It is known that there exist hand switches intended to short-circuit the lighting dynanro automatic cut-out fitted in vehicles with explosion engines with the object of making the equipment operate without the aid of the battery. Nevertheless these hand switches do not insulate the battery and only short-circuit the automatic cutout, thus making it necessary to break the circuit of one of the cables of the battery terminals. 10 Another inconvenience is the fact t at with a battery charged, if the switch is left in he dynamo position, the battery discharges, when the dynamo is at rest, back through the dynamo.

The hand switch forming the object of the pres- 15 cut invention has also the aim of short-circuiting the automatic charging cut-out, but in a quite difierent way, by completely insulating the battery from the remainder of the installation. In addition this switch is made up in such a way that it at the same time enables the current in the inductors to be switched oil and the dynamo to operate on the poles constituted by permanent magnets.

The invention can in any case be well understood with the aid ofthe supplementary description below and of the attached drawing, which description and drawing are, of course, given above all by way of example.

Figure 1 represents the switch in the battery 30 position. I

Figure 2 is a straightened section of this switch in the battery position, through the line 2-2 of Figure 1.-

Figure 3 gives the view from below.

said switch. I

Figure 6 isa modification of the main switch of the invention, illustrating the inclusion of a third or intermediate contact position.

Throughout the views, the same references indicate the same or corresponding parts.

In accordance with the invention the switch A shown in Figures 1 to 5 is a two-way switch.

It is constituted by a plate I acting as support 50 for the contact- studs 2, 3, 4, 5, 6, and l.

A spindle l l supporting contact strips can turn in the centre of the plate and can make the strips assume the positions X (battery) or Y (dynamo). One contact strip 8 is riveted to the rotating 55 spindle H and can bring into contact the studs Figure 5a is an obverse view of a switch of Fig- 40 ure 5 showing the rear of two connections upon July 27, 1933 5 and 4 in the position X and the stud 6 and the spindle II in the position Y;

Another contact strip 9, riveted to an insulating washer l0, insulated from the spindle H and the strip 8, brings into contact in the position X the two studs 2 and 3.

In addition a sunk stud l is in permanent contact with the spindle l I and the strip 8=by means of a brass plate i4.

In the position Y of the contact strips (Figure 4) ,"the studs 6 and l are only in contact through the strip 8 and the spindle ll.

-In order better to understand the operation of the apparatus it is only necessary to refer to the diagram given in. Figure 5, and also Figure 5a which shows the obverse side of switch 20 of Figure 5. This switch may be made of a plate of molded insulating material supporting the brass or metal contact pieces b-c--dP-e f-g -h -i.

An axle 7' is in electrical contact with the connecting or contact arm n is rotatable in the center of the plate and causes the contact pieces to take various connections.

The contact pieces 71. and i carry spring and p,

which latter are insulated from each other by an air space, but said contact pieces 71. and i may be connected by means of the key 22 which is made of brass or any suitable metal and placed between the springs o and p which exert pressure on the key so that it is consequently wedged and elec-- trically interconnects said two contact pieces h and i. The latter contact i being connected to the wire 24 coming from the main control switch A and one of the wires from induction coil 23.

y of switch 20 and the contact h to which is connected the wire 21 communicating with contact I of the main switch A. The switch 20 is fed by the conductor 21. If the key is introduced between the springs o and p, the current is sent through the wire 24 and into the coil 23.

By manipulating the axle i, it is obvious that electric current may be supplied to the various lamps at the extreme right in Figure by causing a contact arm (not shown) to engage any one of the corresponding lower contacts in known manner within the range of said arm.

Returning now to the mentioned diagram, I5 is thetwo pole dynamo represented schematically by the collector, the brushes, the inductors I1 and the poles I6 which are constituted by permanent magnets. I8 represents the circuit-closer, I9 is the battery which is joined by a conductor 26 to the contact stud 4 of the special switch A forming the object of the patent. 20 is the switch The contact arm n makes connection between axle= switch A. The contact key 22 passes current to the ignition coil 23 and to the inductors H of the dynamo through the strip 9 and the connections 24 and 25.

The circuit-closer l8 has a terminal joined to the stud 5 of the switch A by the connection 28. A wire 29 joins the'dynamo directly to the stud 6 of the switch A. j In the case of battery ignition the operation is as follows:

The contact strip of the switch A being in the position X (battery) and the contact key 22 being placed in the switch 20, the inductors are under tension from the battery through the connections 28, 4,8; I], 21, 22, 24, and 25 and the contact strip 9. The dynamo operates with the magnets I6 and the supplementary inductors i1; It then chargesthe battery l9 through the circuit-closer, the wire 26 and the contact strip 8 joining the contact studs 5 and 4 of the switch A. The equipment then functions normally.

Let us suppose that the battery isshort-cir: cuited or damaged.

We then pass to the position Y of the switch A.

The strip 8,no longer being 'on the contact studs 4 and 5, then removes the battery 19 from the circuit. The inductors I! are also'switched out, thestrip '9 no longer being on the contact studs'3 and'2.

The contact strip 8 is then on the stud 6 and connects it to the'stud I. The dynamo is only operating on the magnets IS; The current produced by the dynamo is thus passed to the switch 20, which can supply current to the lamps and to the ignition coil, the accumulator battery being out of circuit.

andof suppressing the action of the inductors on the dynamo.

In Figure 6 a modification of the main switch is diagrammatically illustrated showing how three possible positions'may be assumed by the switching member for the purpose of avoiding overcharging of the battery. In the third position, the switch cuts out the inductors and the dynamo charges the battery, the magnets only producing the flux necessary for the operation of the dynamo. For thislpurpose a contact stud 3| is interposed between the studs 5 and 6, this being joinedto the stud 5. At the side of the stud 4 and opposite the stud 3| is located a stud 32 joined to the stud 4.

In this position (position Z, for weak charging); the dynamo operates only on the magnets IS, .the inductors being switched oif by means of the strip 9. The studs 2 and 3 no longer beingin contact, the dynamo then charges the battery with a weaker intensityo'f charge. To recapitulate, the device involves a rotary shaft ll, electrically connected to a lower contact disk l4,

rigid with a double contact plug 8 and another double contact plug 9 from which said shaft 8,086,099 controlling the lighting and ignition in the veis to say that the generator supplies the battery by the intermediary of the switch.

If the switch'is placed on the generator position, the inductors are cut from the generator and the battery is cut out of circuit with regard to the principal current; the generator then works in such manner that thecurrent arising in the armature rotating in the magnetic field createdonly -by.permanent magnets is immediately directed to the receiving apparatus, such as, ignition coil, lights, signaling, instruments,

As is obvious the invention is not limited to the sole methods for carrying out the invention given above solely by'way of example; .quite to the contrary it embraces all variations within the scope of the appended claims.
