13 Claims. 1
This invention relates generally to multiple position switch structures, particularly suited for use with an automotive vehicle as a combined starter and ignition switch and more particularly relates to improvements in such a structure wherein improved positioning means are provided to control the relative angular alignment be-- tween adjacent rotatable parts of the switch structure and wherein continuous biasing means are incorporated within the switch structure to insure a tight assembly of the assembled components.
According to the general principles of the present invention, an open ended housing having a key-lock in one end thereof encloses a rotatable carrier assembly having a driven connection with the keylock. The housing is provided with a, wall portion adjacent the carrier assembly formed with a plurality of depressions and a plurality of spring biased balls are received in the depressions to angularly position the carrier assembly relative to the housing. The bottoms of the depressions are tapered to provide inclined raceways for the spring biased balls, thereby tending to rotatably drive the carrier as! sembly toward a predetermined angularly aligned position. A base assembly is providedv in the other end of the housing and includes a pivot pin structure extending into the journaling the carrier assembly for rotation: in the housing. The pivot pin structure includes continuous biasing means engaging the keylock' to minimize rattling of the keylock in the housing.
It is an object of the present invention to provide a multiple position switch structure having improved means for angularly aligning relatively rotatable adjacent parts.
Another object of the present invention is to provide a switch structure having a rotatable, carrier assembly journaled on a pivot pin struc-t ture which is provided to align the rotatable components of the switch structure and to cons tinuously bias a key actuating mechanism axial- 1y spaced from the rotatable carrier assembly; thereby to minimize rattling of the switch struc ture components.
Another obiect of the present invention is to improve the positioning feel a manually op erated key actuated combination ignition starter switch.
h u in a d tional objects of the present invention will become manifest to those versed in the art upon making reference tov the detailed description which follows and the accompanying sheets of drawingsv in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative ex mple.

as shown on the drawings:
A combination igmtion starter switch structure asiiidi'cated generally by the reference num'eral IE and comprises a substantially cylindrical housing ll having a reduced diameter portion I2 at one end bounded by a medial radially extending wall H.
A keylock indicated generally at [4 i situated in the" reduced; diameter portion l2 and comprises a lock cylinder It having the usual lock tumblers therein which cooperatewith a key rotated shaft extending through the lock cylinder l6 and projecting into the housing A spring biased pin I8 is carried by the lock cylinder and is received by a slot |9 formed in the reduced diameter portion to prevent axial withdrawal of the keylock H from the housing A contact carrier assembly indicated generally at is situated within the housing l| adjacent the wall I3.
A base assembly indicated at 2| closes the large end of the housing I and may be secured in firm assembly therewith by peening over an edge portion 22 so as to securely stake the housing II to the base assembly 2|. It will be noted that the base assembly 2| includes an outer base 23 and an inner base 24, there being provided aligned contact means 26 in the inner base 24 which are electrically connected to appropriate binding posts 21 which extend outwardly through the outer base 23. A cable 28 is also provided and includes suitable conductor means 29 to establish electrical communication with the appropriate conductors of an electrical circuit to be controlled by the switching mechanism, for example, the ignition, starter and accessory circuits of an automotive vehicle which are to be controlled by the combination ignition-starter switch ID.
A pivot pin assembly indicated at 30 is secured in firm assembly to the inner base 24 and pro jects axially from one face of the inner base 24 into the housing thereby to journal the rotatable carrier assembly 36 and to radially align the carrier assembly 26 relative to the housing The pivot pin assembly 36 includes a pivot pin 3| having an annular shoulder 32 abutting one face of the inner base 24 and being peened over as at 33 to place the pivot pin 3| in firm assembly with the inner base 24.
The pivot pin 3| further includes a hollow tubular portion 34 housing a compression spring 36 which bottoms against a medial shoulder 31 formed on a lockpin 38 which is axially reciprocable within the tubular portion 34 and which projects outwardly from one end of the pivot pin 3| to resiliently engage the shaft ll of the keylock l4.
It will be appreciated that the lockpin 38 not only serves to properly align the components of the switch structure In by seating in the end of the shaft H, but also transmits the continuous biasing force exerted by the compression spring 36 to the keylock l4, thereby tending to minimize rattling of the keylock cylinder l6 in the housing Referring now more particularly to Figures 3 and 7 in connection with Figure 2, it will be noted that the contact carrier assembly 26 comprises a carrier 39 having a plurality of recesses 40 in one face thereof which receive a corresponding plurality of compression springs 4| arranged to resiliently bias a contact plate 42 toward the base assembly 2|. The Contact plate 4| is provided with a plurality of suitably spaced apart embossments 43 which establish point contact with the contact means 26 carried by the inner base 24 and thereby serving to selectively bridge suitable circuits associated with the contact means 26.
A cup-shaped spring housing 44 surrounds the carrier 39 and is securely assembled therewith by means of a plurality of bent-over lugs 46 matingly seated within a correspoiding plurality of recesses 41 formed in one face of the carrier 39 and a plurality of bent-over lugs 48 which are 4 matingly seated in a corresponding plurality of recesses 49 formed in the other face of the carrier 39.
