ZOO/16X Primary Examiner-Robert K. Schaefer Assistant Examiner-.1. R. Scott Attorney-Edward C. Threedy ABSTRACT: An electric switch having an open-sided housing normally closed by a dielectric base supporting on opposite faces thereof transversely extending independent conductive elements with contacts for each of said elements exposed on one face of the base, and a slider carrying a contactor provided with a pair of interconnected spring contacts that wipably engage the exposed contacts of all of the conductive elements, with the slider positioned over the base by actuation of an operating lever carried by the slider that extends out wardly of the housing through an elongated slot formed therein.
CROSS BAR SLIDE SELECTOR SWITCH SUMMARY OF THE INVENTION A crossbar slide switch having a contactmember carried by and niovably positioned within a hollow housing, which comprises a one-piece open-sided casing normally closed by a printed circuit plate. Means provided by the contact member for simultaneously engaging a plurality of independent conductive elements provided by the printed circuit plate, and means provided by the casing for indexing the contact member in relation to the plurality of independent conductive elements as the contact member is selectively moved within the housing over the printed circuit plate.
GENERAL DESCRIPTION Reference is made to the accompanying drawing in which there is shown an illustrative embodiment of the invention and from which its novel features and advantages will be readily apparent.
The invention will be best understood by reference to the drawing in which:
FIG. 1 is a top plan view of the slide switch;
FIG. 2 is a side elevational view of the slide switch;
FIG. 3 is a detailed sectional view of the open-sided casing for the slide switch;
FIG. 4 is a fragmentary detailed sectional view 4-4 of FIG. I;
FIG. 5 is a fragmentary end elevational view of the slider as associated with this invention;
taken on line FIG. 6 is a perspective view of the spring contact member;-
and
FIG. 7 is a plan view of one side of the base or printed circuit board associated with this invention.
The accompanying drawings illustrate a crossbar slide switch 10 that comprises a one-piece molded casing defined by a top wall 11, sidewalls 12 and end walls 13. At each corner of the casing, adjacent the junction between the side and end walls, laterally extends a hollow stud 14, the purpose of which will be hereinafter explained.
The top wall I l of the casing has formed therein a plurality of elongated parallelly extending slots 15. As seen in FIG. 5 the longitudinal walls 16 which define the side edges of each of the slots have on their under surface a depending rib 17 which cooperate with each other to form elongated channels 18 beneath the slots 15. The under surface of the walls 16 to either side of their depending rib 17 are designed to provide a series of indexing teeth 19.
A dielectric base plate 20 is provided as a closure or bottom wall for the casing, and has on one face thereof printed con-.
ductive elements 22, and on its other face additional printed conductive elements 23, which include terminals 24 that project through the base 20 and are positioned in an exposed, isolated relationship to the printed conductive elements 22 on face 21, as seen in FIG. 7.
Referring to FIG. 4 there is shown a slider 25 which comprises an elongated rectangularly shaped body 26, the bottom surface of which is recessed as at 27 so as to contain a contactor 28.
The upper longitudinal side edges of the body 26 are cut away so that when the slider 25 is positioned in any one of the channels 18 the sides thereof will be between a pair of depending; ribs I7 and the indexing teeth 19 adjacent to each rib will extend through the area of the cutaway edges as shown in FIG. 5. In the area of the cutaway edgesthe slider 25 provides a pair of cams 29 at each side of the base of a laterally extending actuating level 30 integrally formed on the slider 25, and which is adapted to be projected out of a slot 15 formed in the top wall 11 of the switch casing as shown.
The contactor 28 is preferably formed from a single strand of spring wire, and as such has its medial portion 31 disposed within and extending diagonally across the bottom of, the p recess 27 formed in the body 26 of the slider 25. The opposite ends 32 of the medial dportion 31 are angularly bent thereto and terminate into ownwardly inclined legs 33 which yieldably support substantially flat contact portions 34 adjacent the opposite slightly elevated ends 35 of the spring wire piece as seen in FIG. 6.
When a slider 25, together with its contactor 28 is placed so that its actuating lever 30 is projected out of a slot 15, and the base plate 20 is positioned upon the hollow lugs 14 and the same are stacked through corresponding openings 36 formed in the base 20, the slide switch is completely assembled. The base 20 is provided with longitudinally extending terminal ends 37 and 38, each of which may be readily associated with suitable electrical connections.
As seen in FIGS. 4 and 5 the contact portions 34 of the contactor 28 will engage both the printed conductive element 22 and selectively the exposed terminal 24 of any one of the printed conductive elements 23. The earns 29 permit the movement of the slider 25 through the slot 15, and cooperates with the index teeth 19 to position the contactor 28 in selective engagement with the conductive elements 22 and exposed terminals 24 as desired.
While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.
