Definitions

  • This invention relates to a switch arrangement for electric light installations and the like.
  • FIG. 1 shows the switch arrangement consisting of a switch and of an operating mechanism positively connected with the switch and working without current.
  • Fig. 2 is a section through the switch on line A-A of Fig. 3.
  • Fig. 3 is a cross section of the switch.
  • Fig. 4 shows in section one of the operating mechanisms for the switch.
  • the switch arrangement comprises a switch 1, which has a casing with lid, in which casing a feed disk 2 is keyed on an axle 2.
  • the axle 2 is pivotably mounted in'the bottom plate of the casing and carries on its upper end a contact block
  • the disc 2 has a groove 23 and cams 24:.
  • pull-elements 12 are located which are at tached at one end'to a common pin 3 designed to engage behind one of the cams 24 of disk 2.
  • the pull elements 12 are guided in the switch casing each over a pulley 8, 9.
  • a spiral spring 1 is attached to the pin 3 and fixed at its other end to the casing. This spiral the pin 3 with the pull elements.
  • the contact block 15 is rotatable between two contact springs 13, 1d of terminals 6, 7 insulating' pieces 15 being fixed in two opposite sides of said contactblock. When the axle 2 is rotated the contact surfaces and the insulating surfaces 15 of the contact block are alternately brought into contact with the contact springs 13, 14: so that the circuit is closed and interrupted.
  • the pull elements 12 are preferably enclosed inflexible tubes 22 and connected each to an operating mechanism 16 which works without current.
  • Each operating mechanism comprises a casing closed by a lid 26.
  • a bracket 21 in said casing a two armed lever is pivotably mounted which is composed of the arms 19* and 19".
  • a spiral spring 20 is attached the other end of which is fixed on the bottom plate of the casing. The spring 20 tends to pull the arm 19 towards the bottom plate of the easing, the arm 19 being thus pressed against.
  • a shaft of a push 10 This push 10 is controlled by a spring 17 and located in a bore of lid 26.
  • the spring 17 is enclosed between spring 4 has the tendency to pull towards it a plate 27 which closes the bore inthe lid and a collar. on the shaft of push 10.
  • This spring 18 pushes the shaftof the push 10 upward in the direction of the arrow.
  • To the arm 19 the end of one of the pull elements 12 is attached after. it has been guided around a pulley 18.
  • the flexible tubes 22 enclosing the pull elements are fixed in convenient bores in' the walls of the casing of the switch end or" the casing 25.
  • the switch mechanism operates as follows. If the push 10 is depressed against the action of the spring 17 the two-armed lever 19 19 is oscillated. The pull element 12 attached to the arm 19 of the lever is pulled so that the feed disk is rotated of a quarter revolution, the spring being put under tension at the same time. As soon as the push 10 is released the springs 20, 17 of the operating mechanism make the elements 10, 19 19 return into their initial positions. The spring 1 can expand and moves the pin 3 until it grips behind the next following cam 24 of the disk 2, the pull element 12 being pulled by said pin. If one of the operating mechanisms16 is operated again a quarter revolution of the disk 2 is caused so that the circuit, in which the terminals 6, 7 are inserted can be interrupted and closed at once.
  • pull elements are merely guided over pulleys, it however the flexible tubes 22 are used the pull elements may be guided by spherical elements 11 of known type at the points where the direction of the pull elements has to be altered.
  • the switch arrangement is specially adapted for staircase lighting, or in all cases where one or several electric switches have to be operated from different points.
  • An electric rotatable switch comprising in combination a central switch axle, a notched disc on said shaft, a transverse pin adapted to act upon the teeth of said notched disc, a pull spring holding said transverse pin in its inoperative position, a number of currentless switch boxes, ii push button each switch boX, it pull eleinnt frolh each switch box attached to said transverse pin, and an diateelement for exert ng pull upon said pull element at the depression of the corresponding push button to make said transverse pn impart a part rotation to saidnotched disc. 7
