Toggle actuator assembly for electric switch

Claim 2

An electrical switch comprising a case, a support yoke positioned in said case, an electrically conductive contact lever pivotally mounted on said yoke, a toggle handle pivotally mounted on said case, a movable lever actuator in said case for pivotally operating said contact lever, first means on said handle and second means on said actuator cooperating telescopically whereby the pivoting action of said toggle handle produces the pivoting action of said actuator and of said lever, said first means and said second means having slidably mating cross section contours which prevent axial rotation of either the toggle handle or the actuator in respect of the other, spring means between said toggle handle and said actuator for yieldably urging the latter against said contact lever, third means on said actuator and fourth means in the interior of said case, said third and fourth means cooperating with each other during the pivoting movement of said actuator to prevent the latter from rotating on its axis during its pivoting movement between the end portions of said case.

Claim 3

A switch according to claim 1 wherein said toggle handle is mounted in a ball and socket arrangement in respect of said case, and wherein said spring urges said ball and socket arrangement into sliding engagement for the pivoting action of said toggle handle.

Claim 4

A switch according to claim 1 wherein said first means comprises a recess in said toggle handle, and said second means comprises a stem on said actuator.

Claim 5

A switch according to claim 1 wherein said first means comprises a stem on said toggle handle and said second means comprises a recess in said actuator.

Claim 6

A switch according to claim 1 wherein said third means comprises a pair of spaced apart side walls on said actuator and said fourth means comprises the parallel interior spaced apart walls of said case, the adjacent respective side walls of said actuator and of said case being in close sliding proximity to each other.

Claim 7

An electrical switch comprising a case, a support yoke positioned in said case, an electrically conductive contact lever pivotally mounted on said yoke, a toggle handle, a curved boss on said toggle handle intermediate the ends thereof, an annular bearing seat in said case, said boss and said seat forming a pivoting juncture for said toggle handle, a movable lever actuator in said case for pivotally operating said contact lever, telescoping means between said toggle handle and said actuator whereby the pivoting movement of said toggle handle causes the pivoting movement of said actuator, said telescoping means having a cross-section contour that prevents axial rotation of either said toggle handle or said actuator in respect of the other, spring biasing means between toggle handle and said actuator for yieldably urging the latter against said contact lever and for maintaining the sliding engagement of said boss and said seat, and the sidewalls of said actuator and of the interior walls of said case being in sliding engagement to prevent the axial rotation of said actuator during its pivoting movement between the end portions of said case.

Claim 8

An electrical switch comprising a case, a support yoke positioned in said case, an electrically conductive contact lever pivotally mounted on said yoke, a toggle handle, a curved boss on said toggle handle intermediate the ends thereof, an annular bearing seat in said case, said boss and said seat forming a pivoting juncture for said toggle handle, a movable lever actuator in said case for pivotally operating said contact lever, telescoping means between said toggle handle and said actuator whereby the pivoting movement of said toggle handle causes the pivoting movement of said actuator, said telescoping means having a cross-section contour that prevents axial rotation of either said toggle handle or said actuator in respect of the other, spring biasing means between toggle handle and said actuator for yieldably urging the latter against said contact lever and for maintaining the sliding engagement of said boss and said seat, and the sidewalls of said actuator and of the interior walls of said case being in sliding engagement to prevent the axial rotation of said actuator during its pivoting movement between the end portions of said case.

Claim 9

A switch according to claim 6 wherein the side walls of the actuator and of the interior of the case are in parallel array.

Claim 10

A switch according to claim 6 wherein said telescoping means comprises a stem on one and a recess on the other of said toggle handle and of said actuator, said stem and said recess having similar cross section contours and being longitudinally slidable one within the other.

Claim 11

A switch according to claim 8 wherein said cross section contours are noncircular in shape.
