A. handle member 32 is provided on his headlights at the proper time. This concall member 28 and extends through the trol also makes possible the convenient opcasing for providing a convenient operating Ill) means for the switch. From the foregoing, it will be apparent that the plunger rod 24: may be reciprocated vertically against the resistance of spring 80 and that it. may also be moved radially about its swivel mounting); to cng:.1ge the end walls 33 of the apertures in plates 18 and 20 for ctl'ecting longitudinal movement of rods 16 or 17 in either direction. For example, as shown in the diagram in Fig. 4, it the handle be moved from the vertical to the position shown, one of the rods 17 would be moved longitudinally until .lug 22 thereon moved over boss 23 beneath it. overcoming the resistance or spring on the plunger rod. After the lug 22 passes over the boss 23, the action of spring 30 will retain the rod 17 and arm 12 beneath it in their relative positions until the handle 32 is again moved to return the rod to another position. By reference to Fig. 5, it will be apparent that it the handle 32 be moved. to a position 01" substantially degrees from the position shown in Fig. at, that one of the rods 16 and one of the rods '17 will each be projected forwardly so that the lugs thereon will ride over the complementary bosses and the switch will be in a position closing two selected circuits. It will also be apparent that regardless of what position the handle 32 may assume, it may also be pressed downwardly against spring 30 for completing another circuit, This last mentioned circuit will be main tained only so long as the handle 32 is held in a depressed position and is used for sounding a horn. The rods 16 and 17, plates 18 and 20, plunger rod 24: and casing 27, all being made of metal, may be conveniently grounded to a steering column 3% of an automobile so that the parts mentioned are simply connected with one pole of a source of electrical energy such as a battery or generatm'. These parts together comprise a movable contact; device. The various circuits to be controlled are then electrically connected to fixed contacts 35, 3G, 37, 3S and. 39. Each of the last mentioned contacts are provided with individual conductor wires 210 by means of suitable connectors 11 conveniently secured beneath the base member 10 so that conductor wires 10 may be brought through a suitable aperture such as 43 in the lower portion 27 of the casing from whence they may be carried through the hollow interior of the steering column 34. One pair of oppositely positioned contacts, for example 37 and 38, would be employed to control the bright and dim circuits for the head lights of a machine. Another pair of contacts 35 and 36 would be connected to control the right and left turn direction signal mechanism while the contact 39 would be used for the horn circuit. The switch may be conveniently mounted at the head of the steering column through the instruinentality of an annular flange 1 1 and set screw -15.

It will be noted from Figs. 1 and 2, that rods 16 are reciprocable in opposite directions to etl'ect electrical contact with iixml contacts or 36 and that the rods 17 are reciprocz'ible at right angles to rods ill in order to ell'ect electrical contact with either oi fixed contacts 37 and 38. The fixed con tacts just mentioned may be resilient in order to insure good contact with the rods. iii extending through contacts 35-3t3 and contacts 3738 are positioned on intersecting diameters, the intersection of which passes substantially over the center of central fixed contact 39.

The operation of the device as follows:

Assuming that the switch is mounted upon a steering column as shown in Fig. and the conductor wire l0 having been passed through the steering column, the various wires would be connected to the lights or mechanisms to be controlled in the following manner. Since movement of the handle 82 horizontally toward the right would cause rod 16 to form a contact with fixed contact 36, said contact would be employed to control a right hand turn direction signal. In the same manner, a circuit controlled by contact 35 would be completed by moving the handle 32 about its swivel mounting toward the left so that contact would be employed to control a left hand signal device. Movement oi the handle 32 transversely to the horizontal would eltcct complction of a circuit embracing either contact 87 or 88 so that these two fixed contacts would be employed to control bright and dim head lights. During the day time, a driver would have occasion to use only the horn signal and the lett and right turn direction signal. To sound a horn, he would merely depress handle by tapping downwardly upon it as is customary in sounding electrically controlled horns. Should the driver wish to signal for a right hand turn, he would push handle l1 n'i',:o1'1tally to the right thereby projecting the rod 16 to the left effecting a contact with fixed contact 36. As the spring 30 exerts constant downward pressure upon both rods 16 and 17, the said rod 16 would be retained in its position upon contact 86; the lug 22 and boss 23 sen-ling to preclude accidental separation. Should the driver wish to indicate a left hand turn, he would push the handle 32 in the opposite direction so that the contact 35 would be en gaged by the opposite rod 16. It should be noted that when driving at night, a driver would be called upon to have either the bright or dim head lights turned on at all times. Assuming that the .lixed contact 57 controls the bright head lights, the driver would move the handle directly toward him for closing the desired circuit and whenever lights were turned on, he would movethe handle to a position shown in 5, where in he would have completed the two circuits controlled by fixed contacts 36 and 38. By manipulating the handle to any of the eight possible positions, a driver may control either bright or dim head lights, left or right hand turn direction signals, or any combination of head lightintensity and direction signal. At the same time, the driver is also able to sound the horn by depressing the handle without moving the handle from its given position.

What I claim is:

1. In a device of the class described the combination with a. base, of a fixed contact mounted centrally of the base, of aligned fixed contacts mounted on the base equidistant from the central fixed contact, a casing for the base, a plunger rod mounted for swivel and reciprocating movement in the casing, a movable contact support mounted on the base and having an enlarged perforation in the center thereof, integral arms on the support extending in alignment with the fixed contacts, guide means on the arms, rods mounted reciprocally on the support means and extending between the guide means thereon, and yielding means operat-ively associating the plunger rod and reciprocating rous whereby reciprocating movement of the plunger rod may effect contact between said plunger rod and the central fixed contact and whereby movement of the plunger rod about its swivel mounting may serve to move the reciprocating rods to eiiect contact between said reciprocating rods and the other fixed contacts.
