Meyer, Tecumseh, Ontario, Canada, and Nicholas Tornk, Melvindale, MiclL, assignors to General Motors Corporation, Detroit, Mich, a corporation of Delaware Filed Apr. 6, 1960, Ser. No. 20,286 6 Claims. (Cl. 200-6) This invention relates to circuit controllers that have particular utility in controlling an electric driven seat adjusting mechanism for a motor vehicle.

One of the objects of this invention is to provide a circuit controller that is adapted to control a plurality of circuits by use of a minimum number of parts and a single actuator that is shiftable in two planes.

Another object of this invention is to provide a circuit controller having a manually shiftable actuator that is movable in two planes, the switch including contactors adapted to complete two circuits when the actuator is shifted to either of two positions in each of its planes of movement.

A more specific object of this invention is to provide a circuit controller having an actuator which is shiftable in two planes and which'moves contacts carried by spring arms into engagement with fixed contacts carried by an insulating base, the insulating base carrying a pair of strap connectors each having spring fingers which are alternately engaged by the movable contacts as the actuator is shifted in a given plane.

Further objects and advantages of the present invention will'be apparent from the following description, reference being bad to the accompanying drawings wherein preferred embodiments of the present invention are clearly shown.

In the drawings:

FIGURE 1 is a lower plan view of a circuit controller made in accordance with this invention.

FIGURE 2 is a sectional view taken along line 2-2 of FIGURE 1.

FIGURE 3 is a plan view of an assembly forming a component part of the circuit controller of this invention.

FiGURE 4 is a sectional view taken along line '4-4 of FIGURE 3.

FIGURE 5 is a sectional view taken along line 5-5 of FIGURE 3. .1

FIGURE 6 is a sectional view taken along line 6-6 of FIGURE 3.

FIGURE 7 is a plan view of a strap connector which forms a component part of the circuit controller of this invention.

Referring now to the drawings and more particularly to FIGURE 2, it is seen that the circuit controller of this invention includes a housing designated by reference numeral 10. The housing 10 carries an assembly which is designated in its entirety by reference numeral 12, the assembly 12 being secured to the housing 10 by means of spring clips 14. The assembly 12 includes a base member 16 which is formed of insulating material and which has an integrally formed central projection 18. The insulating base 16 carries a pair of

sheet metal assemblies

20 and 22, the assembly 20 having its lower wall thereof engaging the insulating base 16 and the assembly 22 overlying the assembly 20. The sheet metal assembly 22 has portions cut away to form the

spring arms

24, 26, 28 and 30. In a like manner the sheet metal assembly 28 is formed with cut away sections to provide

spring arms

32, 34, 36 and 33 which are positioned directly be.ow

thespring arms

24, 26, 28 and 30. The

spring arms

32, 34, 36 and 38 respectively carry

contacts

40, 42, 44 and 46 as is clearly apparent from the drawings.

"ice

It can be seen from the sectional views of FIGURES 2 and 6 that the contacts 40 through 46 have portions projecting on either side of a respective contact arm, the portion extending from the top side thereof engaging the respective spring arms '24, 26, 28 and 30. The sheet metal assemblies 20 and 22 with their integral spring arms are held to the insulating base 16 by means of a rivet 48 and a terminal 50.

The insulating base 16 carries a pair of

strap connectors

52 and 54. The strap connector 54 is better illustrated in the plan view of FIGURE 7 and it is seen that it has a central opening which slips over the central projection 18 formed integrally with the insulating base 16. The strap connector 54 has a pair of

upturned contact arms

56 and 58. In a like manner, the strap connector 52 is provided with

upturned contact arms

60 and 62. The strap connector 52 also has a central opening which slips over the upstanding post 18. As can be seen from the sectional view of FIGURE 2 the strap connector 52 is positioned in contact with the insulating base 16 where as the strap connector 54 is spaced from the strap connector '52 by a sheet of insulating material 64. The

strap connectors

52 and 54 preferably fit in recesses formed in the insulating base 12 and are held with respect to the post 18 by a fastener 66. The strap connector 52 is further held to the base by a terminal 68 whereas the strap connector 54 is further held to the base by a terminal 70. It can be seen that the terminal 68 is electrically connected with the strap connector 52 and that the terminal 70 is electrically connected with the strap connector 54.

