Definitions

  • This invention relates to an electrical switch structure, and more particularly, to such a structure which includes a base or casing carrying one or more electrical terminals.
  • An object of this invention is the provision of such a switch structure, the component parts of which can be rapidly and easily assembled into and retained in operative condition.
  • a further object of this invention is the provision of such a switch structure which is compact, dependable in use, and economical to manufacture.
  • Fig. 2 is a plan view thereof
  • Fig. 3 is a plan view similar to Fig. 2, but with one of the casing members removed;
  • Fig. 4 is a sectional view on a slightly enlarged scale and taken along line 4, 4 in Fig. 2;
  • Fig. 5 is a sectional view taken along line 5, 5 in Fig. 4;
  • Fig. 6 is a sectional view taken along line 6, 6 in Fig. 2;
  • Fig. 7 is a fragmentary sectional view taken along line 7, 7 in Fig. 6;
  • Fig. 8 is a sectional view on a slightly reduced scale and taken along line 8, 8 in Fig. 4;
  • Fig. 9 is a fragmentary sectional view taken along line 9, 9 in Fig. 8;
  • Fig. 10 is an exploded perspective view of the electrical switch shown in Fig. 1.
  • casing members 22 and 24 are secured in interfitting engagement with each other by means of a stem 26 having a head 28,
  • Fastener 30 may be of the well known type manufactured by Tinnerman Products, Inc., Cleveland, Ohio, and includes a pair of jaws 32, 32 which bite into and prevent unintended retraction of the fastener from post 26 when the fastener is pressed thereover to the position shown in Fig 1.-
  • a sleeve 34 formed of a suitable electrically insulating material such as nylon.
  • Sleeve 34 provides flanges 36 and 38, respectively, at its opposite ends for a purpose later to become apparent.
  • a hollow, cylindrical plunger weight 40 formed of a suitable magnetic material such as SAE 1113 steel.
  • a movable, bridging contact member 42 provides an aperture 44 within which sleeve 34 is loosely disposed.
  • Bridging contact member 42 is formed of a suitable, electrically conductive material such as phosphor bronze.
  • a compression spring 46 resiliently biases plunger weight 40 away from the bridg ing contact member 42 and against flange 38 carried by sleeve 34.
  • Spring 46 also resiliently biases bridging contact member '42 against washer 48 which, in turn, is biased against flange 36 provided by sleeve 34 as best shown in Figs. 4, 5 and 10.
  • Sleeve 34, plunger weight 40, bridging contact member 42, spring 46 and washer 48 together form a plunger subassembly 49 which can be pre-assembled before assembling of the remaining parts of switch 20.
  • Terminal 60 is provided with an aperture 64 within which a projection 66 is disposed.
  • Projection 66 is fixedly carried by casing member 24 and extends from the bottom of a guideway 68 (see Figs. 1 and 10) provided by the interfitting surfaces of casing members 22 and 24, extends through aperture 64 in terminal member 60 and into interfitting engagement with a recess in the form of a socket 70 provided by casing member 22. It will be noted that projection 66 facilitates alignment of terminal 60 and casing member 22 with casing member 24 when these parts are assembled together. Also, projection 66 prevents longitudinal movement of terminal 60 within guide way 68.
  • Guideway 68 includes a pair of upstanding side walls 72, 72 which interfit with the respectively adjacent side portions of terminal 60 thereby to prevent substantial rotation of terminal 60 about the axis of projection 66.
  • the bottom of guideway 68 is formed by a surface 74 provided by casing member 24 and the top of guideway 68 is formed by a surface 76 provided by casing member 22, all as viewed in Figs. 6 and 10.
  • Surfaces 74 and 76 interfit with the respectively adjacent portions of terminal 60 and thereby prevent vertical deflection of this terminal as viewed in Fig. 6.
  • terminal 60 is illustrated in the drawing as being connected to a lead in a manner different from that of terminal 62.
  • a ferrule 98 which has been secured about the bared end of a lead 100 is welded to the protruding end of terminal 60.
  • terminal 60 could be provided with a return-bent portion in the same manner and for the same purposes asv that described above with respect to terminal 62.
  • an additional terminal 102' is'shown as being incorporated by switch 20.
  • terminal 102 is provided with a head 104, a portion of which lies in each of recesses 106 and 108, respectively.
  • Recess 106 is provided by casing member 22 and communicates with a slot 110 which extends to the exterior of the casing.
  • Recess 108 is provided by casing member 24 and communicates with a slot 112 which likewise extends to the exterior of the casing.
  • slot 110 extends to the lowermost edge of easing member 22 to permit the assembly of easing member 22 with casing member 24 after positioning terminal 102 within recess 108 and slot 112 of casing member 24. It will be apparent that merely assembly and retaining casing members 22 and 24 with terminal 102 therebetween results, as with terminals 60 and 62, in terminal 102 being fixedly retained in operative relation with the remainder of the switch structure.
  • Terminal 102 may be provided with a slot 114 for the reception of a lead 116 extending from one end of coil 50 as shown in Figs. 1, 2, 3, 4, 6, 8 and 10. Alternatively, the end of lead 116 may be welded to terminal 102', and a separate lead otherwise suitably connected to terminal 102.
  • Casing member 22 provides a pair of projections 120 and 122.
  • Projection 120 interfits within an aperture 124 provided by easing member 24.
  • Projection 122 interfits with a slot 126 provided by easing member 24, which slot opens to one side of this casing memben.
  • a pair of shoulder-providing members 128 and 130 aid in retaining coil 50 about cylindrical portion 132 of casing member v24.
  • Shoulder-providing member 128 includes a relieved portion 134 as shown in Figs. and 10, for the reception of one of the end turns of coil 50.
  • Reference numeral 136 refers to the opposite end of coil 50 from that to which lead'116 is connected.
  • switch 20 may be assembled as follows. First, pin 26 is inserted into casing member 24 to bring the head 28 thereof against the lowermost edge of cylindrical portion 132. Plunger subassembly 49, having been pre-assembled, is then sleeved onto stem 26. The respective widths of aperture 124 and slot 126 in casing member 24 are less than the width of bridging contact member 42whereby unintentional disorientation of the bridging contact member with respect to the rest of the switch 20 is avoided. Terminals 60, 62 and 102 are then assembled with casing member 24 in the positions described above, after which casing member 22 is disposed in interfitting engagement with the previously assembled structure.
