T cam member is mounted in a recess or chamber in the upper surface the lower member 2 and is adapted to be reciprmiated across the saine. the push buttons 5 extending through the oppositely dispesed alined grooves 6 at the sides of the chamber i9.y which are lo.E slightly less deep than the chamber 19', and

are provided with rounded 7oottoms to receive the push buttons.y The flanges on the cam member adapted to one; ge the. walls of the chamber lil so that these vvalls 3.3 establish the limits ot' travel of the cam member and the cam member in its movement across the between the limits of travel is arranged to expand a garter spring 21 which encircles the cam and is carried Within a .movable contacter 22V hereinafter described. Then the garter spriug'l is expanded and mores over the crest of the cam 1d Ythe cont-actor is thrown to one of the limits of .its travel in a recess 23 of substantially rectangular cross section in the lower hase member Q. ue to the provision of the spring :2l and the action of the cam 1G Athe contacter Q2 thrown with a quick snap action to make or break contact with .50 the switch terminals 3 located at oneend and against the .vall of.

of the chamber i the same. The upper hase member 'l is provided with chamber 2l or' substantially rectangular cross section in its lower surface which is adapted to lit over the chamher 23 in the lower hase member when the parts are assembled, but which is not quite as Wide or deep the chamber 253. This chamber o with the chamber 23 provides a suitable chamber for the swil'chcontactor and this latter is adapted to he reciprocated iv the com member from one side of this chamber -to the other. One ot 'the limits of the siitch contacter is established o v the walls of the chamhers 23 and 2li. in the lower 2. The recesses l tion shown in Fig. 2 for instance e left mand limit of travel is established oy these walls. The other limit of travel of the contacter is established by the contact terminals 3 :it the opposite side of the cha1n hers, These terminals 3 extend vertically upward through suitable parallel recesses in the tivo hase members l and 2 which extend through the chamber 23 and communicate with the chamber and serve the double function proiiiding the terminals for the switch mechanism and at the saine time providixig means ttor clamping the parts of the together. ln a preferred form these terminal members have long shanlis 'oi' suhstantially rectangular cross section and are provided with enlarged heads I5 at their upper ends which carry suitable binding screws QG, and are provided 'with laterali)7 disposed ears 27 on the opposite sides of the hinding screws. The upper ends of these terminals 3 are spaced apart by an insulating spacing strip 23 which is preferably seated in a recess 2S in theupper surface of the hase nieznher l. and formed of stamped insulating material and provided with rectangular' shaped perfor-ations or slots 3G which accurately tit the terminals. Since this strip 28 may he very accurately stamped, it serves to position the terminal memhers very accurately in the bases. The lower ends of the terminals 3 are preferably screw threaded as at 3l and extend into recesses l2 in the bottom surface of the communicate with each other through a recess 33 of reduced cross section, and an insulating spacing strip 34 similar to the strip 28 is preferably placed in position over the lower ende ot the terminals to position the latter in the same manner as described ahove. Taps 35 may he placed upon the threaded ends of the terminals 3 and these ends and the taps,

ily my improved constriwtion l have provided an improved switch in which the number ot necessary parts has been reduced by the use ot the terminal members as the moans t'oi' holding the base members in assembled relation. Further`r by the use ot the insulat'inggspaoing' strips for the terminal mem* bers l have been able, to very accurately position these terminal members in the switch.

y the provision ofthe spider support which is adapt-ed to he threaded on to the end ot a .standard fixture nipple, l have been able to provide a secury and stable .support for the switch mechanism and one which will permit oi screwinzgY the switch .support and the candle cup to the fixture at the same time so that the switch may be inserted ,without twisting the conductors.

HV the use of my improved push button switch mechanism l have provided a device which is peculiari)7 well adapted to use with lamps haring' fragile filaments since lh'.l i switch mechanism operates so smoothly that the filaments are subjected to no injurious shocks. Further, b v the provision oi the detachable push buttons Afor the switch l have provided a switch mechanism which may be readily' placed'in position in a slandard candle cup with the necessit)Y for boring' but two small holes on opposite sides o l the cup. and have thus been able to do away with the necessity t'or slottiug the cup and causing the. same to present an unsightly appear-ance. Further. by the use of the indicatinff push buttons the condition otl the switch may be determined at a glance.

By the provision of the improved socket support and the insulating washer l. am able to prevent the rattling of the candle and to provide an improved adjustable support for the socket adapted to use with candles of different heights.` By the provision of the stepped top of the upper base member l have also provided a device which is adapted to use with candles of various diameters. By the provision of the grooves in the sides ot' the bases l have provided ay device in which the conductors may t very snugly in the bases and be protected by the saine so that the switch is very compact and serviceable. Numerous other advantages of my improved construction will readily app ar to .those skilled in the art.

While'l have in this application described one specito form which mi' intention ma)Y assume in practice, lf haveonly described this Atorni as a means ot' illustrating the principle oi' in v invention and do not Wish tobelimited to this speeitic 'torni since my invention itseli. capable of assuming various other t'orms and ol: being widel)Y modified and adapted to various other uses.
