lowing is a specilication.

This invention relates to the construction of a receptacle for a single-pole push-button i electric snap switch.

The object of the invention is to so construct such a receptacle that it will be easier to manufacture, .stronger and less liable to be broken while being made and in use,

simpler to wire.l and have less necessity for the provislon of an insulating cover for ex- Pclnding dust and dirt. than the receptacles in common use for such switches. This receptacle, as a result of its novel construction, is smaller in size, and thus requires less material in its manufacture, can be put into a smaller metal wall box. and be packed in smaller paper cartons and wooden boxes,

consequently taking less space for storage,

is lighter in weight, thus facilitating handling and transporting. and reducing freight-charges. and enters a smaller hole in a wall, therefore making it much cheaper and more satisfactory than the prior receptacles used for the same class of switches.

Figure 1 of the accompanying drawings shows a plan of a push button switch recep-v tacle which embodies this invention, containing a. single-pole push-button switch mechanism. Fig. 2 shows a plan of the receptacle with the mechanism omitted, but with the fixedl terminals in place. Fig'. 3 shows an end elevation of the receptacle. Fig. L1 shows a central transverse secgion of the same. Fig. 5 shows a longitudinal section on the plane indicated by the dotted line 5 5 on Eig. 2. Fig. 6 shows a bott-om view of the receptacle.

The receptacle which forms the subject of .this invention is desirably made of porcevent the entrance of dust and dirt into the interior. The bridge plate is a part of the frame that supports the single pole switch mechanism S. This mechanism is of a common type, and is actuated, by pressing` the push buttons 9, for oscillating the movable pole plates 10 into and out of engagement' with the fixed contacts 11.

The fixed contacts are a part of the terminals .12 that are securedin recesses in the end walls near one side of the receptacle.

The bridge platev These terminals are held in position byscrews 13, which pass through perforations in the bottom of the receptacle and into threaded perforations in the lower bent ends lil of the terminals. The upper vbent ends 15 of the terminals have threaded perforations, and in thescturn binding screws 16, which are employed to fasten the ends of the circuit wire. terminals also have lugs 17 for the purpose of preventing the ends of the circuit wire from slipping from under the heads of the binding screws, when the screws are tightened for the purpose of securing the wires. The outer surfaces of the end walls on one side of the middle have shallow grooves 1S to provide for the free passage of the circuit wire, and the upper edges .of .the end walls at the top of these grooves on one side of the center, are cut away, as at 19, so that the ends of the circuit wire may be readily bent over and'secured to the terminals in the interior by the binding screws.

The upper ends of thev the opening in thetop, leaving only so much opcn as will allow the ends of the circuitwire to be fastened conveniently. This and the objects and incident advantages previously recited, result from the features of construction which enables the bridge plate,

carrying the switch mechanism, to be located on one side of the middle line of the receptacle, and the ends of the circuit Wire to be brought up and bent ovei in on the other side| of the middle.

The invention claimed is:

1. A snap switch receptacle having end Walls, side Walls and a bottom Wall,`said end Walls having provision on one side of the middle for the-attachment of a bridge late, and on the other side of the middle iiaving provision for the entrance oitl the ends of a circuit Wire.

2. A snap switch receptacle having end Walls, side Walls, and a bottom Wall, said end Walls having provision on one side of the middle for the attachment of a bridge plate, and on the other side of the middle having provision for the attachment of fixed contacts.

' 3. A snap switch receptacle having end walls, side Walls, and a bottom Wall, said end walls having provision on one side of the middle for the attachment of a bridge` plate, and on the other side of the middle having provision on the exterior for the entrance of the ends of a circuit lWire, and

having provision on the interior for the attachment of fixed contacts.

4. A snap switch receptacle having end Walls, side Walls, and a bottom wall, said 'end Walls having provision on one side of the middle for the attachment ofV a bridge plate, and on the other side of the middle having' provision for the entrance 0f the 35 ends of a circuit Wire, and for the attaclhl 'ment of lixed contacts, and one of said side Walls being shaped to closely fit the edge of abridge plate.

5. A snap switch receptacle having a bot- 40 tom wall, side Walls and end Walls, with the upper edges of said end Walls on one side of the middle of the receptacle provided with mortises for receiving a bridge plate, and with perforations for the passage of bridge plate fastening screws, said end Walls having on the other side of the middle Wire grooves on the exterior, terminal recesses in the interior, and openings in the top edge from said grooves to the said recesses.`