A torque spring 50 is enclosed by the spring housing 44 and has one end retained by the carrier 39, a recess 5| being provided to receive a tongue 52 on one end of the torque spring 56. The other end of the torque spring 50 extends radially outwardly as at 53 and is received in slot 54 formed in the peripheral portion of the spring housing 44. It will be noted that the spring housing 44 is further provided with a radially outwardly extending lug 56 which lies in spaced alignment relative to the outwardly projecting end portion 52 of the torque spring 50. The torque spring 50 is initially loaded so as to have the end portion 53 seated in one end of the slot 54 and the ing 56 is preferably located adjacent the other end of the slot 54 for a purpose which will become manifest presently.
The bore of the generally cylindrical housing r is provided with a relieved arcuate recess 51 extending between a pair of radially spaced shoulders 58 and 59. The carrier 39 is provided with a centrally disposed aperture 60 which receives the tubular portion 34 of the pivot pin 3|. Thus, the pivot pin assembly 30 serves to journal and support the contact carrier assembly 23 for rotation in the housing and also radially aligns the carrier contact assembly or switch assembly 20 so that the end portion 53 of the torque spring 50 and the lug 56 of the spring housing 44 extend into the arcuate recess 51. It will be readily evident that the lug 56 serves to limit the angular displacement of the contact carrier assembly 26 relative to the housing I by engaging the shoulders 58 and 59.
Referring now more particularly to Figures 5 and 6, it will be noted that the wall |3 is provided with a plurality of circumferentially aligned depressions forming alternately spaced ball seating recesses 62 and elongated guiding recesses 63.
The profile configuration of the recesses 62 and 63 is clearly shown in the developed diagrammatic view of Figure 6.
It will be noted that each of the ball seating recesses 62 is provided with a substantially symmetrical indented portion bounded on either side by a shoulder portion tending to restrain a shiftable element such as a ball against relative displacement.
The elongated recesses 63, on the other hand, are provided with tapered bottoms, thereby to provide a relatively deep end portion 63a and a shallow end portion 63b and further providing an inclined raceway 63c between the end portions upon which the shiftable element such as a ball may be moved.
To cooperate with the recesses 62 and 63 formed in the wall l3, there is provided a plurality of recesses 64 in the carrier 39, each recess 64 bottoming a coiled compression spring 66 which is axially aligned between the carrier 39 and the wall I3. A shiftable element such as a ball 67 engages each spring 66 and is arranged to cooperate with a corresponding pair of the recesses indicated at 62 and 63.
The recesses 62 are arranged to normally align the carrier assembly in a predetermined position within the housing corresponding to a first position, or an off position. The off position is indicated in the drawings by the broken line showing of the balls 61 seated in the recesses 62, a corresponding broken line showing of the contact plate 42 being indicated on Figure 4 at 420.
The carrier 39 is provided with a Suitable driving connection indicated at 68 with the shaft ll of the keylock I4 so that selective angular displacement of the rotatable contact carrier assembly may be effected upon rotation of the shaft I! in the lock cylinder I6.
Upon rotative displacement of the carrier contact assembly 29, the balls 61 will be moved into the deep end portion 63a of the elongated recesses 63, which position corresponds to an ignition on position, or a second position. The ignition on position corresponds to the full line position of the balls 6'! in Figure 6 and in Figure 4 the contact plate 42 is also shown in full line with the embossments d3 eifecting an appropriate bridging action across the terminals of the contact means 26 in control of the so-called ammeter circuit conventionally provided in an automotive vehicle.
In the second position, the end portion 53 of the torque spring 59 will be aligned in engaging abutment with the shoulder 58. Upon eliecting additional angular displacement of the contact carrier assembly 2% by rotating the carrier assembly beyond the ignition on or second position, the balls 6i! will be moved upwardly on the inclined raceway $30 of the elongated recesses 63 to a starter position, or a third position shown by the dotted line balls of Figure 6 and the dotted line position of the contact plate 42 shown in Figure 4 at 328.
It will be appreciated that the movement of the contact carrier assembly between the ignition on position to the starter position will be resiliently impeded by the torque spring because of the engagement of the end 53 of the torque spring fit with the shoulder 58. In this regard, it may be noted that the spacing dimension between the end portion 53 of the torque spring 59 and the lug 56 on the spring housing 44 is approximately coextensive with the length of the elongated recesses 63. Thus, as soon as the keylock M is released by the operator, the torque spring will rotatively drive the carrier contact assembly back to the ignition on position.
To further improve the positioning feel of the manually operable combination ignition-starter switch It and to provide an improved actuating mechanism between the relatively rotatable parts of the switching mechanism, the present invention contemplates the development of an additional driving force which will return the contact carrier assembly 20 to the ignition on position after release of the manually operated ignition lock It.
It will be noted that the movement of the balls 67 from the deep portion 53a of the elongated recesses 53 to the shallow portion 63b results in a compression of the springs 66. Upon release of the keylock I4, the balls 51, together with the recesses 63 will act to rotatably drive the contact carrier assembly 20 to the ignition on position.
Although various structural modifications might be suggested by those versed in the art in connection with the preferred structural embodiment disclosed and described by way of illustrative example, it should be clearly understood that I wish to embody within the scope of this inventionall such modifications as reasonably and properly come within the scope of my con tribution to the art.
