG. 2 the top end) with a bent flange 19 which connects the pin to the base plate. Bctween the pin collar 17 and the base plate 7 are clamped successively, an insulating ring 21, the apertured bottom 23 of the contact tube 15 (in FIG. 2 the upper edge), and a metal connection strip 25, all on one side of the carrier plate 7.
  • shaped switching member 31 consist-ing of insulating material, f-or exarnple synthetic resin, is rotatably journalled.
  • a flat contact 33 On the side of the disc-shaped switching rneber 31, facing the base plate 1, is a flat contact 33 in a plane at right angles to the axis of rotation. Contact 33 cooperates with two strip-shaped contact springs 35 and 37 which are approximately in alignment. The ends of contacts 35 and 37 are rem-ote frorn one another and are hooked into apertures 39 and 41 of the base plate 1 and are held in these apertures by tags 43 and 45 respectvely projecting into the apertures 39 and 41.
  • the coaxial plug contact consisting of pin 13, tube 15 and the tubu-lar shaft 47 of the disc-shaped switching member 31 are at least partially within the circular part of the aperture 3.
  • Shaft 47 of switching member 31 has a radial extension 49 (sec FIG. 1) in the form of a rib which is arranged in parallel with the shaft 47 and has an end projecting beyond shaft 47 in the direction of base plate 1 (in FIG. 1 directed backwards).
  • the free end of projection 49 engages one end of a toggle action spring 51 provided in the aperture extension 5.
  • the other end of that spring is connected to a tag 53 projecting in to the opening 5.
  • the switching member 31 has two stable switched postions, one of which is shown in FIG. 1.
  • the position of the contact member 31 is that in which the contact springs 35 and 37 are not connected together.
  • the ether end of strip 57 is connected in an aperture 59 of the base plate 1 in a manner simlar to that of the contact sprngs 35 and 37.
  • the contact tube 15 of the coaxial plug contact is connected via the connection strip 25 and eyelet 11 to a similar connection strip 61 at one end.
  • the ether end of strip is fastened to plate 1 similar to the connection strip 57.
  • Strip 61 also serves as a soldering tag.
  • plug socket-switch combination is useful with any battery powered device which may also operate trom another source of energy via a plug-in conductor.
