To all whom it may concern:
Be it known that i, DAvn) RoBERTsoN BRUCE, a citizen of England, at Redhnrn Terrace, ionth street Ponders End, London,inthe conntyof Middles zfitngland,
have invented certain new and n ful improvements in Electric Swi ches, of which the following specification.
My invention relates to electric swiiclies so arranged that by the movement of a, lever the contacts suddenly made and broken and cannot accidentally e their post tion, this r quires some force to be applied to the lever.
The mecha ism of switch my inventio may be arranger on able for fixii inst a oi elevations with cover remove contact broken i.
. l, respectiv- 8 show a hump-holder elevation,
angles to showing contact broken and ing contact made.
'm'o metal o ducting-wires c (o o presenting toward each oth A lever d, pivoted near one hat. a slot engaging apin which projects downward into 1; "rom a piece 6 of non-condnct-- ing material. On one end of the piece :2 is fixed the middle portion of an elastic metal stripf, or several of these, bent i-o i l form and having pivoted in their lirn s rollers g, which run along the vertical face of two up- Wardly-projectin. s on-comln ing base, these I rounds the parts '1 the limbs off spring apart making sudden contact with the faces of the metal pieces a a, as shown in Fig. 2, the strips j" then forming a bridge along which the current passes from the one Wire 0 to the other. The mechanism is covered by a cap 7c, screwed on the base.
the switch is made in two halves land m, held together by a ferrule 11 at the one end the lamp-socket p at the other end, both the parts Z and m being made of non-conductins material and being; provided with the usual spring plunger-contacts q. As in the construction first described, a lever (1 moves a piece 6, having on it spring-strips f, with their rollers g, which bear against the faces of prominent parts h of the halves l m of the i snlatingcase. Oneofthecondnoting-wires .2 iecied to a contact-plate r. The ire c is connected to one of the plunntacts q, the other plunger (1 being conie a contact-plate 5. When the lever v t .e stripsf form a conductbetween the contact-plates 1- and tons the current from the one Wire 1 by r and f to s, thence by one of the pliing'ers to the filament of the lamp, to the 1 plunger q, and the other Wire 0. av n thus described the nature of this and the best means I know of carhe same into practical effect, I claim- 11 electric wall-switch comprising a le- 11; piece e carrying an elastic conductor to L for with rollers g mounted in nos a or ihctal contacts a and an atii'ig-base I) having upwardly-projecting curved carts Ii along which the rollers g 2. An electric switch having a slide carrying an elastic conductor arranged in I form and provided with rollers, cam-faces engaged lfy the rollers, and a pair of metal contacts engaged by the conductor in certain positions of the slide; snbscantially as described. n testimony whereof have hereunto set eamfl in presencelof two subscribing wit- .ch d connected to an insulating run, substantially as described.
