iliis invention pertains to electric switches esi 'ned for the control of a plurality ct cirand s particularly concerned with Lllllii ype of sw tch mounted upon the lower end of ring post of an automotive vehicle and ed for controlling a number of circuits by a controller carried y the post.

It is an 0? ject of in tent invention to provide a switch of the class describes that is simple in construction and compact in form.

It is a further object of the instant invention to provide a switch structure that is capable of selectively controlling circuits by both an axial and angular movement of parts of the switch structure.

It is a further object of the in ention to provide switch structure having a plurality of movable contacts, and in which axial movement part of the switch structure will co- Lrol certain circnts irrespective of the ang ar position. of said switch structure in controlling other circuits therethrough.

' I i a. further object of the instant invention to pro ide means for maintaining the contacts in engagement with a terminal support at the same time restraining one of the contact members from engagement with said Lerminal support.

Fur ier objects and advantages oi the p inver ion will be apparent from the r -lowing lescription, reference being had to wherein a prethe accompanying drawing, ferred embodiment of one form of he present .ention clearly shown.

l 6 and 7 are details of the horn contact memben in the dra 2O refers to a position of ie steerirq L est r. nich may be secured to the a1 ie oi the vehicle by the attaching lug :21 and bolt and nut device 22, and may include oer control tubes .43 connected to cont-ol members it at the hub of the steer in heel 25. @ne of these control member as :ao *rminates at the hub oi the wheel with a button 27 and extends beyond the lower end of the post through the attaching flange 28 where LL has driving engagement with the switch structure as will presently appear. In

slant invention the switch structure is osed in a housing 30 of cup form, the o-c-uom b i I secured to a U-shaped bracket 32 havin attaching ears 33, secured e the post 20, by the bolt and The bottom 31 of the cup centrally apertured and g at 35 to provide a sleeve the aperture of the bracket 31, a bearing for the head 36 of a shalt that is drivingly connected rol member 26 by means of a -n the housing there is a dielectric (r g plate -10 having a hub ll, provided with a bore concentric therewith for receiving the shaft 3'7 that has a driving engagement therewith by means of the nonrounded head 36. Thus, driving engagement is provided between the dielectric member l0 and the push-pull controller 26. The member 40, as will be seen by reference to Figs. 1 and 5., is further provided with appoint ments including the raised central area or plateau l l supporting the hub a l, which plateau radially grooved at 45, 46, 47 and 48 providing driving engagement and one way mating relation with cooperating extensions d9, 50, 51 and 52 of a contact plate 53. A. por .ion 01" the edge of the plate is removed to provide the arcuate notch 54 that cooperates with a squirtor tongue 55 in. the

p plate 40.

is of relatively open foraminous construc' tion as illustrated. The plate is centrally apertured at 56 of sufficient dimension to be disposed over the hub 41 of the drive plate 40, an'dadjacent this aperture are located the extensions or squirts 49,50, 51 and 52 which provide the driving engagement with the At each apex of the triangular plate, the same is deformed into the contact points 51 58' and 59, and portions of the plate betweenithese contact points and the central aperture 56 are punched out as at 60, 61 and 62 so that each of. the contact points 57,58 and 59 will be joined to the main body of the plate by a'pair of integrally formed dii erging, resilient or flexible arms 63 and 64. Each pair of diverging arms 63 and 64 are bent outof the plane of the main portion of the plate as indicated at 65 in Fig. 4 for a purpose which will presently appear, as illustrated in ig. 1. v

The hub 41 of the dielectric member also supports asecond contact'member as illustrated in detail in Figs. 6 and 7. This contact member comprises a washer like ring 7101 resilient metal providing a central aperture 2 fordisposition over the hub 41, and one or more lateral extensions 73, laterally flexed at 74 as illustrated in the detailed showing provide contact engaging portions.

, In assembling these elements with the driving member, a contact urging spring is placed uponthe driving member 40 so as to be disposed about the raised portion 44, and the contact member 53 is then passed over the hub with the extensions 49., 50, 51 and 52 disposed for engagement within the radial slots 45, 46, 4'7 and 48 respectively. This will bring the contact points 57, 58 and 59 in direct engagement with portions of the spring 80, for a purpose presently to appear.

The contact member 70 is then placed over tbehub and second spring 81 is disposed thereagainst to engage the ring portion 71 andforce the same into engagement with the contact member This spring 7 also tends to ma nta n the plate 53 in driving engagement with the plate40. "A switch back 85.is.theiiplaced upon the 30 to close olithe same, and is retained in such position by the tongues 86 peripherally arranged about the casing so md bent against the back. s de thereof as illustrated in Figs. 1 and 2.

' This switch back provides a plurality. of fixed contacts 87 arranged in concentric form about an aperture 88. of the switch back, and adapted for cooperation withone or another of the various contact points 57, 58 and 59 of thecontact plate 53. The fixed contacts 87 may terminate exterior of the switch back in teininal clips 89 asillustrated in Fig. 1. Concentric with the aperture88 the switch back also provides a contact ring 90 that is 1 arranged for engagement by the extensions 73 of the contact plate TO'and may terminate on the rear side of the switch back in a terminal clip 91. Concentric with the aperture 88and within the ring 90,'the switch baci: is provided with a countersinlr-92 within which maybe seated the spring 81. i i

it will be understood of course. that when the switch back is secured to the housing 30', that the switch structure will be confined between it and the bottom 31 of the said housing. The springs 80 and 81 will then be underv compression so that the contact plates 53 and 70 will be maintained in disposition upon the hub 41 with the driving positions of the plate 40 in mating engagement with the reciprocal positions oftlie plate 53, and so that the spring 80 will urge the contact points of the plate 53 individually into engagement with the switch back 85. These facts will obtain throughout the normal disposition of forces within tne switch structure. The constructicn of the contact plate 53 is such as to provide the contact points 57, 58 and 59 as being independently nexible relative to the body of the plate so that when mounted upon the dielectric member 40 and subjected to the urging of the spring forces described, that the contact support assembly will readily, assume the position illustrated in F 1g. 1. The

contact points of the plate 53 will each normally be in engagement with the switch back 85,:and the contact member 70 Wlll be out of engagement with any portion of the switch ac V v I However, the structure is such that the driving member 40 may be moved to any angular position permitted by the stop-provisions 54 V and 55 and at the same time will be permissible of axial movement independent of any of said angular positions. 7 That is, the

contact assembly'maybe moved to any of the angular positions, and irrespective of that angular position may be moved axially without affecting the angular position of said movement.

In main the spring .81 is a return spring for the contact member 7 0 so as to move it away from the contact ring when pressure upon the control member 27 is released, but

it may, however, contribute to the movement of the entire contact actuating assembly upon such release. The spring 80 performs a dual function, in that, it not only maintainsthe contact points 57, 58 and 59, in engagement with the switch back, but also functions to re,- turnthe contact assembly to the position of rest as exhibited in F 1'. directly that pressure is released upon the control member27. This aids in Withdrawing the contact member 70 from the contact ring 90. This spring force tends to urge the. driving member 40 and the contact points of the plate 53 against opposing walls of the switch housing.
