To all 'whom t may concern Be itknown that ,1, MONROE Gum'r, a.
citizen of the United States residing at and useful Improvement in Electric Switches,
of which the following is a speciiication.
This invention relates to the means em-l ployed for fastening switch contacts and terminal plates to'a switch support, such'as is shown in Patent No. 1,254,223 issued January 22, 1918,` from my application for which the present subject matter was separated.
The object of the invention 'is to provide an inexpensive and conveniently assembled means for electrically connecting the switch contacts with the terminal plates and at the same time and by the same means rigidly securing the contacts and plates to the switch support. p The invention is particularly adapted to small switches designed for low tension circuits which have metallic receptacles, and consequently the invention is illustrated and described herein as embodied in sucha switch.
Figure 1 of the accompanying drawings shows on enlarged scale a longitudinal section of a switch that contains an embodiment of the invention. Fig. 2 shows a transverse section of the same on the plane indicated by the line 2-2 on Fig. 1. Fig. 3 is a view looking into the receptacle, the face late, operating button and movable'switch lade being omitted. Fig. 4 is a view looking at the bottom of the receptacle -with the terminal plates in place. Fig. 5 is |a view looking at the bottom of the receptacle with the terminal plates and insulation removed. Fig. 6 is a view of one of the insulating disks employed on the inside and outside of the bottom of the receptacle. Fig. 7 is a view of one of the insulating vwashers which are placed in the openings in the bottom of the receptacle and lbetween the insulating disks.
The support of the switch illustrated is a receptacle 1 made of thin sheet metal with ears 2 extending outwardly from its open` end. In the bottom of the receptacle are two elongated perforations 3. Washers 4 of insulating material are located 1n the circular portions of these perforations, and inside and outside of the bottom and holding'the washers in place are disks 5 of insulating material. cularopenings 6 and four. angular open- 1n s v Ihe feet 8 of the conducting switch contacts 9 are seated 'on the insulatmg disk on the inside of the bottom of the receptacle. These feet have'central openings that aline 'with the circular openlngs in the insulating disks Each of these disks has two cirand notches 11 in theiredges that aline ,with
the angular` openings in the insulating disks. The terminal plates 12'I're seated on the insulating disk on the outside of the bottom of the receptacle. These plates have circular openings that aline with the circular openings in the disks and they have lugs 13 that extend through the angular openings in the disks and into the notches in the edges of the contact feet so as to prevent,any turning of one part with relation to the other.' These parts thus assembled are secured in place and the terminal plates and switch contacts are electrically connected by eyelets 14 that pass through the circular openings in the terminal plates, disks, washers and feet and are headed over at both ends. The eyelets are interiorly threaded for the reception of the binding screws that are employed for the attachment of the ends of the circuit wires. In this simple and cheap manner the switch contacts are connected in the circuit and are insulated from the metallic switch support and from each other.
The face plate 15 which is shown is stamped to the desired outline from thin sheet metal and is fastened over the open end of the receptacle by screws 16 which turn through 'the ears that project from the open end of the receptacle. The switch blade 17 is out from a thin sheet of insulation material of a width substantially the same as the interior diameter of the receptacle across by an eyelet 21 which is headed over' at both ends to hold it in place. All of the parts of this switch are easy to manufacture and assemble and the whole structure is very compact and well insulated.
The invention claimed is 1. The combination of a metallic switch support having openings therethrough, a perforated disk of sheet .insulation located on each side of the metallic support, metallic switch contacts with perforated feet mounted on one disk, perforated metallic terminal plates mounted on the other disk, said terminal plates being provided with lugs extending from said plates through the disks and feet, and metallic fasteners passing through the openings in said insulating disksplates and contacts and electrically connecting said plates with said contacts andl mechanically securing all of the parts together.
The combination of a metallic switch support having 'open-ings therethrough, a perforated disk of sheet insulation located on each side of the metallic support, metallic switch contacts with perforated feet mounted on one disk, perforated metallic terminal plates mounted on the other disk, said terminal plates being provided with lugs extending from said plates through the disks and feet, and interiorly threaded metallic eyelets passing through the openings iny said insulating disks, plates and contacts and electrically connecting said plates with said contacts and n'iechanicallyv securing all of the parts together.
3. rl`he combination of a metallic switch support. having openings therethrough, a perforated disk of sheet insulation located on each side of the metallic support, washers of insulation occupying said openings in the metallic support and held between the insulating disks, metallic switch contacts with end of the receptacle, a disk of insulation located on each side of the bottom of the receptacle, insulating washers occupying openings in the bottom of the receptacle and held between said disks, metallic spring fingers with feet mounted on the inside disk, metallic terminal plates mounted on the outside disk, lugs extending from said plates through the disks and feet, and interiorly threaded eyelets passing through said feet, disks and plates and electrically connecting said plates and said feet and mechanically securing all of the parts together,
5. The combination of a switch support having` openings therethrough, metallic spring-finger switch contacts with perforated feet mounted on one side of said support, perforated metallic terminalplates having lugs that extend through the switch support and contact feet, mounted on the other side of said support, and interiorly threaded metallic eyelets passmg through the openings in said plates, support and feet and electrically connecting and mechanically securing all of the parts together and preventing them from turning out of position.
