ELECTRIC SWITCH Original Filed July 25, 1927 ferred form of embodiment of Patented Mar. 31, '1931 "UNITED STATES PATENT OFFICE HARRY E. NORVIEL, OF ANDERSON, INDIANA, ASSIGNOR TO DELCO-REMY CORPORA- TION, OI DAYTON, OHIO, A CORPORATION OF DELAWARE ELECTRIC SWITCH Application filed July 25, 1927, Serial No. 208,084. Renewed January 13, .1930.
This invention relates to electrical switches for controlling the electrical circuits of an automobile and one of its objects is to simplify the construction of and reduce the cost of manufacture of switches of this type.
Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a pre- Y the present invention is clearly shown.
Inthe drawings:
Fig. 1 is a front view of a ing the present invention.
Fig. 2 is a sectional view on the line 22 of Fig. 1..
Fig. 3 is a fragmentary back view looking in the direction of arrow 3 in Fig. 2.
Figs. 4 and 5 are sectional views taken switch embodyrespectively on the lines 4-4 and 55 of Fig. 2.
Figs. 6 and 7 are fragmentary sectional Views taken respectively on the lines 6-6 and 77 of Fig. 4.
In the drawings, 20 designates the main supporting plate or mounting bracket of the switch. The bracket 20 is provided with hooked ears 21 which engage anglebars 22 extending along the back of an instrument board 23 and secured thereto in any suitable manner. The bracket 20 is provided with a tubular switch case portion 24 to which is attached a non-conducting switch back 25 carrying tubular rivets 26 which provide switch terminals and which are counterbored at 27 to provide conical surfaces providing the stationary switch contacts. The periphery of the back 25' is notched to receive tangs 28 extending from the tubular portion 24. The tangs are bent" at 29 against the back 25 to secure the same to the part 24.
The bracket 20 supports a dial plate 30 attached thereto by bezel ring 31 having a fiat flange 32 in engagement with the bracket 20 and securedv thereto by tangs 33 which are bent into notches 34 provided in the bracket 20 and bent against the back side of the bracket. When assembled with the bracket,
50 the dial plate 30 is'provided with an aperture 35, the wall of which provides a bearing 39 and 40 which bear against for the hub 36 of a lever 37.
Lever 37 is provided within the switch case a non-conducting plate 43 which is rotatable 7 about a pin 44 attached to the back 25. As the pin 44 is coaxial with the bearing 35, it is apparent that this pin and bearing cooperate to rotatably support the handle 37 and plate 43. The tangs 41 of the handle 37 pass also intorectangular holes 45 in a non-conducting plate 46 so that the plate 46 will be driven by the handle. The plate 46 is drivingly connected with a contact disc 47 and with a non-conducting plate 48 by rivets 49 along which theplate 47 and the plate 48 are freely slidable. The heads of the rivets 49 limit the separation of the'plates 47 and 48 from the plate 46 due to the springs 50. One end of each spring bears against a cup-shaped spring seat member [51 which is received by aligned holes in the plates 43 and are each received within a semi-spherical recess provided by a semi-spherical embossed portion 53 providingone of the contacts of thecontact plate 47. The contacts 53 are urged by the springs 50 into engagement with the inner surface of the switch back 25 or into engagement with certain of the stationary contacts 27 for the purpose of controlling the lighting circuit of an automobile. If desired, the rivets 49 may be freely slidable through the plate 46 and the heads thereof are received by holes 54 in the plate 43. The disc 48 is journalled upon the pin 44. This construction aids in maintaining concentricity between the plates 43, 46 and the contact plate 47. p I
The disc 48. supports a contact plate which is drivingly connected with the plate 48 by providing it with notches 61 which plate 60 is provided with notches 63 for clearing the heads of therivets 49 so that the plate 60 will be insulated from the plate 47. Plate 60 is provided with buttons 64 and 65 providing switch contacts which are engageable with arcuate contact plates 66 and 67 respectively for the purpose of connecting 5 an ignition coil terminal 68 with a battery terminal 69 with which the contact 67 is always connected.
The springs 50 urge the contacts 64 and 65 into engagement with the contacts 66 and 67 as well as urging the lighting switch contact 53 into engagement with the lighting circuit stationary contact 27. The handle 37 is movable into five different positions namely: park, ofi, ignition, dim, on and is resilient- 1'5 ly maintained in either of these positions due to the cooperation of the spherical contacts 53' with the conically recessed stationary contacts 27 with which each contact 53 is maintained in engagement by a spring 50.
The handle 37 is limited in its movement by the engagement of a lug 70 extending from the plate 43 with either of two stop lugs 71 which are formed by partly punching out and bending portions of a wall 72 of the v bracket 20. The wall 72 cooperates with an arcuate wall 73 to enclose an arcuate recess 74 through which the lug 70 moves and into which the lug 71 extends.
The parts of the switch are assembled by making the sub-assembly of the bracket.20,
the dial plate 30, and the bezel ring 31. The gin 44 is assembled with the switch back 25. efore the back 25 it attached to the bracket 20, the handle 37 is passed through the dial plate 30 from the inner surface thereof, the
hole surrounded by the bearing 35 being large enough to permit movement of the handle through it. Then the plates 43, 46 and parts attached to the plate 46 as shown 40 in Fig. 6 are assembled within the case 24 and are attached to the handle 37 by causing the tangs 41 to extend through the rectangular holes 42 in the plates 43 and 46. Then the switch back 25 is secured tothe case 24. The
45 springs not only maintain the movable contacts'in engagement with the stationary contacts but also urge the plate 46 toward the plate 43, the plate .43 against the flanges 38, 39 and 40 of the handle and urge these 50- flanges against the inside surface of the dial plate 30. Therefore all end play between these parts is taken up by the spring so that the switch will not be noisy when subjected to vibration.
While the form of embodiment of the present invention-asherein disclosed, constitutestion pressed therein substantially perpen dicular to said dial plate to form a switch insulated rotary contact plates drivingly connected to but insulated from said'hub portion, each of said contact plates having'contactpoints arranged to engage certain of said stationary contacts on said switch back.
