  • Each actuator is comprised of a rectangular body 12, a wall 14 having an opening 16 located in projection 17 of wall 14, the opening 16 containing therein a mechanical actuator member 18.
  • Each rectangular housing has locked to it on a side opposite wall 14, a printed circuit board or the like 20, such board 20 containing printed circuitry 22 on a first surface thereof.
  • the board 20 has projections 24 on the edges thereof, such projections adapted to matingly lock into slots 26 in sidewall of rectangular member 12.
  • a reinforcing plate 28 generally of metallic structure, has located thereon projections 30 which are adapted to be received by slots 26 in housing member 12. Protection is thereby afforded to printed circuit board 20 against inadvertent breakage or bending.
  • FIGS. 2, 3, 4, and 5 Shown in FIGS. 2, 3, 4, and 5, is one embodiment of the invention, which is designed for momentary on, center-off, with spring bias to the off position.
  • FIGS. 3 and 4 show additional section views of the embodiment of FIG. 2.
  • the opening 16 has a first two opposed surfaces 32, 32, and a second two opposed surfaces 34, 34.
  • Each surface 34 has an outer end portion 36, which extends from surface 34 at an angle thereto, and is normal to the first two opposed surfaces 32, 32.
  • Integral with projection 17 and extending inwardly thereof, are a pair of opposed flexible retaining fingers 40, each having arcuate lips 42 located thereon.
  • Each retaining finger 40 has in facing relationship, and adjacent the end portion 44 thereof, a flat camming surface 46.
  • a finger-engaging portion 48 Located at the outer end of actuator 18, is a finger-engaging portion 48, adapted to be engaged by the fingers of a hand of a human operator.
  • Located intennediate the ends of the actuator 18 are a pair of flat parallel faces 50, which are adapted to mate or be in engagement with the first two opposed surfaces 32, 32, respectively.
  • a first pair of shoulders 52, 52 which are cylindrical, are provided to matingly engage with cylindrically relieved portions 38, 38.
  • Each parallel face 50 has an outward extension 54, having a beveled surface 56'thereon. The outward extension forms a rib which, upon pivotal movement of actuator 18, will come into engagement with the outer end portions 36 of faces 34.
  • outer face portions 36 respectively act as stop means to limit the travel of the actuator 18.
  • the beveled surface 56 is provided to facilitate insertion or assembly of the actuator from the interior of wall 14, such beveled surface engaging camming surfaces 46, 46, and forcing the retaining fingers apart, thereby allowing insertion of the actuator 18.
  • the retaining fingers, and specifically arcuate lip portions 42 will snappingly engage with a second pair of shoulder portions 58, 58, located on the actuator 18.
  • the mechanical actuator 18 has an elongated end portion 60, which is adapted to be received in an apertured portion 62 of carriage member 64.
  • carriage member 64 as is housing 12, are made of a suitable electrically insulating material, such as nylon or polypropelene.
  • the housing 12 and the carriage member 64 need not be made of electrically insulating material.
  • Bus bar 68 has integral therewith a plurality of contact portions 70, which are comprised of cantilevered fingers 72 having curved end portions 74 which end a short distance from bus bar 78.
  • bus bar 68 is carried by and rides on, flanges 76, located on opposite walls of housing 12.
  • camming surfaces 78 are provided integral and spaced from flanges 76. With the built-in resiliency of the sidewalls of housing 12, the edges of bus bar 68 will engage the camming surfaces 78 and force the walls outwardly until the flanges 76 snap into engagement with a first face 80 of bar 68.
  • the bus bar 68 has located on its upper surface or second face 82, detents 84 (see FIG. 5). As seen in FIGS. 2 and 4, extending downwardly from wall 14 are crossmembers 86, which extend between two opposite walls of housing 12 with each crossmember having integral therewith a hollow cylindrical projection. Contained within each cylindrical projection 88 is a helical spring 90, having one end in engagement with the upper wall 14, and the other end in engagement with a ball 92, preferably made of a hard material such as steel or the like. Each ball 92 is biased against the first face 82 of bus bar 68 and, upon appropriate sliding motion of bus bar 68, will cooperate with detents 84 to aid in positioning the bus bar in a predetermined position.
  • the ends 94 of carriage member 64 have cylindrical cavities 96 therein, which cavities receive a helical spring member 98, the free ends of which springs abut against opposite walls of housing 12.
  • the mechanical actuator 18 is biased to a neutral position which is normal to the wall 14.