The insulating base 16 carries terminals 72 and 74 and rivets 76 and 78. The terminal 72 is connected with n'vet r 76 by a strap connector 80 whereas the terminal 74 is connected with rivet 78 by the strap connector 82. The head of terminal 72 is positioned directly below the contact 40 so as to be engaged by this contact when the

arms

24 and 32 are deflected downwardly. In a like manner, the head of terminal 74 is positioned directly below the contact 42 whereas the heads of

rivets

76 and 78 are respectively located directly below

contacts

46 and 44.

The circuit controller of this invention is provided with a manual actuator which is generally designated by reference numeral 84. This actuator has a handle portion 86 and a spherical portion 88 which engages the portion 9% of the housing 10. The actuator has a portion 92 formed with spherical walls that ride on the top end of the projecting post 18. In addition, the actuator 84 is formed with arms 94 which are positioned directly over the

spring arms

24, 26, 28 and 30. The

spring arms

24, 26, 28 and 30 serve to urge the spherical portion 88 of the actuator into engagement with the housing 10 and also serve to bias the actuator 84 to its FIGURE 2 position.

The circuit controller of this invention operates to complete a plurality of circuits when the actuator 84 is moved leftwardl-y or rightwardly in FIGURE 2 or in a plane perpendicular to this movement. In using this switch the terminal 50 is the power terminal and is connected to one side of a power source such as a battery. When the switch is used with one type of seat adjusting transmission the terminal 70 will be connected to a vertical solenoid whereas the terminal 68 will be connectedto horizontal solenoid. The terminals 72 and 74 are motor terminals and provide respectively counterclockwise and clockwise rotation thereof.

If the actuator knob 86 is moved rightwardly in FIG- URE 2 it can be seen that the

spring arms

24 and 32 will be deflected and that the contact 40 will become engaged with the head of terminal 72. Since the power terminal 50 is connected with both

sheet metal assemblies

20 and 22 it can be seen tht the rightward movement of the handle 86 will cause power to be applied to the counterclockwise motor terminal 72. This rightward movement of handle 86 will also cause the contact 40 to become engaged with the upstanding spring finger 60' carried by strap connector 52. This will thus cause power to be applied to the strap connector 52 and to the terminal 68 which is connected therewith.

If the actuating handle 84 were moved leftwardly in FIGURE 2 the contact 44 would be shifted down into e11- gagement with the head of rivet 78. This would cause power to be applied to the clockwise motor terminal 74 via the rivet 78 and the strap connector 82. In addition, this movement of the actuator 84 to the left will cause the spring finger 62 to become engaged with the contact 4-4 so that the terminal 68 is once more connected with the power terminal 50. It can be seen from the foregoing that shifting of the actuating handle 86 leftwardly or rightwardly in FIGURE 2 will cause the horizontal solenoid terminal 68 to be energized in either direction of movement of the handle 86- and will cause the motor terminals 72 and 74 to be alternately energized depending upon the direction of movement of the handle 86.

If the actuating handle 86 were moved rearwardly in FIGURE 2 the cont-act 46 will be moved down into engagement with the rivet 76, thus connectin the power terminal with terminal 72 via the strap connector 80. The contact 46 will likewise engage the spring finger contact 58 to cause the power terminal 50 to be connected with the strap connector 54. If the handle 86 were now moved toward the viewer in FIGURE 2 the contact 42 will be moved down into engagement with the head of terminal 74 and the spring finger 56 will be moved down into engagement with the head of rivet 70. This will efifectively connect the power terminal 50 with the terminal 74 and with the terminal 70. It thus can be seen that'this type of movement will always cause the vertical solenoid terminal 70 to be energized and will alternately energize the terminals 72 and 74.

It will, 04: course, be appreciated that after each actuation of the handle 86 the handle is returned to the FIG- URE 2 position by the

spring arms

24, 26, 28 and 30. The

spring arms

32, 34, 36 and 38 which carry the con tacts are not unduly stressed by the construction of this switch since they are not required to move the actuating handle 86 back to a neutral position after it has been shifted to some circuit closing position.

While the embodiments of the present invention as herein disclosed constitute a preferred form, it is to be understood that other forms might be adopted.
