Definitions

  • the invention relates to a new switch for electrical installations, as for example electric light and the like, which differs greatly from, and is much superior to, known devices of this kind inasmuch as it consists of a comparatively small number of separate parts which may be joined to each other or assembled without the use of screws.
  • the object of the invention is to remove these drawbacks. This is accomplished by inserting the wires connected to the switch in metal pieces that are embedded in a plate of insulating material. Connections are established in the known manner between corresponding wires in accordance with circuit requirements by a movable metallic bridging piece. Thls bridging piece is pressed down upon the parts or contacts beneath as firmly as necessary by a spring. The wires connected to the switch are held in position without employing screws by a clamping ring which is forced down on the periphery.
  • this clamp-- ing ring may be arranged to be pushed over the edges of the plate and furnished with an external thread. If a corresponding internal thread is then provided in the switchbridgin time. And the elasticity of the bridging.
  • the clamping ring may be made to serve for the additional purpose of holding the cover.
  • the connecting or bridging piece is moved from contact to contact in the well known manner by a revoluble shaft, upon a four cornered section of which the bridging piece is fixed, i. e. the part of the shaft that is inside the hole of the brid ing piece is made rectangular or square. y a spring situated between the switch-cover and the piece this latter is pushed down with a equate pressure against the switch base.
  • the contacts are provided at the top with furrows into which the rubbing portions of the bridging piece. are adapted to fit.
  • the shaft or spindle carrying the bridging piece is journaled in the insulating base and may protrude through the base and be held in position by a suitable fixing means beneath the base, or it may be let into the base without passing through it.
  • Fig. 2 a section through Fig. 1 on the line IIII
  • Fig. 3 a section through Fig. 1 on the l1ne III-III and Fig. 4 a vertical section through a second type of switch.
  • the switch consists of a base plate 1 in which metal parts or contacts 2 are embedded or inserted in suitable channels.
  • the metal parts 2 have holes running lengthwise in which the wires 3 are inserted.
  • the outer ends of the wires are held fast and the wires thus kept in position by a clamping ring 4 which is pushed over the rim of the base plate 1.
  • Connections between corresponding contacts 2 are established by a metallic bridging piece 5.
  • This bridge 5 is mounted on the four-cornered portion of the shaft 6 which is adapted to be turned by the handle 7
  • the shaft or spindle Gpasses through the switch cover 8 which may be held in position in the well known manner by the handle 7.
  • a spring 9 is placed which presses't e bridge down against the base.
  • each part 2 is shaped as shown in Fig. 3, i. c. it is formed with a furrow in WhlCh the bridge clenches.
  • the spindle 6 is journaled in the base-plate l and is held in any suitable manner, as for example by a nut 10 or a bur.
  • the clamping rin 4 is slipped on f om below and provide with an external thread 11. Onto this thread a corresponding female screw in the cover may be screwed. If the switch is made in this manner the spindle 6 need not ass through the baseplate. It'will be su cient to.lodge it deep enough in the base to secure a 'sufliciently stron bearing. It may also be mentioned that in this type of switch the cover 8 is not held in place by the handle 7.
  • a switch for electric circuits comprising a base of insulating material with channels therein, metal pieces with holes in the directions of their lengths for the wires of the circuits, said metal pieces being inserted in the said channels, and a bridging piece for establishing connections between the said metal pieces.
  • a switch for electric circuits comprisin v a base of insulating material with channe s therein, metal pieces with holes infthe directions of their lengths for the wires of the circuits, said metal pieces being inserted in the said channels, a bridging piece for establishing connections between the said metal pieces, and a clamping ring fitting over the (rim of the said base for holding the said wires in position.
