To all whom fit may concern: the pole carrying plate 7. This pole carry- Be it known that l, JOHANN GODFREY ing plate is stamped to shape, preferably of PETERSON, a citizen oi the United States, l, steel, andwhen formed its side edges are bent residing at Hartford, in the county of Hart i upwardly atright angles to the plane of the ford and State of Connecticut, have invented i plate so as to form arms 8. When the a new and useful Snap-Switch, ot' which the handle is turned, the spring 9 is placed under following is a speciiicaton. tension by reason of the engagement of its This invention relates to the construction upper end with the shoulder on the washer electric switch. 1U that is fastened to the spindle and the enthe invention is to provide gagement of its lower end with one of the aims that are turned up from the plate. After the stop plate has been disengaged from the ratchet teeth by any common means, the pole carrying plate is thrown violently by the spring.
ol a rotary snap he object of rotary snap switch, by means of which the movable contacts or poles, whether a single plate or two plates, can be easily and quickly mounted upon and, il' desired, perfectly insulated from the pole carryingr plate, which is thrown by the actuating mechanism at the proper time, which pole carrying plate is also constructed so that it may be utilized tooperate an indicating dialer shutter.
the ino-.able poles consist of a pair of thin spring metallic plates 1l. In mounting these it is preferred to first slip a metallic washer l2 upon each of the arms, then lace an Figure l of the accompanying drawings insulating washer 13 on the metalpwasher, shows a side elevation, with the base cut in l then the plates with the bushing 14 which central section, of a switch embodying this prevents metallic contact are slipped u on invention. Fig. 2 the arms, after which an insulating was er shows a similar view looking from` another side. Fig. 3 shows a l5 and a metallic washer 16 are placed on the vplan ofthe pole carrying plate and the poles. arms abo'.'e the plates. After these ieces Fig. 4 shows a side elevation of the pole are in position, the arms are expan ed or given a blow with an instrument to cause them to slightly spread and secure the parts together. As shown in Fig. 7, the movable contact or pole can be' formed of a single plate 17 instead of a pair of plates, if desired. in this case the plate is mounted the same way upon the arms that project up fronl the ole plate. The insulating washers and ushings can be omitted if it is not desired to insulate poles from the pole carrying plate. The arms which project from the pole plate are preferably made of sufficient length to extend upwardly and engage an indicating dial or shutter 1S of common form as indicated in dotted lines in Fig. 2. Ii' the dial or shutter is not to be used the arms could of course be made shorter, but it is preferred to have them of l'ull length so that the dial can be used, il desired.
