To all whom it; may concern: 7

Be it known that I, FRANK E. SEELEY, a

i citizen of the United States of America, and

r'esidin "at Bridgeport, in the county of Fairfie d and State of Connecticut, have invented a certain new and Improved Pendent Electric Switch, of which the following is a specification.

' construction of pendent electric switch, more particularly of the single push button type.

. In the accompanying drawing, Figure 1 is a vertical section on the line 1-1, Fig. 3; Fig. 2 is a section on the line 2-2, Fig. 3; Fig. 3 is a section on the line 3-3, Fig. 1; Fig. 4 is a sectional view on the line 4M4, Fig. 3; and Fig. 5 is a perspective View of some details separated.

The body of the switch consists of a cup A of orcelain or other suitable insulatin material, with its open end downward, an its upper end closed except for certain holes formed for the passage of the terminal plates and the holes for the securing screws.

I the contact spring 10. are; arrang The moving parts of the switch mechanism are inclosed within this inverted cup andare wholly mounted upon a frame F, formed out of sheet metal stamped out and with certain parts bent into flan es. Thus there are two flanges f, f, threads to receive the threaded ends of securing screws 6, 6, assin through holes in the porcelain cup rom t e outside thereof. These screws are vthe means for firmly securing the switch frame and the movin parts thereon'to the insulating body A. T is frame F has a central extension 7, passing through a hole in the top of the cup body and rovided outside with a binding screw 8, t us constituting a terminal plate for one of the line wires.

On a flange 9 at the lower end of the frame plate is secured a bent spring contact '10, to bear against the ratchet contact wheel 0,? the making and breaking of the circu1 In.the present instance I have shown the switch as constructed for connection to three wires and so that the circuit maybe closed either through one pair of wires, all three wires or no circuit. Diametrically op osite' two actuating pawl plate 17 is a crank passin of t spring contacts 11 and 12 in the upper partof the cup, and connected with terminalri heral edges of four out of the sixteeth o the ratchet, as shown.

With this ratchet plate 'cooperates an actuating pawl plate 17, mounted to oscillate upon the center pin 20, and normally held up against the ratchet plate 16 on the wheel 0 by a spring washer 18. On the entering a cross slot Q1 in the push p ate P,

which is vertically guided partly by the center pin 20 passingithrough a vertical slot in the push plate (Fig. 4) and partly by the e lower stem of the push plate t-hroug a slot in the flange 9 of the'frame F. To the lower end of this push plate is secured a push button 1), and a spiral spring 22, interposed between the flange 9 of the frame and this button p, returns the push button and plate to the normal position shown in Figs. 1, 2 and 3, after each upward pressure, and with each such u ward ressure, the make and break whee O wil be turned to the extent of one tooth, as will be readily understood. By suitable changes in this ratchet wheel and spring contacts, varione make and break connections may be made. Iprovide a holea in the side of the inverted cup for inspection and adjustment of the upper contact springs.

By the described construction of endent switch havin an insulating body 0 1 an inverted cup s ape with the terminal plates passing throu h from the inside to the out- ,side .I provi ea strong switch with the mec anism well protected from the stray I strands of the connected wires.
