Application led 'June 5,
My invention relates to switch construetion and more particularly to a tipping button switch construction of the type used i'or controlling automobile horns.
@ne ot the objects ot my invention is to provide an improved switch construction of this type which will be simple, durable, cheap and eiiicient.
Further objects will appear from the description and claims.
1n the drawings, in which two embodiments of my invention are shown- Figure 1 is an axial section;
Fig. 2 is a section on the line 2-2 of Fig. 1;
Fig. 3 isa bottoin'view of the switch base;
Fig. L1 is a section on th-e line 1 1 of Fig. 2;
Fig. 2; and
Fig. 5 is an axial section showing another form ot switch mounting.
Referring iirst to Figures 1 to 5, inclusive, the construction shown therein comprises an insulating base 10, a pair of wiring terminals 11 and 12 mounted on said base, .an annular switch contact` 13 `mounted on s'aid base, an insulating tipping button 111, a switch contact plate 15 mounted on said tipping button and cooperating with the annular contact 13, and means tor yieldingly supporting said tipping button on said insulating base and electrically connecting said binding terminals with said switch contacts, respectively.
The tipping button is .supported in its tipping movement by a hollow post or eyelet 16 and a. coil compression spring 17 mounted in said hollow post and pressing` upwardly on the tipping button, tending to hold the contact plate 15 in engagement with the outwardly extending annular flange on the hollow post. The hollow post is riveted to a metal stamping 18, which .stamping is secured on the insulating' base by means of the screw 19. The lower end of the post is reduced as indicated at 2O where it extends through the stamping and this reduction torms a shoulder on which the lower end of the spring 17 is seated. The contact plate 15 is held in place on the tipping button by a pair of eyelet members 21 imbedded in the insulating button and riveted over the contact plate.
For holding the annular contact member 5 is a section on the line 5 5 of Fig.
1924. Serial No. 713,631.
13 on the insulating base 1() and insulating and positioning the metal stamping 18 and the post 16, an insulating washer 22 ot iiber or oth-cr .suitable material is provided which is clamped underneath the metal stamping engages .a loop or strap portion 25 entend ing downwardly and inwardly from the ,an--
nular contact member, the `toot portion 2'? of which strap lies underneath the head of the screw. This screw 25 is threaded into the binding plate 28 ot the wiring terminal 12. For electrically connectingl the binding plate 29 of the wiring terminal 11 with the stamping 18 and for securing the binding plate and stamping on the insulating base 10 the screw` 19 is provided'which ext-ends through the binding plate 29, insulating base 10, and liber washer 22 and is threaded into the stamping, as shown in Figs. 3 and 1.
For holding the insulating bas-e 10 in place on the support 3() (which may be the spark lever ot the automobile) a pair o't screws 31 are provided which extend through the support and insulating base 1() and are providedwith nuts 32 at their upper ends.
The circuit is from the binding plate 29 through the screw 19, stamping 18, hollow post 16, contact plate 15, annular contact 13, loop 26, and screw 25 to the binding plate 28.
The insulating washer 22 serves to position and center the inet-al stamping 18 and tubular post 16, an aperture being provided in the insulated washer for this purpose, which receives thel lower end of the hollow post or eyelet asrindicated at 83 in Fig-s. l, 11 and 5.
The construction sho-wn in Fig. 6 is substantially the saine as that just described, except that here the insulating base 34 is seated in a cuplilre housing portion 35 formed with. the spart; lever and kul said post.
is held in place in this cup-like housing by means of a screw 36 extending through the side of the housing and threaded into a metal stamping 37 which is clamped underneath the insulating washer 22 and thereby held on the insulating base 34.
In operation, to sound the horn, the button 14 may be pressed at any point, causing some part of the contact plate 15 to engage the annular Contact 13 to close the circuit. Y
lhile I have shown but two forms of my invention7 it is obvious that it may be embodied in other forms covered and defined by the append-ed claims. n
Iilaving thus described my invention, what I elaiin as new anddesire to secure by Letters Patent oi? the United States is :f-
1. A tipping button switch construction comprising afbase, a hollow central post on said base, an insulating Ybutton tiltably mounted on said post, a Contact carried by said button, and a eoil compression spring mounted in said hollow post tor holding said button in operative tilting relation with respect to said post. I
21A tipping" button switohieonstruetion comprisinga base, a conductor plate mounted on said base, a central tubular metal post extending through and riveted to said plate,
an insulatingbutton tiltably mounted on said post7 a Contact carried by said button, a coil compression spring mounted in said hollow post for holding said button in operative tilting relation with respect to said post, said contact being eleetricallyconnected with said conductor plate through 3. A tipping button switch Construction comprising a base, a conductor plate mount-- led on said base, a central tubular metal post extending through and riveted to said plate, an insulating button tiltably mounted fou said post, a coil compression spring mounted in said hollow post tor holding said button in operative tilting relation with respect to said post, said Contact being` electrically connected with said conductor plate through said post. said tubular post having an internal annular shoulder atlording a seat tor the end oi' said coil spring'.
4. A tipping button switch construction comprising an insulating base, an annular Contact inen'iber thereon, a Conductor plate, a metal post mounted on said plate, a tiltable button mounted on said post, a conductor carried by said button cooperating' with said annular Contact and electrically counected with said plate through said post, and means forsecuring said annular contact on said base and positioning said plate comprising an insulating washer held in place on said base by said plate, said annularl Contact member having a member extending underneath said insulating washer.
5. A tippingbutton switch construction comprising au insulating base, an annular Contact mounted on said base, a conductor plate mounted on said base, a post mounted on said plate, a tiltable button mounted on ysaid post, a contact carried by said button cooperating` with said annular Contact, and means for holding said annular Contact ou said base and centering said` post compris` ing an insulating washer held in place by said plate.
In witness whereof, I have hereunto subscribed my name.
