Definitions

  • My invention relates to improvements in electrical switches of the push-button type in which only one button is employed; and the object of my improvements is to simplify the lswitch structure.
  • Fig. 1 is a side elevation of the invention, partly in section; Figl 2, a top view; Fig. 3, a second side View; Fig 4, a mechanical detail; Fig. 5, a rear elevation of the contact elements; and Fig. 6, a partial side elevation, showing the bearing disposition of the pivoted contact shaft.
  • a panel plate 3 and a plate 2 are mounted parallel upon an insulating board I and form the two standards for the rotatable contact shaft 4 (Fig. 6). of square section and is provided with an insulating cover and two round end journals, one of which projects from the said plate 3.
  • a lever 5 is fastly attached to the said latter journal and comprises two opposite arms 5a and 5h, and between the latter a third arm 5c extending Adownwardly (Fig. 1).
  • a stud pin is passed through the said arm 5c and forms a journal on both sides of the latter.
  • a slotted fork 6, provided with a bar bears on the said latter journals. Between the fork 6 and a collar 'I a compression spring 9 is confined upon the bar of the fork.
  • a bell crank 8 at its fulcrum is pivoted on a bolt which is secured to the plate 3.
  • the lower or horizontal arm of the lever 8 is forked and journalled to the collar 'l (Fig. 4).
  • the upper arm of the lever 8 is articulated to two lateral push bars I and II.
  • the other ends of the latter are pivoted to a roller I2 which in turn is journalled to the lower ends of two parallel connecting rods I3 and I4.
  • the upper ends of the latter are pivoted to the said arm b.
  • roller arm I5 Two superimposed rollers are rotatively mounted upon one end of a roller arm I5, and the lower of these rollers rests upon the said lever 5. In place of this latter roller one also could use a slide element.
  • arm I5 is journalled toa lever I6 which in its lower part is provided with a slide plate upon which the said roller I2 is movable.
  • 'Ihe lever I5 is pivoted to a pin passing through the center of the said slide plate and secured to the '4 plate 3.
  • a stud I'l which limits the movement of the lever 5, is situated between the arms 5a and 5c of the latter and fastened to the plate 3.
  • a key I8 is positioned above the roller arm I5 and is The latter is The other end of the said pivoted to a bolt ⁇ secured to the plate 3.
  • the said key I8 rests upon the upper roller of the roller arm I5, and its free end is situated below an angle element I9 which is inserted between a set collar of a spring rod 20 and a push button 2I fastened thereto.
  • the said spring rod 2!! is displaceably guided by means of a bracket 22, which is fastened to the plate 3, and the push button 2l, which latter itself is axially guided in the housing cover of the switch.
  • a compression spring 23 is confined upon the rod 20 between the said bracket 22 and the said set collar.
  • the said key I 8 suitably may be passed directly through the switch housing, and it also may be provided with a foot release which is not shown in the drawings.
  • contact elements are secured to the contact shaft
  • a Spring contacts are disposed on either side of the said elements which may be engaged with or disengaged from the latter by turning the contact shaft 4.
  • the number of contacts depends on the number of circuits employed. rI'he contact shaft 4 also may be provided with an indicator scale made visible through a sealed opening in the housing cover of the switch.
  • the switch according to my present invention possesses only one operating button, and since one cannot tell ohand if the switch be in the onor off-position, I recommend the provision of an indicating device.
  • a plural-pole single-throw switch of the character described comprising a frame, a contact shaft pivoted therein, a three-arm lever secured to said shaft, a stud secured to said frame for limiting the rocking of said shaft and lever, a connecting rod at one end articulated to the center arm of said lever, a bell crank pivoted in said frame and having two arms at right angles to one another, a collar journalled to one of the latter arms wherein the said connecting rod is longitudinally displaceable, a helical spring wound upon the said rod and bearing against said center arm and said collar, a pair of push bars at one end journalled to the other arm of said bell crank, a roller journalled to the other end of said bars, a pair of connecting rods at one end pivoted to said roller and push bars and at the other end journalled to one of the lateral arms of said lever, a second lever pivoted in said frame and having a slide face on both sides of its fulcrum for the said roller, an arm pivoted to the one end of said second lever and at its
