To all whom it may concern:

Be it known thatl, ARTHUR HADDOOK, a' citizen of the United States, residing at East Orange, in the county of Essex, State of New Jersey, have invented certain new and of which the following is afull, clear, concise, and exact description.

This invention relates tocontact terminals and particularly to contact-terminals adapted for useon multiple contact electrical apparatus such as dial switches, rheostat's, and the' like. g a 1 The object ofthe invention is. the provision of an improved contact terminal which may be economically manufactured andwhich may be secured to a mounting plate without the use of additional parts such as screwsorrivets. I A further object is the provision'on such a'i terminaliof suitable means for supporting,

conductors' or resistance element's.

, In accordance with the above objects, the

preferred formof the invention comprises; a flat, punched metal contact termmal,

ada ted to be mounted edgcw'ise, provided wit a pair of integrallugs whereby itrmay be secured to a mounting plate, .-and a hopk-. shaped end may be readi y secured.

The invention will be" better understood j from a detailed description with reference to the accompanying drawing, in which Fig.

1 is a perspective view of a dialswitch, and Fig.2 is a perspective view of a contact terminal in accordance with the present invention.

In Fig. 1 the terminals 1 areshown arranged'in a circular row mounted on a plate of insulating material2. ,A movable conj tact 3 is attached 5 to a handle. 4 by which it may be rotated to wipe over the contact. terminals. m' v As shown in Fig. 2, the contact terminal comprises a main ody portion 1 havir ig a contacting surface 1" on "one edge. 3 W0 parallel lugs 1 and 1 extend from the edge of the main portion opposite the contacting surface 1 'A hook-shaped soldering terminal 1 is also provided whereby con'jducting wires may be attached as illustrated in will be seen from an examination of Fig. 1, the two, lugs 1 and 1 extend through said lugs w ortion to which aconductor said contact bein piece of thin flat metal, t us permitting a Q large number to be usedin' a relatively small space. Itrequires no bending operation and no screws or rivets to hold it in place.

' The appended claims are not to be construed aslimited to the specific showing as there are many, possible modifications of the i design which would co of the invention. I l

What is claimed is: 4 q

1.- In'combination, a perforated mountin 'plate, a metal contact, and a plurality o lugs projecting from said contact, said conme within the scope tact being secured to said plate solely by means of-one of said lugs whose end projects plate and is distorted.

.2. In combination, a perforated mounting plate, a metal contact, a soldering terminal,

and a plurality. of lugs projecting from said contact sai' d contact being secured to said mounting iilatelsolely by me'ans of one of torted.

ose end projects through a'perforat1on 1n sald mounting plate and is dis through a perforation in said mounting- 3. In combination, perforated mounting plate, *fitflitt punched metal contact, and a plurality of lugs" projecting fromone edge of sald. contact, said contact beingsecured to said plate solelyby means of. one of said lugs whose end projects through a perforatlon in said mounting plate and is d storted. 4. In combination, a perforated mounting plate, a flat punched "metal contact, a solder- 1 ng term 1nal',- and a plurality of lugs proectlngtrom one edge ofsaid contact, said contact being secured to said plate solely by means of one of said lugs whose end projects through a perforation in said mounting plate and is distorted.

5.. In a switching device, a perforated I mounting plate, a punched metal contact, a"

plur'ality of lugs integral with said contact, secured to said plate,

solely by meanso one of said lugs whose 7 end projectsthrough a perforation in said mounting plate and is distorted, and a soldering terminal integral with said contact and extending away from the, edge of said mounting plate. v

6. Inv combination, an insulating mounting plate having perforations, a plurality of flat metal contacts, each having lugs projecting from one edge for registering with said perforations, the edges of said contacts from which the ln 5 project forming a bearing surface for said. contacts, said contacts belng secured to said mounting plate solely by one of'said lugs whose end projects through said mounting plateand is upset.

7. In combination, an insulating mounting plate having perforations, a plurality of fiat metal contacts, each having lugs projecting from one edge for registering with mounting plate solel by one of said lugs whose end projects t rough said mounting plate and is upset.

8. In combination, an lnsulating mounting plate having rows of closely spaced perforations therein, 'a plurality of flat punched metal contacts, each having lugs projecting from one edge and registerin radially with said perforations, the edges 0? said contacts from which'the lugs project bearing upon said mountin plate, sa1d contacts being secured to sai mounting plate solely by one of said lugs whose end projects through said mounting plate and is upset;

In Witness whereof, I hereunto subscribe my name this 17th day of September A. D., 1921.

ARTHUR HADDOGKV
