I illpplcaton filed `Tuly 24, 1926. Serial No. 124,634.
This invention relates to electric switches, and particularly to a combined switch and mounting for side wall fixtures. The purpose of the invention is to provide a simple compact switch which is applicable to a wide variety of side wall xtures, and which itself serves as an adjustable connecting means for mounting the fixture in place.
The switch is formed with a. body having a threaded tubular neckwhich is'clamped by means of a nut in an aperture through the front of the escutcheon plate forming part of the fixture. is rotary and tubular and thus offers a passage for a connecting screw which is inserted through the tubular `switch member, engages the rear of the switch body and is threaded into a special litting on an ordinary fixture stud. After the fixture is in place an actuating knob may be mounted on the forward en d of the tubular' stem, thus concealing the screw and affording a good grip for use in actuating the switch. y
The advantage of thel arrangement is that the switch may be assembled with the fixture. Vand electrically connected very conveniently and rapidly. after which the switch and life ture are fastened in place by merely inserting a screw through the stern of the switch the fixture tud.
`A preferred embodiment' isv illustrated in the accompanying drawings, in which- .Figure 1 is a perspective view of the fiX- ture having the switch attached.
Figure 2 is a vertical axial sectionon a larger scale.
and turning this into a fitting mounted on Figure 3 is a section on the line3-3 of' Fig. 2.
Figure 4 is a perspective view of the rotary switch contactor.
An ordinary fixture stud is shown at 6, and threaded on this is a. cap 7 to which the switch mechanism hereinafterY described is connected. The escutcheon plate or shell `of the side wall fixture is shownv at 8, and ob-v The movable switch elementY threaded thereon at the front of the escutcheon plate 8. The rear end of the shell 10 is outwardly flanged and connected to this iiange by means of bolts 13 is a retaining ring 14 which locks a circular insulating body 15 within the shell 10. The insulating'v body 15 supports the mechanism for a known type of snap switch which comprises four ratchet teeth 16 formed on the inner face of the insulating body andl opposed metal contacts 17 mounted in two of the ratchet teeth.
Binding screws 18 serve as a convenient meansfor connecting the lead wires 19'to the switch contacts.
Swiveled in the neck 11 is a tubular switch stem 20 which is formed at its, rear end with an enlarged head 21 for the purpose of preventing the stem 2O from moving outward throughthe neck 11. This head 21 carries a metal contactor 22'comprising an annular cup shaped" sheet metal member slitted to form two outwardly sprung contactor tongues 28.V The contacter 22 is pinned as shown at 24 to the head 21`of the switch stem 20. As the switch stem isturned clockwise the contactor tongues 23 snap simultaneously intor and out of contact with the contact 17. The switch unit lis connected with the cap 7 by means of a screw 25 which is inserted from the front through the tubular stem 2O and which enters a hole threaded' journal to centerA the switch stem 20. In the example illustrated the switch stem 20 is f shown as composed of insulating material.
but the onlj7 essential condition is that the stem be'insulated in some way from the contactor 22. A* l As stated, it is preferred to mount removably' on the forward end of the stem 2O an actuating button. A convenient way is to thread the stem 2O as shown .at,27 and to screw onto these threads an actuating button 28, but various other arrangements will sug gest themselves and may be used.
The mode of applying the switch is as fol-4 lows: The actuator button 28 and nut 12 are removed. All electrical connect-ions to the switch and fixture are made. The neck 11 is inserted through the aperture in the plate 8,
nut l2 is applied and turned Hush with the end of the neck. Then the screw 25 with its bushing 26 is inserted and the screw 25 is turned into the threaded hole in the cap 7 until the escutcheon plate 8 is drawn snugly against .the wall in proper position. actuator Jbutton is then screwed on and the work ot mounting is complete.
The important feature oi the invention is that the switch body is connected to the tixture and that the fixture and switch are connected to the stud by a screw inserted `from the front through a hollow actuator so as to' connect the switch to the stud. The addition of the actuator knob provides an attractive iinish and permits ready access to the screw on occasion. i
Obviously various switch may be used.

In an electric switch, the combination of a. casing provi-ded with switchingcontacts and having an aperture to receive a screw for fixing said casing in place; a rotary switching` element including a tubular actuator open at both ends and swiveled in a portion of said casing', the bore of said tubular actuator being` alined with the aperture in said casing, and larger than said aperture; and a bushing swiveledA in said actuator and having bore of substantially the saine size as said aperture, the parts being so con structed and arranged that said screw when inserted supports the bushingand the bushdiiierent types oi ing serves as a journal tor said tubular actuf ator.
4. In an electric switch, the combination The i of a casing provided with switching contacts and having an aperture to receive aV screw tor iixing said casing 1n place; a rotary switching element including a tubular actuator open at bothends and swiveled in a portion of said casing, the bore of said tubular actuator being alined with the aperture in said casing and so dimensioned as to permit the entrance 'of said screw; and an actuating' knob removably mounted on the outer end ot said actuator and serving to close the end ci the bore thereof.
ln an electric switch, the combination of a casing provided with switchingcontacts and having an aperture to receive a screw for lining said casing in place, said ,casing beingl termed with a reduced externally threaded neck axially alined with said aperture; and a rotary switching,- element including' a tubular actuator open atl both ends suf'iveled in said neck, the bore of said tubular actuator being so dimensioned as to permit the entrance of said screw.
6. ln an electric switch, the combination oi a casing provided with switchingcontacts and having an aperture to receive an attaching; screw 'for fixing said casing in place, said casing` being formed with a reduced threaded extension axially alined with said aperture; a rotary switching element including a tubular actuator open at both ends and swiveled in said threaded extension, the bore of the tube being larger than said aperture; and a bushing swiveled in said actuator and hava bore oi substantially the same'size as s Y, iL aperture, the parts being so constructed and arranged that the attaching screw when inserted supports the bushing and the bushing' serves as a journal upon which said tubular actuator is rotatably mounted.
7. In an electric switch, the combination ot a casing` providedwith switching contacts and having an aperture to receive a screw for fixing said casing in place, said casing being' formed with a reduced externally threaded neck axially alined with said aperture; a rotaryswitching, element including a tubular actuator open at both ends swiveled in said neck, the bore ot said tubular actuator being` so dimensioned as tol permit the entrance ot said screw; and an actuating knob removably mounted on the ,outerv end oit said tubular actuator and closing the boreV thereof.
