This invention relates to electric switches in combination with an ignition coil, and one of the objects is to provide a novel and simple means of controlling the circuits through the ignition coil in conj unction'with certain registering or indicating circuits so that a key controlled device will simultaneously operate to open and close all of the circuits and to secure them in open relation.`

A further object of the invention is to provide a unit of structure which includes in addition to the key controlled means for securing the ignition circuit in open position, meansfor opening and closing the circuit of an electricalregister and coincidentally securing the same in open relation with the ignition circuit.

In the present invention these aims are accomplished by providing an electric switch in which a movable contact element is a leaf spring conductor fixed at an intermediate point to one of the ignition terminals of the coil and having the bowed free ends thereof adapted to engage a convex surface provided by suitable stationary contacts. A movable actuating member presses each end of the contact blade against the stationary contacts, one of which is a second ignition contact and the other a contact of said register circuit.

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

In the drawing:

Fig.,` 5 is a longitudinal sectional view through the contact actuator assembly, ,sube stantially as indicated by the line and arrows 5--5 of Fig.l l.

Fig. 6 is a diagrammatic view of the elecptrical circuit through my improved switch and coil unit. With particular references to the drawing, 2O indicates a case enclosing an ignition coil and is attached toa sleeve 21 secured to a mounting lbracket 22, which sleeve 2l has an interiitting relation with a metallic end wall or frame member 23 completing a switch housing and supporting a key controlled actuator for a switch mechanism later to be described. The case is lianged at 24 to receive a nonconducting member 25, forming a switch base and providing an end wall of the ignition coil housing. The non-conducting member 25 is provided witlr, a skirt 26 positioning a block 27 centrally recessed at 28 within which is received one end of a core 29. About the core are superimposed a secondary winding 30, and a primary winding 3l the other end of the core 29 being supported by a skirt 32 of the coil cap 33 which is secured to the case 20 lby an interlocking joint 34. Within the case 20 and about the coil windings there is provided a magnetic winding 35 which is grounded to the case 2O in the usual manner. i

The coil cap 33 is of molded formation and secures within the body thereof a high tension terminal which has connection by a pin 4l with the core 29 of the coil and thence to the inside turn'of the secondary winding. The cap also moldably secures a battery terminal post 42, a gas gage terminal 43 and a timer terminal 44, which have appropriate connections to and through the ignition coil to complementary terminal membersmoldably secured to the member 25. The nonconducting member 25 supports terminal members 50, 5l and 52 which form the elements of a switch mechanism as will presently appear. The member is connectedbya wire 53 with the gas gage terminal 43 while theterminal member 5l is connected by a lead 54 with the terminal post 42 and the terminal member 52 by a wire 55 to the insidelead of the primary and the outside of the secondary, and from thence by way of the primary 31 and outside lead 56 thereof to the post 44, and also from thence by way of the secondary windings to the core 29.

To the terminal member 51 there is secured an arc. shapedy spring leaf contact blade 60 which is crimped into a rather sinuous formation as shown in Fig. l, so that the concave free ends 61 and 62 lieV over the terminalmembers 50 andvv 52f-respectively, but are normally spaced therefrom or out of contact therewith.

The frame member 23 supports a key cylinder 65 carrying bolts 66 which cooperate with al key 67 to permit the key cylinder 65 to be rotated' Within the frame. A stop post 68 formed upon theframe member 23 adjacent the inner end of the key cylinder 65 acts as alstop.v and deiines'the limits of rotation of the cylinder. To the inner end of the key cylinder 65 is secured a contact actuator mechan ism by screws 69 driven 'through a nonconducting ratchet plate 70 and al supporting plate 7l. rlhe plates 70 and 71 are somewhat arcor crescent shaped as exhibited in Fig. 3, and.' provide arms 72 and 73, which in assembled relationv cooperate with the contact arms 6l and 62 to complete the circuits through themember 51 and the members 50 and 52;. The arms of the member 70 are of such dimension that junctures- 74 and 75 operateA as stops-in conjunction with the post 68 to. limit the rotary movement of the contact actuator. The intermediate portion of the members 7 Oand 71 are apertured at 76 and 77 to provide detent recesses to cooperate with the spring 78 and ratchet balll 7 9 secured withinthe frame member 23 temporarily retainingthe actuator device in the actuated positionv to which it may be moved.

When the frame andy contact actuator assembly are assembled with the sleeve 21, the tangs 80 of the said sleeve are bent into recesses 81 about the periphery of the the frame 23 and the switch actuating arms 72 and 73 are. disposed `in a relative position exhibited in Fig. 3, in. which the switchv parts are arranged in the ofi:z position. A face plate and a dial plate 91 are then placed over the frame. 23 and. securedv by screws 93 and iini'shed oif by bezel'ring 94.

lThe unit herein. above described is complete. in itself and is adapted for mounting 'uponz any substantial partv of the vehicle structure after which the high tension terminal'. 40 may be connected with the usual distributor 100, the terminal post 42 with the battery 101 and thence grounded at 102, the terminal 43 is then connected with the gasgageI 103V by a conductor 104 and thence grounded. at 105, and the terminal 44 is connected; tofthe timer 106, thence to the ground 107 as .illustrated in Fig. 6.

YVlieneverk the switch is manipulatedi to open or close the various circuits, the contact elements 61 and 62 are caused to rub over the respective terminal members 50 and 52 by reason of the arms 72 and 73. In forcing the elements 6l and 62 into engagement with the contacts 50 and 52, the arms 7 2 and 7 3 williron out the concave bends 61 and 62 and in doing so will cause the free ends of the member 60 to slide over the convex parts 50 and 52. It is to bel noted that the terminal 51 formsl a common terminal with the coil circuit through the terminal 52 and with the registering circuit through the terminal 50, and that-when the. plate 70 is rotated that these circuits are opened and closed coincidentally. Closing' ofthe coil circuit thereby establishes a closed registering circuit `by' which the indicia may be read oif. Since the registering circuit functions only when the coil circuity functions, danger of battery depletion is reduced to a minimum, for when thecoil circuit is opened the registering circuit is likewise opened thus being no drag upon the battery while the vehicle is at rest.

While the form of embodiment of the present invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scopeof the claims which follow.

What is claimed is as follows: 1. A switch comprising threeterminals arranged in a row, a spring metal' conductor attached intermediate its ends tothe center terminal, and having its free ends located so as lto engage respectively the other terminals, and means for causing the ends' of the spring conductor to simultaneously engage said other terminals, said means comprising a movable member having blades so constructed and arranged that, when the movable member is inthe off position, one of the blades will be positioned intermediate the ends of the spring conductor andthe other blade will be located beyond the end of said spring conductor.
