ABSTRACT OF THE INVENTION
A switch for controlling the current to a load combining an ON-Off switch in series with a variable resistor. Switch has a housing which includes an actuator guided along a dimension of the housing.

Description
?$
BACKGROUND OF THE INVENTION
The present invention relates to a novel switch device whieh may be used to eontrol an ON-OFF switeh as well as a voltage regulating switeh.
The standard dimmer switch for an eleetri-eal light has ineluded a rotary element useable in conjunction with a push or pull meehanism. The rotary element generally eontrols the dimming of the lamp while the push-pull mechanism turns the lamp to either the on or off position.
A later development found in the United States Patent 3,746,923, deseribe a dimmer having a linear eontrol. The linear eontrol permitted the user to more easily control the lighting, in that full range of lighting levels may be attained by simple up or down motion. In addition, the on-off funetion was intergrated into the path of the travel of the linear element.
The combination of the linear ~;mm;ng funetion and the on-off function ln a single control, although satisfactory for a eompact relatively low power rated di~mmer, is not applicable where these functions must be separated~ A eontrol switch which ~$
permits the separation of the on-off function from the voltage regulating portion of the switch yet maintains the proximity of these two elements in a single unit would be an advance in the electrical art.
~q3~
SUMMARY OF THE INVENTION
In accordance with the present invention a novel switch for controlling the current to a load which combines an on-off switch in series with a variable resistor is providedO
The switeh of the present invention includes a housing which has a guide along a dimension there-of. The guide may take the form of a groove or series of grooves whieh extend along a dimension of the housing.
An actuator is also provided in the pre-sent invention. The actuator moves along the dimension of the housing which generally coincides with the dimension of the guide wi-thin the housing.
The actuator further ineludes an opening there-through for permitting a portion of the variable resistor to pass therethrough. This opening may be an elongated opening to permit linear movement of the variable resistor. In addition, the aetuator may be constructed with a cam surface for contact-ing a portion of the on-off switch which results in operation of the same.
~.
A cover may enclose the actuator in re-lation to the housing. The cover also has an opening therethrough to pexmit movement of the portion of the variable resistor which also passes through the actuator opening. In addition a slider may be connected to this portion of the variable resistor and be movable in relation to the cover. The user gains access to the slider on the exterior of the cover for facilitating the working of the switch.
The switch of the present invention also includes means for transmitting light along the dimension of the actuator. Source of light positions adjacent the actuator, preferably within the cavity in the actuator. Cavity would be formed to permit movement of the actuator without contacting the source of light. Moreover the actuator is formed to extend outside the cover enclosed housing -to permit the user to manipulate the same. The light transmitted along the dimension of the actuator would appear on this portion or leg extending ~eyond the confines of the cover.
It may be apparent that a novel and useful switch mechanism which is especially useful in regulating an incandescent lamp has been provided.
It is an object of the present invention to provide a switch for controlling the current to a load which has on-off switch and a variable resistor in series within a unit such that the switch devices are separately and easily operable b~ the user.
It is another object of the present inven-tion to provide a switch for controlling the current to a load which i.ncludes an on-off switch which has a leg that is lighted from within the main housing of the switch unit.
It is another object of the present in-vention to provide a switch for controlling the current to a load which is capable of handling larger elec-trical power than prior switches.
It is another ob~ect of the present invention to provlde a switch for controlling the current to a load which is sepcially useful in controlling the on-off function as well as the d;m~;ng function of an incandescent lamp.
6~5 The invention may fully and correctly be described as a switch assembly fo. controlling the current to a load combining an on-off switch in series with a variable resistor. The assembly includes a housing having a guide for controlling the movement of an activator. The stop limits the movement of the actuator. The actuator includes an opening therethrough to permit the firsk portion of an element to extend through the actuator and permit the second portion of the element to remain on the other side of the actuator. The actuator further includes a cam surface to contact a portion of the on-off switch for operation of the same. The opening and stop are sized and positioned to permit the operation of the on-off switch.
The invention possesses other objects and advantages especially as concerns particular charac-teristics and features thereof which will become apparent as the specification continues.

D~SCRIPTION OF THE PREFERRED EMBODIMENTS
Various aspects of the present invention will evolve from the following detailed description of the preferred embodiments thereof which should be taken in conjunction with the hereinabove drawings.
The invention as a whole is represented in the drawings by reference character 10. The switch device 10 includes as one of its elements a housing 12, FIGS. 1 and 3. With reference to FIG. 3 it may be seen that housing 12 includes a front plate 14 and a back plate 16. Fins 18, 20, 22, and 24 are formed between front and back plates 14 and 16. Chimneys 26 and 28 between fins 18 and 20 and 22 and 24 respectively per~it the dissapation of heat from the switch device 10. Space 30 includes grooves 32 and 34 which serve as guides for a slider 36. Element 38 connected to slider 36 represents a portion of a variable resistor which generally serves as a dimmer for an incandescent lamp or other load (not shown). Element 38 moves generally in a linear manner, With reference to FIGo 1 it may be seen that slider 36 has a series of -tabs of legs 40 which fit within grooves 32 and 34O A
cover 42 having an opening 44 exposes a portion of slider 36 to the user. A knurled pedestal 46 permits fingertip control of slider 36~
Turning to FIG. 2, it should be noted that cover 42 has been removed from opening 30 revealing slider 36. Scored crevices 48 and 50, FIG. 2, as well as grooves 52 and 54 on plate 16, FIG. 3, permit the breaking off of a portion of housing 12 such that a plurality of such housing may be placed side by side to operate multiple switches. The "ganging" -technique is well known in the art.
~ n actuator 56, FIG. 2 and 3, but best shown in FIG. 4, is movable along space 30.
~ppendages 58, 60 and 62 and 64 slide in grooves 66 and 68, FIGS. 3 and 6. With reference to FIG.
4 it may be seen that actuator 56 includes two legs 70 and 72 which makes 10 beyond the lenc~th of housing 12 and cover 42 when it is in place.
Slots 74 and 76 include stops 78 and 80 which serve to limit the travel of the actuator 56 in its travel along grooves 66 and 68 i.e. the long dimension of housing 12. Slot 82 serves as an open~
ing through actuator 56 for linear element 380 It may be apparent that stops 78 and 80 also serve as rivets for any appurtenances which may attach to the back of plate 16. For example, in the element 38 and the potentiome-ter connected thereto (not shown). Slots 86 and 88 permit the connecting of device 10 to a wall box.
Actuator 56 also includes cam surface 90 for moving portion 92 of the on-off switch not shown. As may be seen from FIG. 5 cam surface includes two distinctive positions. These posl-tions coincide with the limit of travel of actuator 56 along slots 74 and 76.
Device 10 also embraees means 94 for transmitting light along the lengthwise dimension of actuator 56 i.e. from leg 70 to leg 72. Means 94 may take the form of constructing actuator 96 of material having internal reflectance. In light source 96, FIGS. 4 and 5, fits within a slot 98 such that the travel of actuator 56 will not cause any eontact with a light souree 96. Thus, with slider 36 and eover 42 in plaee, light 70 and 72 will appear illuminated. Thus slo-t 98, which does not extend through aetuator 56 serves as a eavity.
An operation, the device would be in the configuration shown in FIG. 1 where slider 36 and cover 42 are in placeO The two legs 70 and 72 of actuator 56 would appear illuminated by the action of means 94 in order that the user may find the same and a dark space. A push upwardly or downwardly on actuator 56 would operate on-off switeh 92 via the heretofore deseribed aetion of eam surfaee 90~ With the on-off switeh in the on posi-tion the user would then adjust the ll~ght level o~
the lamp (not shown) connected to device 10 by moving slider 36 upwardly or downwardly to the desired end point. Slider 36 would have caused the movement of linear element 38 along slot 82. Thus, the switch of the present invention accomodates an on-off switch as well as a variable resistor in the same unit.
While in the foregoing embodiments of the present invention have been set forth in considerable detail for the purposes of making a complete disclosure of the invention, it may be apparent to those of skill in the art that numerous changes may be made in such detail with-out departing from the spirit and principles of the invention.
