Mallory & Co. Inc, Indianapolis, End, a corporation of Delaware Filed Oct. 6, i966, Ser. No. 534,768 8 Elairns. ((11. 2130-172) ABSTRAET OF THE DISCLOSURE An adapter for a switch which provides selective operating conditions for the switch.
This invention relates to snap action mechanisms, and particularly to an adapter for snap switches.
Snap action mechanisms have found great utility in recent years since they are relatively simple and economical to actuate the mechanisms with which they are associated with a positive stroke of the snap blade even though the force which acts to actuate the mechanisms is applied very slowly. More particularly such snap action mechanisms have found particular utility in the electrical field in the form of snap and/ or double throw snap action switches since the quick snapping action of the snap blade associated with the mechanism is effective to substantially eliminate arcing between two adjacent contacts.
In switches such as these, adapters are usually required so that the switch may be readily actuated in accordance with predetermined requirements. The present invention provides for such an adapter and has as one of its foremost objects the provision of means to provide either a momentary electrical impulse or a permanent electrical contact.
Another object of the invention is to provide such an adapter which is small and compact.
Another object of the invention is to provide such an adapter which is easily aligned with the switch.
Yet another object of the invention is to provide such an adapter wherein a single actuator bar actuates the switch button.
Another object of the invention is to provide such an adapter which utilizes a return spring to bias the actuator bar.
Still another object of the invention is to provide such an adapter wherein the actuator bar and the return spring are disposed within a two piece cover and wherein the pieces are held together by staking thus, rendering the adapter susceptible to a plurality assembly.
With the above and other objects in view, which will appear as the description proceeds, this invention resides in a novel construction combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the invention here disclosed may be made as come within the scope of the claims.
In the accompanying drawings:
FIGURE 1 is a perspective view of a bank of the adapters attached to and made part of a corresponding bank of switches;
FIGURE 2 is an exploded view of the novel adapter showing its relationship with a switch;
FIGURES 3 and 4 are side views of the adapters taken along the line 33 of FIGURE 1, with portions of the adapter being in cross-section; and
FIGURE 5 is a section taken along line 55 of FIG- URE 3.
Generally speaking, the objects of the invention are accomplished by providing an adapter for a switch, which in the main, comprises spring biased actuating means adapted to selectively engage the actuating means of a snap switch. More particularly, the adapter comprises a spring biased actuator bar having a cam surface adapted to engage a snap switch button having a cam follower surface such that when a selective external force is applied to the actuator bar the switch button is correspondingly selectively actuated. Such selective actuation of the actuator bar permits either a momentary electrical impulse or a permanent electrical contact.
In its perferred construction as shown by the drawings, the adapter comprises a cover preferably constructed in two identical sections, the cover being adapted to be fastened to a snap switch. The snap switch has a switch button extending through the housing of the snap switch through an aperture formed in the housing. The button has a cam follower surface on the end extending from the housing. Each of the sections forming the adapters cover have notches centrally formed in their abutting edges to form an opening in the cover. An actuator bar comprising a knob, a shank portion connecting the knob to a base, and a cam extending from the opposite surface of the base, extends through the opening in the cover, with the base being held in bearing relationship with the underneath side of the cover by a return spring disposed over the switch button of the snap switch. The return spring has a slot through which the cam of the actuator bar extends so as to be in actuating relationship with the cam follower surface of the switch button. To operate the snap switch for a momentary electrical impulse the actuator bar is pushed in causing the cam of the actuator bar to depress the switch button. For a permanent electrical contact, the bar is pushed forward causing the button switch to be permanently depressed through the movement of the cam against the cam follower surface of the button.
The sections of the cover are joined together through staking such that a bank of adapters can be readily adapted to a corresponding bank of switches.
Referring now to FIGURE 1, there is shown a bank of the novel adapters 10 attached to a corresponding bank of snap switches 11 by means hereinafter described. Each of the adapters has a cover 12. which, for each of assembly, is composed of two identical sections 13 and 14. The separate adapters are staked together through dowel pins 15.
Referring to FIGURE 2, a typical snap switch 11, for which the novel adapter is suitable, is composed of a housing 16 which is preferably, for ease of assembly, divided into two sections 17 and 18. A switch button 19 having a cam follower surface 20 extends through aperture 21 of the housing 16. Electric terminal leads 22 also extend from the housing and are in electrical contact with suitable switching blades located within the housing. Switch button 19 is also connected to such switching blades. Both the housing 15 and the switch button are fabricated from an electrical insulating material such as a thermosetting resin plastic, for example, as is the cover 12 of the adapter.
As previously stated, the cover 12 for the adapter is composed of two identical sections 13 and 14. The two sections are attached to section 13 of switch cover 16 through the pins 23 onto which slots 24 and 25 and their counterparts of section 13 are mated. Pins 23 have a flanged top portion 23a such that the sections 13 and 14 can be securely held to the switch housing. The sections of the cover are staked together in a manner more clearly shown in FIGURE 5.
Referring to FIGURE 5, section 13 has a bore 13a into which extension 14a of section 14 is received with a snug fit. Additionally bore 13a has a charnfer 13b such that the ends 141) of the extension can be flared upon i the application of heat. Section 14 also has a bore 14b through which the dowel pins 15 are passed.
Returning to FIGURE 2, the abutting edges 26 and 27 of sections 13 and 14 respectively have notches 28 and 29 cut in them in spaced relation such that opening 31) (FIGURE 1) is formed in cover 12 of the adapter. Actuator bar 31 which actuates the switch button 19 extends through this opening.
Actuator bar is made up of three sections: a base 32, a shank portion 33 connecting the base 32 to knob 34, and cam 35 extending from the opposite surface of the base. The bar may be of a one piece construction, and is fabricated from an electrical insulating material such as that used for the cover of the adapter and the housing for the switch. The actuator bar is carried by a return spring 36 having a slot 37 through which cam 35 extends. The return spring is positioned over switch button 19 such that cam 35 can be engaged with the cam follower surface 20 of button 19. This can be more readily seen with reference to FIGURES 3 and 4.
Referring to FIGURES 3 and 4, the actuator bar is carried by the return spring 36, the spring being biased such that when the spring is in its relaxed position the base 32 is held against the inner or underneath surface 38 of the adapter cover 12. The spring slidably rests on the surface 39 of switch housing section 13 such that cam 35 is substantially in alignment with switch button 19 such that the cam can readily be engaged with the cam follower surface 20.
In operation and with specific reference to FIGURE 3, a permanent electrical contact is made in the switch '11 by pushing knob 34 in the direction of the arrow. This moves cam 35 over cam follower surface 20 to the position 40. Likewise, return spring 36 assumes a new position 41. Thus, the switch button is depressed to position 42, and since the cam 35 is positioned over the button 19 as shown, a permanent electrical contact is made in the switch. That is, the contact is permanent until the knob 34 is pushed back to its original position.
Referring to FIGURE 4, when knob 34 is depressed in the direction of the arrow, the actuator bar is pivoted against point P where the base 32 bears against the inner surface 38 of cover 12. As cover 35 moves over cam follower surface 20 of button 19, the button is depressed. When the knob is released, return spring 36 moves the actuator bar back to its original position. Thus, a momentary electrical impulse is achieved.
From the foregoing description, taken in conjunction with the accompanying figures of the drawing, it will be readily apparent to those skilled in the art that this invention provides a new and improved adapter for snap switches, the principles of which may be applied to other similar devices.
