  • each of the apertures 140 in housing 12 is formed in the sidewalls of each of the apertures 140 in housing 12; thus preventing inadvertent removal of the pins from the switch housing.
  • the terminal may be removed, however, merely by bending the barbs to a position whereby the pin terminal may be withdrawn through a respective aperture.
  • a pair of wipers 106, 108 is provided in each wiper assembly to be operated by slide control lever 39a.
  • the wipers are separated by central portion 148 of the lower end 100 of operating member 37a, to form two independent wiper contacts for use with separate circuit configurations, if desired.

  • force applied to the rocker assembly is transferred therefrom to the control by depressing one .or the other end of the actuating member of the former.
  • a continuation of the application of force to the rocker actuating member 52 causes the end surface of projection 64 to engage the inclined surface 90 (FIG. 4) about aperture 36a in plate 35a and to cam thereover until surface 74 of the projection 64 ultimately reaches a position like that of projection 66 (FIG. 3); i.e., inserted partially into aperture 36a and wedged between surface 86 of the lever 39a. and inclined surface 90.
  • rib 134 of the wiper assembly moves from the first recess along surface 152 to the second recess therein, thereby to detent the wiper assembly 40a in a position wherein wiper contacts 136 engage pins 142, numbered 2 and 3 (FIG. 9) to provide an electrical connection therebetween.
  • each of the wiper contacts 136 remains in wiping, contacting engagement with a corresponding center pin terminal 2 (FIG. 9), but breaks and makes contactwith pins 1 and 3, depending upon the direction of movement of the Wiper assembly 40a. Because the wipers are of a spring metal they are able to be twisted or pivoted within the housing so as to always make a wiping contact with mating pin terminals, and to insure a good electrical connection therebetween.
  • pin terminals 142 also also correspondingly numbered from 1 to 3 and wiper contacts 136 are shown in two positions; i.e., electrically connecting pins 1 and 2, and in the process of being moved to make contact with pins 1 and 3.
  • wiper contacts 136 when wiper contacts 136 are moved from the position at the left, towards pin 3, they twist or rotate so as to engage pin 3 at the rounded ends 138 of the wiper contacts. This causes a wiping of the contacts 136 against respective pins 3, as well as against pins 2, to clean any deposit or corrosion therefrom and in turn to insure a good electrical connection therebetween. Ultimately, the wiper contacts assume a position as shown at the left in FIG. 11, with the wiper contacts 136 being in direct engagement with both of the pins.
  • each of the wiper contacts 136 is provided by rib 128 formed on leg 122 of the wipers 106, 108, respectively (FIGS. 6 and 7). As shown in FIG. 9, ribs 128 of the pair of wipers rest against respective inner wall surfaces 156 of operating member 37a of the wiper assembly, and are capable of pivoting on ribs 128 thereon. In this manner, the wiper contacts 136 rock or twist to engage the respective pin terminals 142, with a thorough wiping action as the wiper assembly is moved back and forth to operate the switch.
  • pin terminals 142 are placed into re Spective apertures 140 in switch housing 12 and inadvertently assume positions which cause them to be out of alignment with each other. This will not affect the operation of the switch, however, since wiper contacts 136 are able to accommodate for such misalignment.
  • An example of such positioning of the pin terminals is illustrated diagrammatically in FIG. 12 wherein the center pin terminals designated 2 are out of alignment with terminals 1 and 3.
  • the upper pin terminal 2 as seen in the figure, is positioned toward the mating wiper contact 136' and the lower pin terminal 2 is positioned away from the other mating wiper contact 136.
  • the pivoting action of wipers 106, 108 about respective ribs 128 causes the wiper contacts to make adequate contact with the pin members.
  • wiper contact 136 pivots clockwise to interconnect pins 1 and 2 and counterclockwise to interconnect pins 1 and 3.
  • the lower wiper 106 likewise, pivots in either a clock- Wise or counterclockwise direction, as the case may be, to interconnect respective pin terminals.
  • pin terminals 142 as heretofore shown and described are in many instances entirely satisfactory. However, they are more or less cantilevered in position and have little resilience in mounted position. Accordingly, I have invented an improved form of my slide switch. This switch is illustrated in FIGS. l3-l7.
  • the rocker operator although not shown in these figures, is equally applicable. The parts are either the same as those previously described or are functionally equivalent thereto.
  • the upper housing section 22b includes a pair of flexible cantilevered flanges 160 received in channels 162 on the lower housing section and carrying the arms 26b.

However, the lower end thereof is somewhat larger and is provided with downwardly and laterally opening L-shaped slots 168 receiving generally complementary shaped flanges 170 of the movable wiper or shorting contacts 10Gb and 108b. Each of these wipers more or less floats on the operating member, the slots 168 being of larger dimension than the flanges 170 and includes a contacting face 172 with spaced, vertical flutes 174 therein to detent the fixed contacts or terminal members.
