SWITCH.

. Specification of. Letters Patent.

Application filed February 12, 1916. Serial No. 77,900.

To all whom it may concern:

. Be it known that I, GERALD F. HAINES, a citizen of the United States, residing at Cape Cottage, in the county of Cumberland and State of Maine, have invented new and useful Improvements in Switches, of which the following is a specification.

This invention relates to switches and has for its primary object to provide a construction by means of which a branch circuit may be tapped on to a main circuit.

An object of the invention is to provide a switch by means of which a branch circuit may be connected to a main circuit.

Another object of the invention is to provide a switch all parts of "which are so related that excessive sparking therebetween is prevented. I

With these and other objects in view, the invention consists in the construction combination and arrangement of parts as will be hereinafter more fully described illustrated in the accompanying drawing and pointed out in the claim hereunto appended.

Referring to the drawing :Figure 1 is a side elevation of the invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a horizontal section on the line 33 of Fig. 1. Figs. 1 and 5 are diagrammatic views.

In the drawing the numeral 1 designates a base of insulating material in which is slidably mounted a plurality of contacts 2, constantly forced toward each other by means of coil springs 3. Arranged in a circular depression 4 between the contacts 2 are the arcuate contacts strips 5 mounted in a disk 6 of insulating material. The disk 6 is mounted for rotation upon the bolt 7 mounted in the base 1. The disk 6 has secured thereto a knob 8 by means of which the disk 6 may be mani ulated. To complete the switch, I provi e a casing 9 covering the electrical connections.

In Fig. 4, I have illustrated the switch in a position to allow current to pass from the main circuit 10 to the branch circuit 11,

whereas in Fig. 5, I have shown the switch 1n another position for establishing the continuity of the main circuit and interrupt- 1ng current flow to the branch circuit.

By having the switch formed as set forth, I am able to cut in a branch circuit upon the main circuit or to cut out the branch and reestablish the continuity of the main circuit and to perform these actions without excessive sparking. From the foregoing description contained 1n connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art of which the invention relates and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereto, I desire to have it understood 'that the device shown is merely illustrative and that said changes may be made when desired as are within the scope of the claim.

What I claim is A switch comprising a base, arcuate spaced contacts mounted in said base to slide toward the center of said base, springs housed within the base and acting upon said contacts, a disk mounted for rotation in the base with the peripheral surface thereof limiting the movement of said contacts toward said center, and arcuate contact strips embedded in the peripheral of said disk and each of a length great enough to bridge the distance between two contacts in any position of said disk.

In testimony whereof I affix my signature in presence of two witnesses.
