Lib-ail whom it Hwy coneern Be it known that I, GERALD N. I" e citizen of the United States, resiciing at T ford, county of Hartford, Connecticut, have invezited certain new and esefui Improvemeiits in Electric Switches, ofwhich the ioiiowiiig is; 2,1311 clear, and exact description. My mvention reiet-es to improvements in electric switches, and giartieuieriy wish-but ton snap-switches.

is to construct 1 The object of the in vention a switch ot tms chem otter which Wiii o, ei'e'te positiveiy and accurately Without binding of aka the parts or undue iost motion,

4 The principles of. the invention are iiiustreated in the accompanying eingie she V of drawings. Briefly stated, it compris s the employment of av tilting operating memee'a and a push-button extending through en. opening iii-the face-plate and ooniiecteai to tEe operating member by e double pin-andsiot engagement, so that the button has substentially a straight-line movement pergaendicuiar to the face-plate.

A. t e of switch to Weich the invention. pertieuier'ty adapted is shown in my former patent, No. 645,092, dated March 13, 196%.

The operation of the tilti ber 7 can. es the blade 3 to be soap (1 into and out of engagement with the eontaetfi.

The invention is equally eppiiceiiie to time pie-pole switches.
