HARMON ELECTRIC ROCKER SWITCH FOR CONTROLLING MULTIPLE CIRCUITS WITH MAGNETIC COUPLING MEMBERS This invention relates in general to manual electric switches and more particularly to a rocker type manual electric switch for movement to two "on" positions from a neutral oI'P' position with terminals for controlling a plurality of different circuits.
Prior manual electric switches, particularly of the button, toggle, and rocker type employ over-center spring means for holding the switch in an "off" off position or with the contacts together and the terminals thereof adapted to control relatively few circuits.
The present invention overcomes the above mechanical disadvantages and circuit limitations and is adapted to low cost manufacture by the provision of a rocker type switch which is held in each of its two operating positions by permanent magnets. The switch is provided with six external tenninals for providing a large number of electric circuits.
These and other objects and advantages in one embodiment of the invention are described and shown in the following specification and drawings, in which:

FIG. 24 is a schematic diagram showing connections for off-on" circuits to two independent loads.
FIG. 25 is a schematic diagram of a pair of lines connected to independent terminals for connection to a corresponding pair of independent load terminals.
FIG. 26 is a schematic diagram of the terminal connections for maintaining a through circuit and simultaneously opening or closing two independent load circuits.
Referring to FIG. I, a switch body 1 is molded from plastic material having high dielectric properties, such as polycarbonate, and is of generally rectangular shape and has a stamped metal mounting plate 2 secured to the body I by a pair of ears 3 laterally positioned at opposite sides of the plate for snap-on engagement with outstanding projections from opposite sides of the body I. A manual actuated rocker 4 is pivotally mounted in body 4, by means to be hereinafter described, and extends through a clearance aperture in the mounting plate 2. The rocker has a divergent upper surfaces A and B for designating operating positions. The plate 1 is provided with suitable holes through opposite extensions for mounting purposes.
Referring to FIGS. I, 2, and 4, the rocker 4 has molded therein a transverse shalt 5 having an integral cam 6 on one end thereof with a transverse V notch therein, better shown in FIG. 2. The rocker is pivoted for oscillation about axis a-a by a pair of bearings formed by cars 7-7, which are integral with the opposite sides of plate 2. A vertical bore 8 in one side of the body I directly below the axis a-a retains a spring 9 and a ball III, which ball is urged into contact with the V groove in cam 6, forming a self-centering detent, as shown in FIG. 2. It is now apparent that when the rocker 4 is alternately depressed from either the A or B side, the spring will tend to urge the rocker return to its central or off position, as shown in FIG. 2.
The cross sectional view, FIG. 3, shows a pair of permanent magnets lI-II molded into pillars I2-l2 positioned centrally within opposite ends of the body I. The magnets are retained in the molded body I by suitable shape or by projections extending therefrom. The rocker 4 also has a pair of like permanent magnets I3 molded in integral opposite central projections, as shown, with the outer surface of each magnet I3 thereof adapted to mate with the upper surface of each magnet II when the rocker is operated.
Referring to FIGS. 5 and I I, the rocker has a pair of electric contacts I414 secured in opposite ends of a conducting bridge 15, which bridge is molded transversely into the "A portion of the rocker with the contacts I4 projecting therefrom, as shown in FIG. I0.
A second pair of contacts 14- I4 are secured to a conducting bridge I6, which is molded into the "B" portion of the rocker with the contacts projecting therefrom, as shown.
A third pair of contacts l4-I4 are secured to conducting bridge I7 and molded in predetermined spaced relation to bridge 16 in the 8" portion of the rocker.
FIG. 11 shows a common conducting terminal bracket I8 which electrically connects three of the contacts M] in different positions and provides for three terminal screws, which bracket is shown in operative position in FIG. 5 retained within the body I by screws I9. A terminal bracket 10 provides for a terminal screw 19 carrying a contact l4], shown in FIG. 5, secured in the body I by a fourth screw 19.
Referring to FIG. 8, a terminal bracket II is secured in the opposite side of the base I by a fiflh screw 19 and a sixth bracket 12 is positioned on the same side as the bracket 21 and retained by screw I9.
In operation and referring to FIGS. I and 2, the rocker 4 is held in its idle or "of!" position by the action of spring 9 urging the ball 10 into the V groove in cam 6. When the "B side of the rocker is manually depressed the spring 9 will be depressed by the action of cam 6 and the ball I0 and the rocker will assume an "on" position, shown in FIG. 7, and will be held in the on position by the mutual attractive force of magnets II and I3, shown in FIGS. 6 and 9.
The rocker will be returned to its normal olf" position by relatively light pressure on portion A" of the rocker or near balanced pressure between .A" and 8" thereof, which breaks the holding force and permits the spring 9 to return the rocker to its "of!" position.
lt is now apparent that when the portion "A" of the magnet is depressed, the earn 6 will overcome the spring 9 and permit the mutual attraction of the opposite magnets 11 and 13 to hold the rocker in a position opposite to that shown in FIG. 7 and likewise permit the return to its idle off position by slight pressure on the B" portion of the toggle or slightly unbalanced pressure on both "A" and B portions, but favoring the B" portion.
Referring to FIG. 18, the electric conducting bridges and brackets are shown in their relative positions and are formed from low resistance material with the brackets threaded to receive screws 19 under which lugs or electric conductors may be secured.
The six terminal screws 19 and corresponding contacts are illustrated schematically in FIG. 12 and may be connected to control a large number of different circuit formations, such as shown in FIGS. 13 26. However, the connections are not limited to the fourteen different circuit formations shown.
This invention comprehends certain modifications in construction that fall within the teachings and scope of the above specification.
