INVENTOR. Albert J. Colau/f/ H/s Attorney Unit d Stat s P 2,909,624 CIRCUIT CONTROLLER Application July 3, 1e51, Serial No. 669,744 1 Claims. '(Cl. zoo-45 This invention relates to electric switches and is more particularly concerned with a switch structure wherein a plurality of actuators are maintained in a neutral posi tion by a single spring member.

-Itjis an object of the present invention to provide an improved simplified switch structure wherein a single spring and a single contact actuator will maintain an actuator in a neutral position.

A further object of the present invention is to provide a switch structure wherein a plurality of slidable actuators are maintained in position in a switch housing by a single spring'and single contact actuator.

. Another object of the present invention is to provide a switch structure wherein a plurality of switch actuators which are slidable in parallel spaced recesses in the switch housing are constantly urged to a neutral position in the housing by asingle spring and a single contact actuating memberw, T. r f

A still further object of the present invention is to pro videia circuit controller structure wherein a plurality of separate switch elements each disposed side by side in a row ina unitary housing, each have an individual switch actuator that extends through. an opening in the housing and is slidably -maintained in a neutral position in the housing by a unitary spring member and a unitary member which carries all-of the movable contacts of the switch and wherein the spring and contact carrying members are both secured to a unitaryswitch base to prevent the switch parts from rattling. Further, objects and advantages of the present invention wi 1l.beiapparentfrom the following description, reference being had to the accompanying drawingswherein preferred form of the invention is clearly shown.

In the drawings:

. Figure 1 shows a top plan view of the switch according to the present invention with aportion of the switch housingbroken away to show the arrangement of the internal parts of theswitch.

, Figure 2 is a cross-sectionalview taken along line 22 in Figure 1. f

Figure 3 is a view showing a major portion of the switch parts in Figure 2 in a contact closing position.

Figure 4 is a cross-sectional view taken along line 4-4 in Figure 1.

Figure 5 is an enlarged cross-sectional view showing the securement of the switch parts by a common terminal.

- twoparalle l isides of each otthe openings 28 are runners 30 which are formed of the material of the housing 22 and located as shown.

In Figure 5 of the drawings, a spring member 32, an

2,909,624 Patented oct zo, 1959 ICC g,

insulator 34, a movable contact support blade 36, and a nylon shoe insulator 38 together with an insulating washer 40 are shown as secured to the base 20 by a common terminal member 42. These members are also secured at other points to the base by rivets 44 as shown in Figures 1-3.

The spring member 32 is most clearly seen in Fig. 6 of the drawings. This spring member is formed of a single strip of spring metal and will constantly urge the switch actuators or buttons 46 to a neutral position in openings 28 as will become hereinafter apparent. The spring member 32 has a mid-portion 48 secured to the base 20 by the common terminal member 42 which extends through opening 50 and the rivets 44 which extend through the openings 52. Disposed along the edges of the midportion 48 are the spaced extending arms 54. These arms are bent relative to the midportion 48 to constantly engage the buttons 46 as shown in Figure 2. Extending between a portion of each of the arms 54 and the midportion 48 arenotches 56. The portion of the notch 56 which is disposed in the midportion 48 is sized to provide clearance between the spring member 32 and the stationary contacts 58. The stationary contacts 58 are secured in spaced relation to one another on the base 20 and are located relative to the buttons 46 as shown in Figure 1. Each of the buttons 46 has a pair of spaced stationary contacts associated therewith.

The spring member 32 is insulated from the terminal 42 and the contact support blade 36 by insulating washer 40 and insulator 34. The contact support blade 36 is also formed of a unitary strip of metal to have a central portion 60 from which the blade arms 62 extend. The central portion 60'is provided with suitable openings to permit its securement to the base by the common terminal 42 and rivets 44. The blade arms 62 are arranged to extend into notches 56 and each have a movable contact 64 secured thereto which is arranged to engage one of the stationary contacts of the switch when the arms 62 are pressed downwardly from the position shown in Fig. 2 to the position shown in Figure 3.

The shoe insulator 38 is also provided with a central portion 66 which is secured by the common terminal 42 and rivets 44 to the base 20. Extending upwardly from the central portion 66 are lugs 68 which are located as shown in Figures 1 and 4 and sized to provide a predetermined distance between the top surface of the lugs 68 and bottomjsurfaceoffthe runners 30. Branching outwardly from the central portion 66 and arranged to embrace the top surface of each of the blade arms 62 of the contact support blade 36 are arm portions 70 most clearly shown in Figures 2 and 3. These arm portions 70 will serve to electrically insulate the contact support blade 36 from the buttons 46.

The shape of the actuator buttons 46 is most clearly seen in Figures 2 and 4 of the drawings. Each of the buttons has a handle portion 72 which extends into openings 28. The portion, of the actuator disposed within the switch housing adjacent the handle portion 72 is provided with shoulders 74 which will slidingly engage the runners 30. The-actuator is also provided with asurface 76 which will slidingly engage the top surface of the lugs 68 to permit a sliding movement of the buttons 46 inthe openings 28. Downwardly extending from the bottom surface of the buttons 46 are extending lugs 78 which are in constant engagement with the arm portions 70 of the shoe insulator 38. The shoe insulator 38 is' normally urged upwardly into tight engagement with the lugs 78 by the force of the blade arms 62 to maintain the buttons .46 in tightengagement with the runners 30 .and thereby prevent rattling of the switch parts.

From the above it is apparent that when any one of the buttons 46 are moved in either direction from the neutral position as for example moved to the left from the posi- 7 tion shown inFig. 2 to the position shown in Figure 3, one of the lugs 78 will ride upon an inclined surface 80 of one of the arms 70 to force the proper blade arm 62 downwardly until the proper contact 64 engages the proper stationary contact 58 which is associated with the terminal 82 to complete a circuit between the common terminal 42 and one of the terminals 82. Thus, whenever any one of the buttons 46 are moved in either direction from the neutral position, a circuit will be completed between the common terminal 42 and the terminal 82 toward which the button 46 was moved.

- In the preferred embodiment of the invention, the shoe insulator 38 is formed as a molded nylon part. This will provide a good bearing and wear surface for the sliding movement of lug 78 on the arm portions 70. The arms 54 of the unitary spring member 32 are arranged to engage each one of contact actuators 46 to normally maintain the handles 72 in alignment.

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