My invention relates to switch construction and more specifically to a two-circuit switch construction suitable for controlling the horn and lights of an automobile.
One of the objects of my invention is to provide. a switch construction of this type which will be simple, cheap, durable and efiicient.
Further objects will appear from the description and claims.
In the drawings, in which an embodiment of my invention is shown Figure 1 is an axial section of the switch construction; r
Fig. 2 is a section on the line 22 of Fig. 1;
Fig. 3 is a section on the line 33 oi Fig. 1;
Fig. 4 is a section on the line H of Fig. 3.
Fig. 5 is a section on the line 55 of Fig. 2;
'Fig. 6 is a bottom view of the switch; and
Fig. 7 is a section showing the switch changed over from a grounded lighting circuit to a metallic lighting circuit.
Referring now to the drawings in detail, the construction shown therein comprises an insulating base '10, wiring terminals 19 and 12 mounted thereon for the horn and light circuits respectively, a grounded annular contact 13 also mounted on said insulating base affording a ground for both the horn and light circuits, a tiltable insulating button 14 for controlling the horn circuit and an insu- 15 for controlling the light circuit. The inshaped housing member 16 which may formed integrally with the spark lever, this metal member forming a ground for both circuits through the metalstamping 17 (Fig.-
4) which electrically and mechanically connects the annular contact member 13 with the metal housing 16. The tiltable horn button 14 carries a metal contact plate 18 which cooperates with the annular grounded ,co n
tact 13.
The circuit from the binding terminal 11 to the contact plate 18 is through the tubular metal member 19, into which the binding.
screw 20 is threaded, the metal plate 21 riveted to the tubular member 19 and the tubular metal post 22 riveted to the metal plate 21 For yieldingly supporting the tiltablebutton in operative relation with respect to the post-22, a coil compression spring 23 is pro' Vided which acts between the metal plate 21 and the contact plate 18 to hold the -latter y1eld1ngly in engagement with the annular fulcrum flange 24 on the tubutar post 22.
The annular grounded contact 13 is formed as an outwardly extending flange on the cupshapedmetal member 25 which is mounted on the lnsulating base 10. This cup-shaped metal member, as well as the metal plate 21 and tubular post are held in place on the insulating base by means ofan axial screw 26 extending through the insulating base and threaded into the tubular post. An insulatmg washer 27 is interposed between the metal plate21 and the bottom of the metal cup-like member to clampingly engage the bottom of the cup and to insulate it from the metal plate. The cylindrical portion of the metal cup member has a working fit in the opening in the annular light-controlling operating member 15 so that this operating member is-oscillatably mounted, partly on the insulating base 10 and partlyon the cylindrical portion of the metal cup member, and is held in place againstend-wise movement by the outwardly extending contact flange 13. A
The lighting circuit from the wiring terminal 12 to the grounded metal cup 25 comprises the tubular member 28 into which the end of the supply wire isinserted, a contact member 29 formed integrally with the tubularmember 28, a double leaf-spring member 30 mounted on the oscillatable annular mem- Y tact members 29 and 31, respectively, when the switch is turned to on position, as shown in Fig. 2. Positioning notches 34 a'nd 35 are provided on the insulating base 10 to receive the inwardly bent portions 36 and 37 of the leaf-spring contact members when the switch is in closed as position.
As indicated above, the metal cup member 7 25'is mechanically and electrically connected the bottom of the cup member at 38 and secured to the metal housing by means of a the strip is sprung by the screw 39 when the"- stamping is drawn up snugly against the inside of the cup-like housing. This tensionin the metal stamping 17 holds the switch mechanism snugly against the other side of the housing member 16 and prevents any looseness of parts,
The metal piece comprising the contact 29 and tubular part 28 is inserted into the opening in the insulating base from the upper side and is held in place on the insulating base by means of the binding screw 40 which is threaded into the side of the tubular binding terminal portion. This contact and binding terminal member is held against downward movement in the insulating base by means of the square upper contact portion 29 and is held. against upward movement in the insulating base by engagement of the laterally extending screw 40 with the lower'face of the insulating base. 1 I
When the oscillatable operating member is operated, the lighting circuit is broken at two points by the double leaf-spring switching member 30 in cooperation with the contact members 29 and 31.
In case it is desired to change over the construction so that the lighting circuit will beametallic circuit as distinguished from a grounded circuit, the construction shown 1n .Fig. 7 is used. A metal cup member 25 is substituted for the metal cup 25 of the construction just described, this cup member having no downwardly extending contact lug corresponding to the downwardly extending contact lug31, shown in Fig- 5. In place of this grounded contact lug, acontact 41 is provided which is securedby a screw 42 to the tubular wiring terminal member 43 mounted on the insulating base 10. This wiring terminal member 43 has an axial recess 44 there-.
in to receive the end of the supply wire and is provided with a binding screw 45 which is threaded into the side of the tubular portion and engages the end of the supply wire to hold it in place. The contact 41 cooperates with the leaf-spring contact member 33 just as does the contact lug 31 in the co nstruction previously described. i
In operation, to sound the horn, the button "14 may be pressed at any p0int, which will cause some part of the contact plate 18 to en-\ gage the annular contact 13 to close the cir-.
cu1t. i To close the lighting circuit, the annular 'controlling member 15 is moved to a position .tocause the spring contact'members 32and 33 to engage the'contacts 2-9 and 31.
