TOGGLE SWITCH.

A Animation med November 2o, 192,2'. seriarivl 602,083,

To t may concern: .Be it known that I, C E. Avnxr,

a citizen of the United States of America, and residing at East Orange, 1n the-county f of Essex and State of New Jersey, have'in-,

-vented -new and useful Improvements of which the following 1s a ecification.

y invention relates particularly to what are sometimes called toggle or tumbler switches, and part'cula'rly tothe actuating -mechanism.

, The main object is to provide a simple but reliable'mecha-nism whlch can be readily made and easily 'operated andwhich issmall and compact.

Another object'is to' tion which can be assem of rivets. u

` Another object is to provide a construe# tion, many of the arts of which can be' interchangeably use for either a toggle switcher a push button switch.

rovide a construeled without the use In its preferred form the invention coif'i' templates the .use of a pivoted contact carrier to 'which is loosel hinged a throwing link., The actuatori's or cross bar and serves' to hold the other parts in .place in the`receptacle. This actua0v ator. is of s uch a nature that it can be readily attached to the bridge, which is also ada ted tobe usedin a push button switch, toge her with the other parts df the structure.

, Fig. 11g-is an edge view of the saim'ashovv-v lstandar nged `to the bridgethe link 22, Vas shown inFig. 2. This rocker ing a section of the supporting bridge and r escutcheon plate.A The body or receptacle 12 may be formed of insulating material, such as porcelain or' molded composit onand contains the necessary stationary contact or contacts of suitable form suitably secured in place. 'j The movable 'r swinging switch member 13'is suitably'sec red to a carrier 14, which 'has pro'ectingbenrings 15 hung in the side s 16, which project 'from one end 65 o f the frame 17. This 'carrier is of U-sha e' and its bottom bar 18 swin between lthe standards `16 and the shoul ers ,19, which* serve as stops to limitthe throw of the car rier and movable switch member.

The frame 17 may be conveniently positioned within the receptacle,- for instance, means of the lugs such as 20 and-21 properly locatedl with respect .to the projec-V tions and recesses -within the rece tecla., The construction is such, however, t at'as will be hereinafter understood, no 'attaching screws are required for holding the frame in place.

Hinged loosely to the cross bar 18 is a: link 22', which' carries the spring 23. -This spring is. held in place on the link by a washer 24:, and the link is provided with lugs 25, which serve as stops #for the washer 24.- This washer 24 may also have one or more side. flanges 26 adapted-to en- .85 gage the edges of the cross bar 18, when the spring is fully compressed. f

Il-he actuating device consists of a lever or handle 27, and a rocker 28 suitably secured together as, for Ainst-ance, by the rivet heads 29. The rocker is providedwith outwardly projecting pivot pins 30 supported in lugsv 31 at the sides of the bridge 32. The brid e is slotted centrally at'33 and provided wi openings 33 The lever 27 cxtends through the slot 33 and the shoulders 34 on the rocker serve as stops which engage the lower face-of the bridge-as the actuator is swungfrom sideto side. The tip 35 of the actuating rocker preferably'rather sharp and adapted'to engage the washer btween the arms'of is also provided with a slot 36 to allow for means of the usual screws 3T.

'the movementof the arms of the link, as the actuator is swinging back and forth.

The bridge 32 is adapted to be suitahl)1 secured to the top of the receptacle' 12 in any suitable mnner,'as',for instance, by A. face plate, such as 38 is adapted to he secured iu the usual manner to the bridge, for instance. by means of one or more screws 130. In order to fill the central opening in the tace plate and provides finish forY the interior parts at the junction ot' the operating lever 27 and the bridge I l'irovif'lean eseutcheon place in the frame 17 aridthe frame in place in thereceptacle 12, without the need of any attaching screws, thus doing away with .l the necessity of sciews ordinarily employed for such purpose. The carrler and frame are so constructed that they can he readily assembled witholrtthe'nse of tools. Since no rivets or pins 'fare required, when the actuating lever. 2? s tilted, the rocker, of

` tact member` `the opposite tposition,analiv ing or breakmgthe circuit `as the lca'seimay" course, moves with i t and compresses the 'spring until the line o fcenters ls'passed,4v

whereupon tb `spring snaps the-switch' conbe. In cese the switch contacts should-stick, however, the flunge 26 of the washer 24 will be forced :igttinst the opposite Mge of the carrier'hnr 1S, after -the lugr passes beyond the center line and thus power will be directly applied from the hund through the rocker to start the movmncnt of the carrier, which once started will be completed by the kick ol the spring.

The rocker may be formed und connected to` the bridge h v bending over the ears or lugs 31. or thcl bridge cnrs muy be bent over and the rocker pins inserted h v spring# Y' ing the sides of the bridge apart. Sin'iilarly the rocker may he detached from the bridge and another bridge andpush button substituted, if desired.

Other forms ot :Yet-Hating levers and rockers may be employed. as indicated.' for instance` in Figs. 10 :and ll. where l have shown the rocker laying side plates 43 con? nected by the tip 44. In this case the side plates have outwardly extending pivot pins l 45 adapted tobe supported in the bridge.

' The lever 36 may be suitably secured to the rocker. for instance` byrivets 47 and 48. Other changes may be made in the' details of construction within the scope of my invention. f Y
