ELECTRIC WALL SW ITGH.

Original application filed March 2, 1923, Serial No. 622,352. Divided and this application filed September This application is a division of my copending application filed March 2,1923, Ser.

No. 622,352, filed in accordance with the requirement of the Patent Office to divide the subjectmatter of this application from said parent application.

My invention relates to an electric wall switch in which the contacts are operated with a quick, positive snap.

In the accompanying drawings the same reference numerals refer to similar parts in the several figures.

Fig. 1 is a vertical section on line 1-1 of Fig. 2 of my wall switch;

Fig. 2 is a face view of the wall switch taken on line 22 of Fig. 1.

In the illustrative embodiment of my invention my wall switch 1 is mounted in a recess 2 in the wall 8. The porcelains or insulating members 4 and 5 are mounted within the metallic box 6 as is the usual construction. The porcelain members 4 and f are provided with transverse grooves which. when placed together, form bearings for the axle or arbor 6 upon which is mounted the driving member 7 which is a lever. This lever extends through the slot 8 in the bridge plate 9, the actuating arm 10 of the lever being covered with insulation 11. The driving arm 12 of the lever 7 is provided with a convex portion 13 which engages with the spring arm 14, having a corresponding convex contact surface. This spring arm 14 is connected to, and is prefen ably a partof, the driven contact member 12 which is also mounted upon the axle or arbor 6. In this form of my invention the (ontact driven member is adapted to make and break the electrical connection between the fixed

electric contacts

16 and 17.

(.lnc of the wires 18 is connected to the binding post 19 and is in electrical connection with the electrical contact 16. The other wire 20 is secured by the binding screw Serial No. 739,500.

21 so as to be in electrical connection with the electrical contact 17.

-The two porcelain members 4 and 5 are secured together by the securing screws 22 which screw into the bridge plate 9, This bridge plate is provided with

extensions

23, 23 having openings for screws'24, 2a, which secure the face or escutcheon plate 25, the bridge plate 9 and the metallic box 6 to the wall or other suitable support by passing through holes in the

flanges

26, 26 in said box. P

In the drawing the contacts are shown with the current on. To cut the current off it is merely necessary to press down upon the end 11 of the lever 7 and cause the convex member 13 on the driving arm of said lever to move upon the convex member on the spring arm 14; of the driven member 15. This will then cause the two convex surfaces to snap by each other, and will cause the contact driven member 15 to snap away from the fixed

electric contacts

16 and 17 and engage with the stop 27 thereby breaking the current. To again connect the circuit it is merely neccssary to press up on the end 11 of the lever 7, when the operation will be reversed, and the contact driven member will spring back with a snap into contact with the fixed

electrical contacts

16 and 17 and again assume the position shown in Fig. 1.

It will be seen that my electric wall switch is simple, made of few parts, that it can be cheaply manufactured and that the electrical connections will be made or broken by a quick positive snap.

Having thus described this invention in connection with an illustrative embodiment thereof, to the details of which I do not desire to be limited, what is claimed as new and what is desired to secure by Letters Patent is set forth in the appended claims.

hat I claim is 1. In a wall electric switch the combinatron of an axle, two electrical contacts, a

rocking contact driven member mounted on the axle and adapted to connect said contacts, said rocking contact driven member being provided with a. yielding armhaving a convex operated surface, an operating le ver mounted on the axle and having an actuating arm extending out from the wall switch and a driving arm provided with a convex operating surface mounted within the wall switch adjacent to and in cooperation with the convex actuating surface on the yielding arm of the rocking contact driven member, the rocking of the lever being adapted to make and break the current in the wall switch.

2. In a wall electric switch the combination of two electric contacts, a rocking contact driven member to connect said contacts, said contact driven member being provided with a fixed convex actuated surface, and an operating lever provided with an actuating arm and a driving arm, the driving arm provided with a convex operating surface adapted to contact with and actuate the fixed convex surface of the rocking contact driven member.

In a wall electric switch the combination of two electric contacts, a rocking contact driven member to connect said contacts, said contact driven member being provided with a fixed convex spring actuated surface, and an operating lever provided with an actuating arm and a driving arm, the driving arm provided with a convex operating surface adapted to contact with and actuate the fixed convex spring surface of the rocking contact driven member, stops mounted on the driving arm and on the rocking contact driven member to limit the throw of the cooperating convex operating surfaces.

l. In a wall electric switch the combina tion of an axle, two electric contacts, a rocking contact driven member mounted on the axle and adapted to connect and disconnect said contacts said rocking contact driven member being provided with a sheet metal yielding spring arm having a convex operating surface, an operating sheet metal lever mounted on the axle and having a sheet metal actuating arm extending out from the wall switch and a struck up sheet metal driving'arm provided with a convex operating surface cooperating with the convex surface of the sheet metal yielding spring arm.
