Be it known that I,- "ED'WIN VVATER URY, a

"citizen? ofithe United States, residing at Caldwell, in the county of Essexand State vv1'5 (Sf-New Jersey, have "invented certain ne and --useful: *Iin rovements 1n; Electric" 1 Switches, of-fwhic thefollowing is aspecificationJ i clectricswitch and seeks,-as one of-its principal objects,-to" provide a device of this fcharacteri wherein the-breaking of the circuit fthrough the switch will berendered more' safe and sure than heretofore by the i15 use T a -jmember fofliinsulating materi'al which niay -be proj ected between cooperat .iing contacts "of the-switch for separating said contactsj and insulating] the contacts F with respectto each'fothen I The'invention hasfas a "further object to provide. a switch fwhereinb'y employing a contact separating member of insulating materiahi'as previously "noted, "an efiicient" switch "of :fewer 2 parts "than heretofore em} 25 :ployed-may beproduc'ed while it-will also e-posjs'ible to manufactureswitches of a greaterivariety. 3

Y And the invention has a still further obj ect to provide a switch wherein the separat- 3 mg membenwill be automatically; locked at the end of its throw inopposite direc tions for maintaining the switch open or closed. 7 I

Other and incidental objects will appear hereinafter. I Y I I I i In the drawings: I -v Figure 1 is a longitudinal sectional view through myimprovedswitch, 7 Figure 2'is a sectional View similar to Figurel, but showingthe switch open. a V

Figure'6 is a detail plan view showing the open-and closed positions of the switch member. y X Y Referring now more particularly to the drawings it will :be seen that I employa base block or panel lO"whi ch is formed of suitable insulating materialgand, upstanding of notches which, for convenience, have been Extending through; the 7 lock 10 [spaced terminals 17 and 18 carrying-nuts said terminalss Thefterminal- 18 is formed with a; head' -2O partially"countersunk" in free end with the headj 2O of the terminal Y Application filed January 27, -1923.= 1 Serial no) 615,250; 1

Near one end thereof, the-top wall of thecover'is provided with a longitudinally directed slot '14 andformed in the cover at opposite sides of said slot are spaced pairs indicated at 15 and 16, respectively. Y are 19 at'thelowerside' of theblock whereby circuit wires maybe readily connected 'to' the base block'andmounted atone end upon the terminal 17 isa longitudinally bowed spring contact 21' normally-engaged at its l8,the head 20 being' provided with a fiat upper face against which the contactrests closing afcirci'iit between the terminals. As will be observed, said contact is provided, With an upwardly directed tip 22. Y I r Fitting between the top wall of'the cover 13 and the base block 10 is aswitch member 23 provided at opposite sides thereof with flanges 24 fitting beneath the flanges 11 of the base block slidably connecting the switch member therewith and projecting fromv the switch -member at the base thereof is a forwardly directed wedge shaped separating tongue 25. The switch-member is preferably of suitable insulating material so, that the tongue 25 is thus dielectric and formed in the upper end of saidmember is a trans verse recess or slot 26. Mounted upon the member is an operating button or knob 27 projecting freely through the slot 14 in the top wall of the. cover and provided with an oblong base 28 slidably, fitting in there'cess 26. Screwed or otherwise securedv to the base of the knob is a bowed spring 29 bearing at its'ends against the bottom wall of said recess pressing the button upwardly against the .top wall of the cover and formed on the upper side of the base to flank the knob are oppositely disposed V-shaped ribs 30 adapted to fit in the pairs of notches 15 and 16 selectively. -Thus,as shown in Figure 1, when the switch is closed,
