Fig. 5 is a view taken substantially along the line 5--5 of Fig. 2;

Fig. 6 is a developed view of the bulb retainer; and

Fig. 7 is a view similar to Fig. 2 showing a modilied form of the invention.

Referring to the drawings, the numeral l indicates generally the instrument panel of a motor vehicle having a glove compartment 2 adapted to be closed by means of a door 5. As is normal in most glove compartments, there is provided rearwardly of the door an end frame 6 having a gusset 8. The light-switch combination it is received within an aperture 12 in the gusset 8.

The light-switch combination comprises a tubular housing M which may be. and preferably is of insulating material such as molded phenolic; Internally, the tubular member it comprises concentric cylindrical sections Hi, i! and [8 of progressively reduced diameter which provide at their intersections shoulders 19 and 2B.

A current conducting tubular element 22 is positioned within section is of the tubular member M and has an out-turned flange 23 seating against the shoulder 21%. The other end portion of the element 22 extends outwardly of the end face 24 of the tubular member Hi and through a central aperture in a snap fastener button 26. The outer end portion of the element 22 is spun outwardly to lock the flange 23 against the shoulder and the button 26 againstthe end face 24 of the housing !4. The button 26 is provided with a plurality of peripherally spaced resilient fingers 32 which project generally in a direction toward the other end 34 of the tubular member l4 and serve to provide a resilient snap secure ment for releasably holding the combination it within the aperture 12.

The operation of the lamp 35 is controlled by a post 36 having an enlarged head 37 positioned within the cylindrical portion ll adjacent the shoulder 26. The post 35 further has a stem 38 which extends outwardly'through the element 22 externally of the housing It whereby it may be operated externally of the housing, as for example, by the glove compartment door t.

An annular current conducting contact member 39 fits over a cylindrical projection ill at the inner end of post 35. One peripheral edge portion of the head 31 is cut away as at ll to permit a tab 42 of the contact 39 to extend along the head 3?. When the post 33is in its leftward, or switch-closed position, as shown, tab .12 engages the flange 23 of the tubular element to permit current flow therebetween, and provide a grounding connection through button 23, and frame 6.

The contact 39 is electrically connected to the central terminal id of a bulb receiving socket 46 by means of an electrically conducting spring 48, which has one end portion fitting over the projection 46 and engaging the contact 39. The expansive force exerted by the spring 63 acts to securely hold the contact 33 against the head 3i of the post 36, and to urge the post 36 into its circuit closing position, in which the tab 42 engages the tubular element 22.

The terminal t l is carried within a central aperture of amovable insulating disk 5%, and is provided with a cup-shaped projection 55 which extends toward the post 35 and. cages the adjacent end portion of the spring The disk 50 is slidably received within a sleeve 52 mounted within the section 5 8 of the tubular member ad jacent the end 34 as by a press fit. A plurality of fingers 54 are bent inwardly from the sleeve 52 to provide stops for limiting the outward movement of the disk 50 whereby the spring 418 is always maintained under stress.

The sleeve 52 is provided with diametrically arranged J-slots 56 for cooperation with diametrically extending prongs 58 of a li ht bulb or lamp 35. The slots are positioned relative to the fingers 5 so that when a lamp 35 is in place the lamp maintains the disk 50 away from the fingers 54, permitting the sprin 48 to hold the terminal 44 tightly against the cooperating terminal of the lamp 35. The parts are shown with the bulb only partially inserted. The final inserting movement, of course, seats the prongs 58 in the J-slots, and spaces the disk 58 away from the fingers E i, as aforesaid.

The sleeve 52 is provided with an outwardly extending rebent tang (it for connection with an electrical supply conductor 52. The tang 6'1; and conductor 52 are accommodated in a recess in the wall of the tubular member i l.

Referring more specifically to Fig. 6, the sleeve 52 may be made from a substantially planar sheet of metal which is apertured as by a punch press operation to provide the J-shaped slots 5% opening outwardly through one side wall thereof. As shown the left-hand lower corner of the sheet is notched out to the depth at which the fingers 54 are to be located leaving a small projection E la which will later be bent to provide one of the fingers 54. As shown two fingers 5 2- are provided which are arranged diametrically with respect to eac other and therefore the sheet is apertured as at 5d leaving a projecting metal piece 54b which will be bent in the same direction as the projection 5G0. to provide the other finger 54. In order to provide a snap entry of the sleeve 52 into the tube section 56, the sheet is provided with offset bumps 55. The tang 6% is provided by shearing the sheet along line a parallel to the edge through which the J slots open, and rebending the finger thus provided. The sheet is rolled into cylindical shape with the fingers extending radially inwardly the bumps t5 and tang 6U extending outwar- When the sleeve 52 is inserted into the slightly elastic housing i l, the bumps it behind shoulders 68c defined by recesses 88 in the walls of the section 96, and thus hold the sleeve 52 against undesired withdrawal.

As shown the conductor 52 forms one terminal of the combination id and the button 255 the other terminal, whereby when the button is inserted into the aperture in the metal gusset, it is connected with the grounded terminal of the motor vehicle battery (not shown). The conductor 62 is connected to an ungrounded portion of the vehicle battery. Thusly connected and with the door 4 open, an electrical circuit will be completed from the battery (not shown) through conductor 52, sleeve 52, lamp 35, terminal M, spring 48, contact 33, tab element 22, button and gusset 8 to the grounded side of the battery. Upon closure of the door t, the stem 33 is moved against the force or" the spring 68 to cause the tab 42 to move away from the element .22 and break the circuit through the combination, thereby extinguishing the lamp 35.

In the form shown in Fig. 7, the tubular element 22a is provided with a projection it which extends beyond the head 3'! and which electrically engages a projection 12 of the annular contact 39a. ihis projection is received within a longitudinally extending slot 13 in the wall of tubular section I! and is formed to provide adjacent its outward end a contact portion M which resiliently engages the outer surface of the cup-shaped portion it of the terminal carried by the disk 58. The sleeve 52a is similar to sleeve 52 but instead of being provided with fingers 54 is provided with inwardly deformed side wall portions to provide stops 18 arranged at 120 intervals about the sleeve to limit the movement of the disk 50 by the spring 48. With the switch elemant 36a in the position shown, the

portions

10 and 12 are in electrical connection to complete a circuit from the conductor 62, sleeve 52c, lamp 35, terminal 44a, portion 16, portion "i l, projections 72 and iii, element 22 to button 26. Upon closure of the door 4, the switch element 36a is moved against the face of the spring 48 to move the portion (2 beyond the end. of portion it to break the circuit through the combination lea.
