Filed Dec. 9, 1929 Patented Apr. 14, 1931 UNITED STATES PATENT OFFICE I HARRY NORVIEL, F ANDERSON, INDIANA, ASSIGNOR T0 DELCO-REIIIY CORPORA- TION, 0F ANDERSON, INDIANA, A CORPORATION OF DELAWARE SWITCH Application filed December 9, 1929. Serial No. 412,739.

This invention relates to switches designed to control a plurality of circuits. 7

One of the objects of the instant invention is to provide a-s-witch structure of the rotary or ,oscillatable type adapted to be operated by a push-pull movement of the controller. 2 A further object of this invention is to provide a push-pull actuator adapted to move a contact actuator assembly into a plurality of positions.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to'the accompanying drawings wherein a preferred embodiment of one form of the present invention is clearly shown.

In the drawings:

Fig. '1' is a. rear elevation of a switch device involving the instant invention, and is substantially that view illustrated by the arrow 1 of Fig. 2.

Fig. 2 is a longitudinal section through the switch device substantially as indicated by theline and arrows 22 of Fig. 1.

2, Fig. 3 is a sectional view through the switch device substantially as indicated by the line and arrows 3-3 of Fig. 2, the 0011 tact plate being shown in the off position.

Fig; 4 is a similar view along the same line,

b 0 but showing the contact plate moved into one of the circuit completing positions. Fig. 5 isa view similar to Fig. 4, with the contact plate moved to a second circuit complating position.

Fig. 6 is-an elevational view of the switch structure substantially as indicated by the arrow 6 of Fig. 2. c '7 is a section through the switch device showing the actuator assembly in elevation substantially as indicated by the line and arrows 7-7 of Fig. 2'.

Fig. 8 is a detail of the driving cup contributing to the instant invention.

With particular reference to the drawing, 20 indicates an attaching bracket which may be formed, of sheet metal to provide a shelf,

portion 21 and apertured attaching ears 22 whi'chprovide means for attaching the structure to a dash orinstrument panel 23 as by 59 the bolt and nut device 24. To the shelf portion 21 of the bracket is secured a cup shaped housing 25 that has a back wall 26 in con junctive relation with the shelf 21 and apertured at 27 for the reception and actuation of a driving cup presently to be described. A switch back 28 providing a plurality of terminal lugs 29 exterior of the back 28, and fixed contact points 30 within the case, operates to close the housing 25 and may be secured thereon by tangs 31 circumferentially spaced about the housing and received in grooves or notches 32 of the switch back. The switch back when assembled with the housing 25 forms a substantially parallel wall with the bottom 26, and is apertured at 33 coaxial with the aperture 27 for reception and guidance of the driving cup heretofore referred to.

Within the housing provided by the cup 25 and the switch back 28, there is a contact actuating assembly mounted for rotatable or oscillatable engagement with the fixed contacts 30 of the switch back, and that has driving engagement with the cup heretofore mentioned. This assembly comprises the contact plate 35 here illustrated as of tri angular form, at the several apeXes of which are formed the semi-spherical contact points or buttons 36 adjacent attaching tangs 37 that have seating and clinching engagement with notches 38 circumferential'ly disposed about the periphery of a dielectric supporting plate 39, as illustrated in Figs.r2 and 7. Both the contact plate and the dielectric member are centrally apertured as at 40V and 41 respectively for passage of the heretofore mentioned driving cup.

At points intermediate the notches 38 of the plate 39, the same is provided with additional notches 42 which loosely receive the driving tongues 43 of a driving plate 44, that is also apertured at 45 for disposition about the said driving cup. In addition to the tongues 43 the plate 44 is provided with extensions or lugs 46 that are concentric with the central aperture 45 and operate to centrailly dispose a spring 47 interposed between the said plate 44 and the dielectric member 39 prior to assembling the same. The contact supporting member 39 and the driving will be maintained in engagement with the surface of the switch back 28, while the driving plate 44 will be maintained in engagement with the bottom 26 of the housing 25.

This provides for slight axial movementof the contact supporting assembly relative to the switch back and case bottom as the contact plate moves over. any inequalities of surface on the switch back.

, In addition to the above appointments the driving plate 44 is provided with a tongue '50 projecting into the central aperture 45,

and the bottom of the case 26 is provided with a similar tongue 51 projecting inwardly from the edge of the aperture 27. These tongue members provide for mating and driving en gagement between the housing and the driving plate through the cooperation of a driving cup 60,. the details of which are IllIlS'. trated in Fig. 8. The driving cup 60 is of substantial dimension to be freely movable through the aligned apertures of the switch back 28 and the casing bottom 26, and the side walls thereof are provided with slots 61 and 62 whichhave interfitting engagement with the tongues 50 and 51 respectively, just described. The driving cup is mounted in the structure so asto be freely movable in a lineal direction through the apertures 27 and 33 of the housing and back respectively, and so that the tongue 50 will be disposed within the slot 61 while the tongue '51 will be disposed in the slot 62.

To the head or bottom 63 of the cup, a coupling'member 64 is secured as by a rivet 65, and provides the attaching ears 66 to which a push-pull controller may be attached and led through the instrument panel 23 substantially as indicated in dashed lines of Fig. 2. The coupling member 64' provides the oppositely disposed ears 67 which operate vas stops against the shelf 21 of the attaching bracket. It will be noted from the illustration of Figs. 2 and 8,that the slots 61 r and 62 are of dilferent character, that is, the

groove 61 is one of spiral 'formation,while the slot 62 is straight. These slots in cooperation with the respective tongues 50 and 51 provide a difierential splined engagement between the cup bottom and the contact actuator assembly. One of the slots and'tongue provisions operates to restrain the driving cup 60 from rotation relative to the bracket and housing 25 in its movement therethrough, while the other slot and tongue engagement operates to cause a change in the angular position of the contact support assembly relative to the switch back upon movement of the driving cup through the parts 26 and 28 of the enclosure.

It is obvious from the drawings that movement of the controller, and thus the driving cup as illustrated in Fig. 2 will produce a rotation or oscillation of the contact plate 35 from the oif position as illustrated in Fig. 3 to the first circuit closing position illustrated in Fig. 4 and thence to the second circuit closing position illustrated in Fig. 5, whenever the controller is moved from the inward position illustrated in Fig. 2 to that of the fully withdrawn position. In Figs. 3, 4 and'5 the relative position of the tongues 50 and51 are shown in dotted'lines for the purpose of illustrating the relative-movement of the parts that takes place when the switch device is actuated. Of course during movement of the controller from the extended position to that of'fully depressed, or the reverse of the movement that has just been outlined, the contact plate 35 will be returned to the off position as illustrated in Fig. 3.
