new and useful Improvements in Contact Devices for Switches, of which. the following is a full, clear, and exact description.
The invention relates to snap electric switches, and particularly to theconstruc tion and mounting of the movable contacts rotary and push switches.
The objectof the invention is to provide a pole plate and a mounting therefor, which is equally applicable to either single or mulswitches of both the rotary and various positions with respect to the actuating mechanism to provide the necessary movable contacts for the Various types of switches, without altering the construction of, the plate and mounting for the several types of switches with-Which they are used.
While the pole'plate an'dmounting therefor, which form the "subject ofthis invention, are applicable, without change, to the actuatingmechanism of eithera rotatory snap or push snap electric switch, the invention is illustrated herein only as applied to the actuating mechanism of a rotary snap switch.
Figure 1" is a plan view of a rotary snap switch mechanism provided with a pole plate and mounting constructed according to this invention.- Fig. 2 shows a central vertical section of the same, on, the plane indicated by the dotted line aa on Fig. 1. Fig. 3 shows on larger scale, a section on the plane indicated by the dotted line b-b on Fig. 1.
Fig. at shows a plan of the pole carrying or spring plate. Fig. 5 shows an edge view of the same. ig. 6 shows a plan of one form of movable contact or pole plate in full lines, and shows in dotted lines the same plate or another plate arranged in reverse posiplates lie in a double poleswitch. Fig. 7 shows an edge view of the plates showninFig. 6. Fig. 8 shows a plan of an insulating piece that may be used for separating the movable contacts or pole plates when arranged as indicated in Figs. 6 and 7.
The base 1 of the switch illustrated in the drawings, is formed of'insulating ma- JorrNA. YORK, 21 citi- "other end with tcrial, such as porcelain, and has a centrally arranged spindle 2 provided with a button 3, by means of which the spindle may be rotated and the actuating mechanism operated. The spiral spring 5 has one end connected. with the spring plate hand the the handle 3, in the usual manner, so that turning the handle puts the spring under tension, andat the proper tnne throws the spring plate which carries the movable contacts or pole plates. As the actuating mechanism and locking and release mechanism form no part of the present inventiomthey are not illustrated and described in detail. Any common form of actuatin and lockin mechanism ma be used.
The spring plate 4, which is shown, has a central hub through which the spindle extends, and about which the spiral spring is coiled. lhis plate is shown. as provided with lugs 8 and 9, which are bent up from the edges of the plate for the purpose of supporting the pole plates. at right angles from diametrically opposite sides of the center of rotation and have shoulders 10 which form a T680 for the pole plates and the insulation therefor.
' The switch illustrated iii the drawings has two pole plates 6 and 14:, which poleplates have the same configuration. Each pole plate has contacting or brush ends 23 and 24, which are offset from and extend in a These lugs extend plane parallel with the plane of the body of the pole plate. In the center of each plate is a circular opening 26, connecting with.
which are openings 27 and 28. These openings are arranged so that the axis or greatest length of the space in the body of the plate, extends at an angle of substantially 45 degrees with the longitudinal axis of the pole plate, as shown in Fig. -6. As a'result of this construction, when two pole plates are placed together with the longitudinal axes the same, or with the longitudinal axes at right angles, the openings in the plates coincide, as indicated in Fig. 6. When a double pole switch, such as is shown in the draw ings, is made up with pole plates having this construction, it is preferred to first place a metallic plate 11 on the lugs'8 so as to rest upon the shoulders 10. This plate is insulated from the adjacent parts by a washer 12 of insulating material and is insulated other.

The pole plate 6 above the washer 19 is identically the same form as the pole plate 14, but is placed in a reverse position so that the axesof the two plates extend at right angles with each Above the pole plate 6 is an insulating washer 21 and above this is arranged a metallic plate 22, which preferably-has the same form as the bottom plate 11 Insulating pieces 16 of the shape shown in Fig. 8
are placed in'thelopenings in the pole plates 6 and 14: to insulate these pole plates from the supporting lugs. When the parts are over to secure them together.
The invention claimed 1s:
' a In an electric switch in combination with the actuating mechanism, a spring plate, two supports projecting from said plate at right angles thereto, a pole plate' with brush ends extending outwardly. therefrom, said ole plate having an elongated opening, the ongitudinal axis of which extends at an angle of substantially forty five degrees with the longitudinal axis of the sulation mounted on sai cated in the ends of said opening on opposite sides of the longitudinalaxis of the pole plate.