  • Such position is a center-off position, and pivoting the actuator 18 in either direction will place the switch in the on position.
  • the springs 98 will neutralize their bias, thus returning the actuator to a neutral position.
  • FIG. 6 there is seen a somewhat different embodiment, showing an electrically conductive bus bar 100, carried by carriage member 64.
  • this embodiment are three pairs of detents 102, which allow for either position to be off with the other two positions being varying degrees of on.
  • helical springs 98 have been omitted, thus allowing the switch to remain in any of the three positions in which it is placed.
  • bus bar 104 is adapted for a switch having two positions, on and off. As depicted, with balls 92 shown in phantom, the bar is in a center-off position. The bar can be actuated only in one direction, as shown by the arrow, and movement past the neutral, center-off position, is prohibited by the use of a cylindrical slug 108 which is received in the cylindrical cavity 96 of one end of carriage 64. With actuator 18 in the center-ofi position, the end of slug 108 will abut against the appropriate wall of housing 12.
  • This particular bus bar 104 has four contacts located thereon. As can be seen in FIGS. 2, and 4-7, a vertical rib member on one wall of housing 12 cooperates with a cutout portion 112 in each bus bar for purposes of facilitating the correct positioning of the bus bar upon insertion of the bus bar into the housing 12.
  • gasket material may be employed to prevent ingress of dust and foreign particles into the housing 12.
  • gasket material 114 of a suitable insulating material, would also be desirable wherein an electrically conductive housing is used to insulate the housing from the circuitry on the board.
  • pivotal movement of mechanical actuator 18 will induce appropriate sliding motion of bus bar 68, as indicated by the arrows in FIGS. 5-7, and therefore fingers 72 thereon, to slide fingers 72 onto, or off, of the appropriate circuitry 22 on printed board 20, thus making and breaking electrical contact therewith.
  • the ends 74 of fingers 72 are slightly spaced from bus bar 68 and, upon assembly of the board to housing 12, will abut bus bar 68 before overstress of the contacts 70 can occur.
  • the spring pressure of fingers 72 against board 20 will, to some extent, overcome the spring pressure of helical springs 90, thereby raising bus bar 68 a sufficient distance so as to ride clear of flanges 76.
  • the instant invention therefore is seen to eliminate the use of wire conductor hookup directly to terminals located on the electrical housing, it being envisioned that connections to the printed circuit board or the like will be made by flat cable connectors or the like. Thus it is seen, that on any printed circuit board it is possible to arrange a number of combinations of electrical actuators to thereby have any number of switches to make up gang switching assemblies.
  • An electrical actuator adapted to connect electrical circuits, said actuator comprising a generally rectangular housing of electrically nonconductive material, said housing having one wall formed with an opening therein, said opening being of generally rectangular configuration and having pivotally located therein a mechanical actuator including an elongated portion extending inwardly of said wall, said actuator having a pair of parallel flat faces thereon in respective engagement with a first two opposed surfaces of said opening, and a first and second pair of shoulder portions, said first pair of shoulder portions being cylindrical and in respective engagement with cylindrically relieved inner end portions of a second two opposed surfaces of said opening, said second pair of shoulder portions being in engagement with inner end flange portions of said first two opposed surfaces, said elongated portion being in engagement with a carriage member, said carriage member being elongated and adapted for reciprocal movement, and in engagement with an electrically conductive bus bar having a plurality of electrical contact portions carried thereon, and flanges extending interiorly from two opposite walls of said rectangular housing, said flanges engaging opposite parallel edges of a first face of said bus
  • An electrical actuator a set forth in claim 2 wherein said bus bar has detent means located on a second face thereof parallel to said first face, said faces being on opposite sides of said bus bar and generally parallel with said wall, ball means engaging said second face of said bus bar, and spring means between and in engagement with said wall and ball means to urge said ball means against said second face and said bus bar against said flanges, whereby, upon appropriate sliding movement of said bus bar, said ball means will engage said detent means to accurately locate said bus bar in a desired position.
  • contact portions comprise elongated fingers cantilevered to said bus bar and having curved end portions adapted to slidingly engage electrical circuit means located on the surface of a circuit board.
  • An electrical actuator as set forth in claim 4 wherein two opposite walls of said rectangular housing have slots located therein outwardly of said bus bar, said slots adapted to receive therein mating projecting edge portions of a circuit board whereby said elongated fingers will engage the facing surface of said circuit board upon connection therewith.
