This invention relates to electric switches used on automobiles and the like for placing under control of the operator the line connections between the spark generating means and the sparking terminals of the internal combustion en ines employed asa motive ower. And t e present improvement has or its object to provide a simple and eflicient structural arrangement and combination of transverse sectional elevation on line a:'-m,

the switch mechanism.
4 is an inner recess in the outer end of the frame 3 for the reception of a removable cover, plate (not shown to provide a closed lever and contacts hereinafter described.

ELECTRIC SWITCH.
985 701. Specification of Letters Patent.
vTo 0E whom-1M9 concern:
is adapted to span two of the stationary th tact points or plugs, now to be described.
8 are a segmental series of four contact plugs extending through the web 2, Withtheir front ends in the path of the upper end of the switch lever 7 and adapted for electric contact therewith, while theirrear ends are provided with screw extensions ada ted to receivethe bindin nuts by which individual line connections 0. the system are made to said plugs. r
The line connections above referred to will be that of-any of the dilierent sys-' toms of wiring generally used in automdbile ignition systems. In all cases, the central pair of contact plugs will preferably have connections so arranged that with the switch lever 7 in contact with said pair of plugs, the system will be inoperative, and the present invention involves means for locking the switch lever in the described inactive position against unauthorized manipulation, and to such end comprises a construction as. follows :*9 is a bolt sliding in a bushing 10 that extends through the web 2, aforesaid. The forwardiend of said bolt is adapted for engagement in an alined orifice formed therefor ,in the switch lever 7 as shown, while its rear end has operative engagement, by means of a circumferential groove 11 and elon ated slot 12, with aspring plate 13 attacied at one end to the rear face of the web 2 of the supporting casing 1, by a screw and bushing 14. The normal tendency of said spring plate 13 is to force the bolt 9 outward into engagement with the switch lever when not restrained angular bend, preferably of the V form shown, in the free end of the sprin plate 13, and16 is a guide bushin secure in the marginal frame 3 in longitu inal alinement with said spring end. and ada ted to provide a longitudinal guideway- .01 a remov able key or plug 17, the end of which is formed with a taper-head 18 adapted to en gage the aforesaid V shaped free end of the 0 spring plate 13 and rctract the bolt 9 from.
its locking engagement with the switch levelv 7 leaving the same free to bemanipulated b the operator as required, With the switc lever returned to its dormant or inactive po- 10%} sition, and the key or plug 17 removed, an
by means new to be described. 15' is an j of the spring plate automatic locking the switch lever Hirer; place. l 19 is a gap in the bnttnm portion of the l marginal frame 3, in which the switch lever i '5 s and 1S limitedln its throw.
saving thus fully described my mid in vention What I claim as new and desire to 1 eeenre by Letlers Yatent, is: l
l. in a switch of the character herein deserined, the combination of n supporting base, a segmental series sf stationary eon- .nct points arranged on said base, a mnvable l l svith lever pivoted on said bae, and means i in! locking sail lever in a dot-mam positien, the same comprising a bolt Slldll'lg said. 3 base and engaging an orifice in said lever, l spring plate eiwaging :nid belt and yieldingly holding the sameto its engagement-i with the switch lever, and n bushmg secured to the base in longitudinal alineinent with said spring plate and adapted to guide plug lnn' itucllnelly in engage the free end l and move the bolt Out of l engagement with the l switch lever, substantially as set forth.
l n n switch of the character herein described, the combination of a supporting base, a. mgmentnl SEI'lES of stationary con tact points arranged on said base, a movable switch lever pivoted on said base, and means for locking said lever in a dormant, position, the same comprising a boltslidin in said base and enga ing an orifice in sai lever, a spring plate armed with an angular free end and having engagement with said bolt in yieldingq hold the same to its engagement with the switch lever, and a bushing secured to the base in longitudinal alinement with said spring plum and adapted to guide a, lug longitudinally to engage the angular tee and of the spring plate and release the switch lever, substantially as set fort i;
