Description

Nov. 7, 1961 J. o. ROESER TOGGLE SWITCH MECHANISM Filed Jan. 12, 1959 I NV EN TOR. Lfirzdiaaer Unite States Patent 3,008,024 TOGGLE SWITCH MECHANISM John O. Roeser, Park Ridge, Ill., assignor to Illinois Tool Works, Chicago, 111., a corporation of Illinois Filed Jan. 12, 1959, Ser. No. 786,114 7 Claims. (Cl. 200--172) This invention is concerned with an electric switch, and more particularly with an operating mechanism of a toggle switch.
Ordinary toggle switch mechanisms have a number of drawbacks. Such switches can be easily teased, with consequent arcing and erosion of the contacts. The mechanisms have a very short life and are frequently unreliable. Furthermore, conventional toggle switches lack the flexibility to be adapted to many different applications. Critical tolerances have generally been necessary.
Accordingly, it is an object of this invention to provide a toggle switch mechanism which overcomes the above enumerated difliculties.
More specifically, it is an object of this invention to provide a toggle switch mechanism made to ordinary production tolerances, most particularly, stamping tolerances.
Other and further objects and advantages of the present invention will be apparent from the following description when taken in connection with the accompanying drawings wherein:
FIG. 1 is a perspective view of a switch constructed accordance with the principles of this invention; FIG. 2 is a longitudinal sectional view through the switch as taken along the line 2--2 in FIG. 1 and showing the parts with the switch in on position;
FIG. 3 is a view similar to FIG. 2 showing the parts with the switch in off position; and
FIG. 4 is an exploded perspective view of certain of the switch operating parts.
Referring now in greater particularity to the drawings, there will be seen a switch designated generally by the numeral and including a substantially U-shaped sheet metal base 12. The base is provided at the bight thereof, illustrated at the top of the base, with a threaded bushing 14 for securing to a panel or the like in the usual manner. The bushing is provided with a partial transverse web 16 and a cross pin 18 pivotally mounting an operating member or handle 20 of the type known in the art as a bat handle. The handle at its lower, relatively small diameter end is provided with an axial bore 22 receiving the shank 24 of a headed pin 26 having a convex lower end or undersurface to the head 28. A coil spring 30 encircles the reduced lower end of the bat handle 20 and is compressed between the head 28 and a cylindrical enlargement 32 adjacent the pivot pin 18.
A suitable switch unit 34 of the low travel type is secured at the bottom of the base 12 between the sidewalls thereof by means such as bolts 36. The switch may be of a multiple type, having a plurality of plungers 38 disposed in parallel relation and aligned axially of the pivot pin 18. The switch is provided with terminal means, and in the illustrative embodiment there are two pairs of switch terminals 40 at each end of the switch, corresponding pairs being connected to switch contacts internally, operated by the respective plungers 38.
An operating member or lever 42 in the form of a flat blade or tongue is disposed within the base 12 above the switch unit 34 and is provided at one end with a pair of upstanding ears 44 by means of which it is pivoted on a pin 46 extending across the case in the direction of the pivot pin 18. The operating lever or tongue 42 is arranged to engage near its mid-section with 'ice all of the plungers 38 substantially on aline transverse of the axis of the lever or tongue. The blade, tongue or lever 42 angles up to the left in the switch off position of FIG. 3, and is substantially horizontal in the switch on position of FIG. 2.
A pivot pin 48 is disposed somewhat above the pivot pin 46, and on the center line of the switch 10 in alignment with the pivot pin 18 and the plungers 38. A rocking lever 50 is provided along the center of its longitudinal edges with depending ears 52 pivoted on the pin '48. The rocking lever 50, like the tongue 42 is a sheet metal stamping, and is somewhat wider than the lever 42, whereby the lever 42 may fit between the ears 52, the limit upper position of the lever 42 being determined by engagement with the pivot pin 48-. The tail of the rocking lever 50 is of reduced width as indicated at 42, for fitting between the cars 44, the limit clockwise position (in the drawings) being determined by engagement of the tail 54 of the lever 50 against the pivot pin 46, as in FIG. 3. At the opposite end, the rocking lever 50 is provided with a depending flange 56 which is engageable with the corresponding end of the lever 42. In the limit position, illustrated in FIG. 3, there is a slight clearance space 58 between the flange 56 and the end of the lever 42.
When the switch is in the OE position of FIG. 3, the spring 30 holds the pin head 28 against the rocking lever 50 to the right of the pivot 48, thereby holding the tail 54 down against the pin 46. The internal spring returns of the plungers 38 hold the plungers up against the lever 42, and hence hold the lever up against the pivot pin 48. As noted, the parts are so dimensioned that there is a slight gap between the flange 56 and the end of the lever 42. Thus, the length of the flange and of the other parts can vary somewhat in accordance with ordinary sheet metal stamping tolerances without affecting the parts as to the positions just described.
When the bat handle is pivoted in a clockwise direction (as viewed in the drawings) the head 28 of the pin 26 moves uphill along the rocking lever 50, compressing spring 30, until the head 28 passes a dead center position of the pivots 18 and 48. The rocking lever 50 then immediately starts to pivot in a counterclockwise direction, bringing the flange 56 into engagement with the end of the lever 42, and pivoting the lever 42 in a counterclockwise direction, all with a snap action, whereby to depress the plungers 38 with a snap action. The parts thus immediately move to the switch on position of FIG. 2. Switching in the opposite direction is precisely the reverse of the switching just described.
One advantage of the mechanism is that it makes it possible to obtain simultaneous action of the several switches within the unit 34. Thus, when the upward spring force of the first switch button to move is overcome by the lever 42, there is an immediate diminution of force upward on this lever, and the lever is moved even more rapidly by the spring 30, acting through the pin 26 and the rocking lever 50, whereby substantially instantaneously to depress the other plunger or plungers 38. Ideally, of course, the switches of the unit 34, including the plungers 38 thereof, would be identical. However, production tolerances are such that precise identity is not readily obtainable, and hence the action just described is most advantageous.
It will now be apparent that the spacing 58 between the flange 56 and the lever 42 is of considerable importance in allowing the use of ordinary sheet metal stamping standards. In practice, this gap is quite small, having been exaggerated somewhat in the drawings. In extreme cases, it may be substantially non-existent, whereas in extreme cases in the other direction it will still not be unduly large. The effective size of the gap is reduced relative to the plungers 38 by the lever action of the lever 42.
The specific example of the invention as heretofore shown and described is for illustrative purposes only. Various changes in structure will no doubt occur to those skilled in the art, and will be understood as forming a part of the invention insofar as they fall within the spirit and scope of the appended claims.
