n@ d??? @y Patented Nov. 22, 1932 PATENT OFFICE HUGH W., BATCHELLEB, O1? WORCESTER, IASSACHUSFITS TOGGLE SWITCH Application iled September 1L 1931.

@i the accompanying drawing formingl aA is part oi tbis specification,-

Figure l is a front view of a switch ein the invention Figure 2 a rear view Figure an edge view., n liigiure is a section on line fir-4 of Fig- L 2 i igure in' a section on line 5-5 of Figure 27 showing tire on7 adjustment of the re i5 an enlargement of a portion oi a e i? siiowing the nii adgustnientq ie'ure i is a pempective view or the nand is a rear view ont a differently i embodying tbe invention an edge view partly in section oli tno Itch shown by Figure lil so l2 a section on line i2l2 of?? d Tire same reference characters indicate tbe same parts all of the iiguresn casing portion of the switch shown by s@ Figures l to 6, inclusive, is composed of two members9 vin i' a sheet metal front member including a central facing 12 having a lever receiving orifice 17, and insulator attaching means projecting inwardly from said facingg and a. one-piece insulating member or insulator 13 engaged with said attaching means and spaced thereby from the facing 12.

The attaching means is preferably integral with tbe facing, and in this instance is embodied in ears 'la bent inward from the oppo Serial No. 562,232..

site edges of the facing, and seated on the insulator, and spacing the latter from the fac ing, and prongs 1:5 integral with the ears 14 and inserted in slots in the insulator and clinched on the inner side thereofn The casing may be attached to a wall or other support by integral extensions or ears 16, on the acing 12.

The facing l2 and the insulator attaching means when integral with each other may be 6o made in one piece which is so formed that it may be stamped froml sheet metal, and is adapted to engage a one-piece insulator,

The insulator is provided with an orilice 1 8 alined with the orifice 1i iu the facing 12, c5 and is also provided with terminals 24 and 25 insulated from eaob otherand attached to the insulator by screws 2d The terminals are separated by a gap within tbe orice i8.. The terminal. 24 bas an end portion 24a pr@ 70 jecting into tlie critico i8? and tbe termina-l 25 bas a resilient end portion 25a also pro jecting into said oriiice, cacio 'terminal baving prongs :'28 inserted in insulator and clinched on tbe inner side iitiereo The facing orifice l@ aoguiar and preferably square.J as ubest shown by Figure l@ designates a preerably onefpiece switch lever insuising material suoli as balielite o Said lever entends tiiroangie.9 is oscillatto able in orioe i8 and has an angular cross section conforming to the angular margin oi said oriiicew so that tire liever is prevented from turning on its longitudinal axis in said orioe9 and tbereiore can oscillate only in a se predetermined patio..

Tire lever i9 is provided with preferably integral iulcrum stads 2@ projecting from 'two oi its opposite sides, and in rocking con tact "with the inner side of the facing l2. Said projections are so arranged that the lever bas a longer outer arm and a shorter inner arm, as best shown by Figure 'L The lever has a longitudinal guiding recess 22 extending tlirougb tbe shorter arm and into the longer arm, the ulcrum studs 20 being wholly on the exterior of the lever so that the recess extends between said studs into the longer arm.,

A gap bridging conductor 21, preferably a 10 metal ball, is movable in the recess 22. An elongated helical spring 23 is seated on the inner end of the 'ding recess and presses the conductor against both of the terminals 24 and 25 to close the ga when the lever is in the position shown by igure 5,and against the terminal 25 to leave .the gap oien when the lever is in the position shown by igure 6.

The described elongation of the guiding orifice 22 permits a corresponding elongation of the sprm 23, so that t e spring reacts on the inner en of said guiding orifice when the conductor bears on either, or both of the terminals, with suicient force to hold the fulcrum studs 20 firmly against the inner side of the facin 12, and thereby prevent any possibility o loose movement of the lever.

The casing portion of the switch shown by Figs. 10, 11 and 12 is also composed of two members, one being a preferably one-piece sheet metal member, and the other a onepiece insulator. Said casing portion is adapted to be detachably secured to a su port such as the dash of an automobile, an v used, for example,for controlling a circuit which operates a dome li ht or a cigar lighter.

yIn this embo iment of the invention the insulator attaching means is preferably integral with the facing (here designated by 120) and is embodied in a base pre erably integral with and surrounding said facing.

Said base includes a marginal portion 121 having a fiat inner side on which the insulator 130 bears, as shown b Figure 12, a rim portion 123 bearing on t e margin of the insulator, and ears or prongs 124 on the rim portion bent inwardly upon the outer side of the insulator. l An annular portion 122 of the sheet metal of which the facing and base are formed, oisets the base portion 121 from the facing 120.

The base portion 121 is provided with an i extension'12la (Fig. 11) projecting above the insulator and constituting a fixed clamping jaw adapted to bear on one side of the support a, and adapted also to support the bracket next described.

Said bracket includes an inner end member `127 bearing on the extension 121@ and held :againstA the latter by the rim portion 123, and ears 128 (Figs. 10 and 11) formed thereon andjbent over the outer side of said bracket member. An arm portion 126 of the bracket member projects as shown by Figure 11, and has an ear 129 at its outer end containing a tapped orifice. A clamping screw 125 is engaged with the ear, and is adapted tobear on the opposite side of the support a, said screw constituting another clamping jaw. A s

Downwaid displacement of the bracket from the position shown by Figures 10 and 11 is prevented by two of the ears 124, the

under side of the arm member 126 bearing on l said ears.

The last described embodiment is provided with the terminals 24 and 25, the switch lever A19, the conductor 21, and the spring 23, all

insulator engaged with said attaching means and spaced thereby from the facing, said insulator having an orifice alined with the facing orifice; terminals attached to the insulator and separated from each other by a gap adjacent the insulator orifice, a onepiece switch lever extending through and oscillatable in the facing plate orifice and having an angular cross section conforming to the angular margin of said orifice, whereby the lever is prevented from turning on its longitudinal axis in said orifice, said lever having fulcrum studs projecting from two of its opposite sides and in rocking contact with the inner side of the facing, said projections being so arranged that the lever has a longer outer arm and a shorter inner arm, the lever having a longitudinal guiding recess extending through the shorter arm between said fulcrum studs and into the longer arm, a gap-bridging conductor movable in said recess, and an elongated helical spring seated on the inner end of said guiding recess and pressing the conductor against the terminals, and the fulcrum studs against the inner side of the facing, the lever being movable to cause the conductor to close and open the gap between the terminals.

2. A toggle switch as specified by claim 1. said facing and insulator attaching means being made in one piece from sheet metal.

A toggle switch as specified by claim l. said lever and its fulcrum studs being made in one piece from insulating material.

toggle switch as specified by claim l, said insulator attaching means including a clamping jaw portion having means for securing a bracket member thereto.

i In testimony whereof I have ailixed my signature.
