body consisting of, the frame 2 and theside portion 3 rigidly secured thereto. The side portion 3 extends beyond the frame 2 to form the'protecting

flanges

4 and 5. The frame 2 is comprised of the front wall or part 6, the bottom wall and the top wall 8, the top and bottom walls being integral with the front wall. One side of the case 1s hinged at 9 to form a cover 10, and said cover extends beyond the frame 2 to form the protecting langcsll and 12 which eXtendbeyond the front wall and the top and bottom walls of said frame. The back of the casing is rounded as at 13, the hinge 9 being formedl down the middle of the said rounded portion. The top and bottom walls of they frame are rounded at their ends to fit the rounded portions of the side 3 and the cover portion l0. The hinge 9 joins the cover portion to the rigid side portion.-

Secured in the top wall ofthe frame, and

extending into the case, is a lamp socket 14 adapted to contain a lamp bulb 15.` Also secured to the top wall ofthe frame, adjacent the lamp socket, .is an insulating plate 16. This plate extends into the case and 1s slotted at its inner end,as'shown at.17. In y this slot is secured a contact strip 18 .by means ofa terminal contact pin 19 which passes through the insulating plate and through the contact strip. The head of the contact pin is adjacent to the front wall of l thecase and vis .rounded to adapt it to be engaged by la contact point, as will be more `Afully hereinafter described. The battery 20 is provided with the Ausual upstanding .con-

tact'point 21, which is adapted to lit in the slot of the insulating plate and to engage the contact strip therein.. The batteryns also provided with the spring contact polnt 22 which is adapted "to engage the lamp terminal 23, as shown. By means 'of the arrangement of the contact points and s trip described a considerable latitude of ad]ust ment is provided, so that the battery connections may be brought intoproper engagement with vthe terminals 1n the' case,

even though the batteries or battery termi*V nals may vary slightl in length. This avoids the necessity o springs forv malntaining thebattery contacts in engagement with the lampfterminals. Y

Slidably mounted on the inner side of the front wall of-the case is a contact plate`24,

which is provided atI itsl u per end with a v contact point 25 which isa apted to engage..

said stud being oblong in cross section. The

slot `28 in the front wall of the casing,

fthrough'which said stud extends, has two widthsthe upper portion 29 being broader than the lower portion 30. The upper portion of the slotis broad, enough to receive the stud whenthe button isturned' to bring the longer diameter ofthe stud transversely by the-length of the broader-portion of the ofthe slot. A In this position oli' the stud the shding movementof the button is limited slot. `The narrower portion of the slot is only broad enough to receive the stud when the shorter diameter of the stud is transverse of said narrow portion of the slot. In

ythis position 4of the stud the sliding movement ofthe button is only limited by the l,

entire length of the slot. It is, therefore, manifest that by` properly arranging the button the contact plate may be given a lshorter or longer sliding movement.

elliptical in shape and itis secured to the s tudin .such manner that the longer diameter of the". stud will be transverse of the button. By means-of this arrangement the ycontact plate will have its limited movement when vthe longest diameter of the button. is vertical, Iand said plate will have its longer movement when the longestdiameter of the button is transverse of the front wall of the case. The Contact pointand the terminal contact pin 19 are so arranged that they will be in engagement when the button is at the lowermost point of its limited movement, so that when the button is arranged with its longer diameter vertical the lamp circuitwill be completed when said button is Vforced downwardly to the limit of its movement, and said circuit will be .broken when the button is forced to the upper limit of its movement. The contact plate-is slotted jat its lower end, as at 31, to receive a guide v in 32 secured to the front wall of the casing. The contact plate springs 'inwardly sufficiently to hold the button frictionally `engaged with the front wall of the case, so that it will not be accidentally rotated.

On the edge of the Contact plate, close t0 the ved e of the front wall of thecase, are forme flanges 33, vone near the top of the case and the other Anear the bottom thereof. On the cover portion 10 of the case are secured two locking lugs 34, said lugs being spaced from the cover part a slight distance in order to permit the locking flanges to engage said lugs and lie between them and the cover.

The Y contact button 26 is substantially oval or two inwardly extending locking for shiftingthe contact plate operab The locking lugs and the lockingl flanges are so arranged with respect to each other that the flanges will be free of said lugs when the button has been moved downwardly to the limit of the narrow portion of the Slot, but will be engaged to lock the coverin its closed position when thebutton is locked in the broader portion 29 of ton is turned to permit the stud to pass down into the narrow portion of the slot, the locking flanges can be moved downwardly and freed from the locking lugs, thereby permitting the coverto be opened. From the foregoing it is manifest that the slidable button performs the double .function of a" contact maker andcbreaker and a lockoperating device. Thecontact performs the loilible function of a contact device and What I claim is:
