LIGHTED TOGGILE LEI/Elli SWIT CII BACKGROUND OF THE INVENTION Lighted toggle lever switches have been known heretofore. However, difficulties have been encountered in these prior switches in that the lamp bulb has been either not replaceable or very difficult to replace, requiring substantial disassembly of the switch. Also, such prior switches have used flexible leads or the like for commutating the current to the lamp in the pivoted handle, with their probability of failure due to repeated bending when the switch is used.
This invention relates to improvements in the lighted toggle lever switch art that overcome the aforementioned disadvantages.
SUMMARY OF THE INVENTION This invention relates to replaceable bulb lighted toggle lever switches.
An object of the invention is to provide an improved lighted toggle lever switch.
A more specific object of the invention is to provide improved means for mounting an indicator lamp within the han die of a toggle lever switch affording secure mounting and easy replacement ofthe lamp bulb.
Another specific object of the invention is to provide a lighted toggle lever switch with an improved snap-it handle on the toggle lever affording replacement of the lamp bulb mounted therewithin.
Another specific object of the invention is to provide a lighted toggle lever switch with improved electrical connector means for commutating current from the terminals in the switch base to the lamp bulb in the oscillatable handle.
Another specific object of the invention is to provide a lighted toggle lever switch with improved lamp connector means operating at the axis of rotation of the toggle lever to reduce wear.
Other objects and advantages of the invention will hereinafter appear.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. I, there is shown a switch according to the invention that may have, for example, a single-pole doublethrow switch action. This switch is provided with an insulating base 2 housing the switch contacts.
In the single pole double-throw version illustrated, two pairs of switch terminals A and s extend out through the bottom of the base for connection to an external circuit. These terminals are integral with or connected to stationary contacts within the base. The contacts of the two pairs thereof are alternately bridged by a movable bridging contact when the toggle lever is oscillated between its two operating positions. For example, the bridging contact may be a pivoted ll-shaped member operated through a compression spring from the toggle lever to provide snap-action closing or opening of the contacts. Switch contacts of this type are known in the art and reference may be had to A. W. Ifirieger U.S. Pat. No. 1,998,962, dated Apr. 23, 1935, for an illustration and description thereof.
As shown in FIG. l, the open top of the base is closed by an insulating cover 8 that is rigidly secured to the base by a pair of rivets ill or the like to provide a switch housing. integrally formed with the cover, an externally threaded bushing Ida extends up from the center thereof and is provided with a keyway 8b along one side thereof for nonrotatably holding a keyed washer when a nut is threaded thereon to mount the switch to a panel.
As shown in FIGS. 2 and 3, the inside of the bushing is provided with a suitable configuration for snap-in mounting of a toggle lever l2 and for pivotally retaining the toggle lever for movement in the plane of FIG. 3 without allowing it to wobble transverse from its proper plane of movement. For this purpose, the bushing has molded therein a socket be for the spherical portion 1211 of the toggle lever. The upper sides of this socket diverge to the top of the bushing to form a frustoconical opening t'ld through which the spherical portion of the toggle lever may be snapped into its pivotal seat. The lower portion of the bushing below the spherical socket is provided with a reduced opening be oblong in cross section to guide the lower end portion llZb of the toggle lever in the plane of its movement.
As shown in FIGS. 2 and 3, the reduced lower end portion 12b of the toggle lever extends part way down into the upper portion of the base and is adapted to engage the upper end of a toggle-action compression spring or the like for obtaining snap-action of the movable contact when the handle is actuated.
As shown in FIGS. 2, 3 and 5, toggle lever I2 has mounted thereon a snap-in transparent or translucent removable hollow handle M covering a lamp bulb to.
The upper end of this toggle lever I2 is provided with a lamp socket. For this purpose, this upper end is formed with a pair of spaced, flat upward projections 12d connected by a narrow web ll2e as best shown in FIG. 3 to provide a seat for the lamp bulb. A pair of small-diameter holes extend down through this upper end, one on each side of the narrow web, and terminate in lateral holes extending in opposite directions in spherical portion Illa on the axis of rotation thereof. A pair of small-diameter connector or conductor tubes Ill extend through the two small-diameter holes for receiving the two lamp bulb leads. A pair of resilient connectors such as helical compression springs 26) extend through the lateral holes and are compressed between conductor tubes III and lamp terminals 22, respectively.
As shown in FIGS. I and 2, bushing do is provided with two vertical openings tlf therethrough, one on each side, communicating with the lower and upper ends of the bushing and with the lateral holes in the spherical portion of the toggle lever. Thus, a pair of lamp terminals may be inserted up through the respective openings slightly past the lateral openings so that connector springs Ell bear thereagainst and electrically connect the lamp conductor tubes thereto. These lamp terminals are formed with an offset at about the midpoint as shown in FIGS. 2 and ii so that they extend laterally out between cover ii and the upper edges of the base. These lamp terminals or tend down in spaced-apart relation to the walls of the base so that suitable complementary terminals can be secured thereon.
The transparent removable handie is provided with a snapin connection to the toggle lever as shown in FIGS. 3 and l. For this purpose, the lower end of the handle is provided with a gripper l la consisting of a round hole connected by a slightly narrower slot to the lower edge of the handle. The toggle lever is provided with a round bead about the size of the hole in the handle. As will be apparent, when the handle is pressed onto the toggle lever, the sides of the slot will spread to allow the bead to snap into the hole to retain the handle on the toggle lever.
From the foregoing, it will be apparent that the switch may be readily assembled. To this end, connector springs 26) are first inserted into the lateral holes in the toggle lever and held in compression clear of the bushing walls by a suitable tool or jig while the toggle lever is forced down into the bushing. The lamp terminals are then inserted into their openings from below while the connector springs are held compressed. The compression tool may then be extracted to allow the connector springs to expand against lamp terminals 22 thereby to connect lamp socket tubes 18 to the lamp terminals.
The lamp bulb leads may be inserted down into the upper ends of socket tubes 18 whereafter handle 14 is pushed onto the toggle lever over the lamp bulb and snapped into secure connection. This may be done either before or after the toggle lever is assembled in the bushing While socket tubes 18 have been illustrated as tubular in form, it will be apparent that they could be split tubes or closely wound helical springs or the like. The electric current commutation means is subjected to minimum wear by using compression springs as connectors and placing these springs on the axis of rotation of the toggle lever where the motion is the least. The lamp bulb is arranged to fit snugly within the hole in the handle to minimize shock and bounce of the filaments therein when the switch is operated.
While the structures hereinbefore described are effectively adapted to fulfill the objects stated, it is to be understood that the invention is not intended to be confined to the particular preferred embodiment of lighted toggle lever switch disclosed, inasmuch as it is susceptible of various modifications without departing from the scope of the appended claims.
