ELECTRIC SWITCH Filed June 25, 1954 INVENTOR. Fig: 4 Ken/73th W Young His Afibmey ELECTRIC SWITCH Kenneth W. Young, Anderson, Ind., assignor to General Motors Corporation, Detroit, Mich., a corporation of Delaware Application .lune 25, 1954, Serial No. 439,343

14 Claims. (Cl. 2tl06) This invention relates to electric switches and more particularly to a switch wherein the parts are normally held in a neutral position.

It is an object of the present invention to provide a switch wherein the various movable parts of a switch are normally held in a neutral open circuit position by a spring that is so disposed between a cover for the switch and an actuating handle that the spring acts as a pivot for the handle and resists its movement from the neutral position.

It is a further object of the present invention to provide a switch with spaced contacts, and a center contact which acts as a pivot for a movable contact plate that is adapted to selectively engage all of the contacts and a means to pivot the plate which includes a handle that embraces a central portion of the contact plate and is urged to a neutral position by a spring that is disposed between the switch housing and a portion of the handle so that it may act as a pivot for the handle.

It is another object of the present invention to provide a cruciform shaped housing of insulating material for a switch to carry four radially spaced stationary contacts and a central contact that is positioned intermediate said stationary contacts so that the central contact may act as a pivot for a movable contact plate of cruciform shape when the movable contact is pivoted into engagement with any one of the spaced contacts by an operating handle that embraces the central portion movable contact as the handle is moved from a neutral position against the force of a conically shaped spring that is seated on the housing and handle and acts as a pivotal support for the handle.

Further objects and advantages of the present invention will be apparent from the following description reference being had in the accompanying drawings wherein a preferred embodiment of the present invention is clearly shown.

In the drawing:

Figure l is a plan view of a switch according to the present invention.

Figure 2 is a view partly in section along line 22 in Figure 1.

Figure 3 is a view partly in section along line 33 in Figure 1.

Figure 4 is a view along line 44 in Figure 3.

Figure 5 is an exploded view showing various parts of the switch in Figure l in perspective.

In the drawing the numeral 20 designates a switch which comprises an insulated base 22, preferably of a molded phenolic condensation product and filler that is preferably cruciform in shape to define a correspondingly cruciform shaped recess 24 wherein the various parts of the switch are included. The recess 24 is closed by a cruciform shaped cover 26, suitably secured to base 22, that has a cruciform shaped centrally located aperture 28 which is visible when the remainder of cover 26 is concealed if an ornamental bezel 30 is utilized.

' The recess 24 because of its cruciform shape defines atent O four radially extending recess portions at right angles to each other and a central recess portion which interconnects each of the radial portions. A stationary contact 32 is disposed in each of the four radial recess portions and a central contact 34 is located in the central recess portion so that it is intermediate the contacts 32. Thus a cruciform plate 36 when included in recess 24 and pivoted on central contact 34 may be moved to selectively engage any one of the stationary contacts 32.

An actuating handle 38, preferably formed of insulating material and most clearly seen in Figure 5, comprises an actuating end 40, which is manually movable, and an actuated end 42, that is received within the recess 24. End 42 has an extending flange or shoulder 44 wherefrom four projections 46 extend. Flange 44 and projections 46 are sized and shaped so the projections 46 will embrace the central portion of the cruciform contact plate 36 located between the intersecting arm portions thereof and the bottom surface of flange 44 will on gage the surface of the center of the contact plate 36.

A conically shaped spring 43, which surrounds the end 42 of the actuating handle 38, has one end seated on cover 26 and its other end resting or bearing on the top surface of shoulder or flange 44. This spring 48 not only acts as a pivot for handle 38 when it is moved relative to base 22 and cover 26, but it also serves to constantly maintain the end flange 44 and projections 46 in the embraced position relative to contact plate 36 so the contact plate 36 is constantly urged to a neutral position on contact 34 and out of engagement with stationary contacts 32. Thus when handle 33 is moved against the force of spring 48 contact 36 Will be pivoted on contact 34 to engage one of the stationary contacts 32 and cause the closing of a circuit between the central contact 34 and the particular stationary contact 32 in the arm of the recess 24 toward which the handle 38 is pivotally moved.

It is clearly apparent that the switch according to the present invention may be used to selectively control any one of four circuits if the central contact is connected to lead that is common to each of the four circuits. Thus if the central contact is connected with the source and the four radially located switches are properly connected with various pieces of electrical equipment, the switch may selectively control any of the circuits as desired as for example circuits to raise or lower and to move forward or backward the occupants seat in a vehicle.
