Definitions

  • This invention relates to electric switches of the push-button type.
  • An object of this invention is to provide a pushbutton switch which in the present instance embodies pairs of opposed contacts with a bridging element between the contacts and with the latter floatingly mounted for positioning between either pair of contacts and movable from one pair of contacts to the other by means of a spring which is tensioned by movement of a push button.
  • Another object of this invention is to provide aswitch of this kind embodying a rocking bridging member and a spring for laterally shifting the bridging member as the latter is rocked or tilted.
  • a further object of this invention is to provide a switch of this kind wherein the spring for laterally shifting the bridging member will auto matically reset the bridging member for movement in the opposite direction.
  • FIG. 1 is a detail side elevation, partly broken away, of a switch constructed according to an embodiment of this invention
  • Figure 2 is a detail end elevation of the device.
  • the numeral ll designates a base which is preferably formed of insulating material and which has secured thereto an upstanding body 2 also formed of insulating material.
  • a pair of contacts 6 and 'i are disposed at one end of the body 2 in a position above the base and a second pair of contacts 8 and 9 are disposed in opposed relation to the contacts and 1 at the opposite end of the body 2.
  • a bridging element 3 of U-shaped configuration in transverse section loosely engages over the body 2 and is provided at the ends of the parallel sides thereof with spaced fingers or lugs ii! and I I. These lugs or fingers In and H are rounded at their lower ends and the bridging element 2 is adapted in one position thereof to be disposed in a position between one pair of the contacts such as contacts 8 and 9 and in the other position thereof to be disposed in bridging relation between the contacts 6 and I.
  • a pair of springs 4 and 5 are secured to the bridging element 3 in substantially the center between the ends thereof, and at the upper end of the bridging element 3 and are secured at their opposite ends to the base 11. These springs 4 and 5, as shown in Figure 1, will be inclined to the vertical in any position of the bridging element 3 so that the latter will be biased to movement in the opposite direction when the bridging element 3 is elevated as will be hereinafter described, to provide for lateral movement thereof.
  • the bight of the bridging element 3 is formed with a pair of spaced detents or recesses I 2 and I 3 in a selected one of which the pointed end of an insulating operating rod or bar I is adapted to engage. As shown in Figure l,
  • the insulating body 2 is formed adjacent the base I! with abutments I5 and it which are adapted to be initially engaged by one of the fingers II] or H, depending on the position of the bridging member 3.
  • An intermediate abutment I4 is disposed between the abutments I5 and I6 and is adapted to prevent lateral movement of the bridging member 3 while at the same time permitting rocking movement thereof when the bridging member is elevated by inward movement of the operating member I.
  • a switch comprising opposed pairs of contacts, an insulating body between said contacts, a bridging member U-shaped in transverse section loosely engaging over said body, a spring connected between said body and the central portion of the bight of said member, said body having a pair of recesses in the blght thereof on opposite sides of said central portion, outer abutments fixed relative to said body and selectively engageable with said member, an intermediate abutment carried by said body medially between said pair of abutments, pairs of arms carried by the sides of said member selectively engageable with said abutments, and an endwise movable operator slidably carried by said body engageable alternately in said recesses whereby to rock said member to lift said arms over an outer abutment, said spring upon rocking of said member shifting
