Abstract
Abstract A manually operated switch having a toggle mechanism which applies positive pressure between the contacts of the switch during the interval the toggle levers are passing through the toggle centerline. The switch includes a jog function lever which is selectively movable between an operative position which will cause the levers of the toggle mechanism to return with a snap toggle action from a position which causes the contacts of the switch to be closed to a position wherein the contacts of the switch are open when a manual force on the ON button or lever is removed when the jog function lever is at one position and which will permit the toggle mechanism to move and remain in the position whereat the contact of the switch remain closed after the manual force which is used to actuate the ON button or lever is removed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
421 words
In an electric switch, the combination comprising: a switch housing providing an internal cavity, a contact carrier movable along a linear path within the cavity between a contact opening and a contact closing position, resilient means constantly urging the carrier to the contact opening position, a toggle mechanism within the cavity, said toggle mechanism including an operating lever, means providing access to the operating lever from the exterior of the housing for moving the operating lever about a main pivot between an OFF position and an ON position when a manual force is applied through the means to the operating lever from the exterior of the housing, a toggle lever rotatable about an auxiliary pivot between a deactivated position and an activated position, said toggle lever having a portion engaging the contact carrier for moving the carrier from the contact opening position to the contact closing position when the toggle lever is moved from the deactivated position to the activated position, and a toggle spring having its opposite ends connected between the operating lever and the toggle lever, said toggle spring providing a connection between the operating lever and the toggle lever for moving the toggle lever with an overcenter toggle action between its deactivated and activated positions when the operating lever is moved respectively between its OFF and ON positions and for maintaining the toggle lever and the operating lever respectively in the deactivated position and the OFF position when the operating lever is manually moved to the OFF position and the manually applied force on the operating lever is removed and for maintaining the toggle lever and the operating lever respectively in the activated position and the ON position when the operating lever is manually moved to the ON position and the manually applied force is removed, and a means providing the switch with a jog function, said jog providing means including a jog lever having a portion pivotally mounted within the cavity and a portion extending external of the housing for selectively moving portions of the jog lever to two positions within the cavity, and a resilient means carried by said portion of the jog lever within the cavity to engage portions of the operating lever when the jog lever is in one selected position for supplying a force for automatically moving the operating lever and the toggle lever respectively to the OFF position and the deactivated position when the operating lever is in the ON position aNd the manually applied force on the operating lever is removed.

In an electric switch, the combination comprising: a switch housing providing an internal cavity, a contact carrier movable along a linear path within the cavity between a contact opening and a contact closing position, resilient means constantly urging the carrier to the contact opening position, a toggle mechanism within the cavity, said toggle mechanism including an operating lever, means providing access to the operating lever from the exterior of the housing for moving the operating lever about a main pivot between an OFF position and an ON position when a manual force is applied through the means to the operating lever from the exterior of the housing, a toggle lever rotatable about an auxiliary pivot between a deactivated position and an activated position, said toggle lever having a portion engaging the contact carrier for moving the carrier from the contact opening position to the contact closing position when the toggle lever is moved from the deactivated position to the activated position, and a toggle spring having its opposite ends connected between the operating lever and the toggle lever, said toggle spring providing a connection between the operating lever and the toggle lever for moving the toggle lever with an overcenter toggle action between its deactivated and activated positions when the operating lever is moved respectively between its OFF and ON positions and for maintaining the toggle lever and the operating lever respectively in the deactivated position and the OFF position when the operating lever is manually moved to the OFF position and the manually applied force on the operating lever is removed and for maintaining the toggle lever and the operating lever respectively in the activated position and the ON position when the operating lever is manually moved to the ON position and the manually applied force is removed, and a means providing the switch with a jog function, said jog providing means including a jog lever having a portion pivotally mounted within the cavity and a portion extending external of the housing for selectively moving portions of the jog lever to two positions within the cavity, and a resilient means carried by said portion of the jog lever within the cavity to engage portions of the operating lever when the jog lever is in one selected position for supplying a force for automatically moving the operating lever and the toggle lever respectively to the OFF position and the deactivated position when the operating lever is in the ON position aNd the manually applied force on the operating lever is removed.
Claim 3
Dependent Claim
90 words
The combination as recited in claim 1 wherein the resilient means carried by the jog lever includes a spring return lever that is rotatably mounted on the portion of the jog lever within the cavity, a stop carried by said portion of the jog lever for limiting the rotation of the spring return lever in one direction and a spring having its opposite ends reacting between the jog lever and the spring return lever providing a force for constantly urging the spring return lever in said one direction of rotation.
Claim 4
Dependent Claim
74 words
The combination as recited in claim 2 wherein the spring return lever includes a portion that is aligned to be engaged by portions of the operating lever when the jog lever is at a first of said two positions and the operating lever is moved to the ON position and to be out of the path of movement of said operating lever when the jog lever is at a second of said two positions.
Claim 5
Dependent Claim
49 words
The combination as recited in claim 3 wherein the spring return lever includes a portion that is engageable with portions of the operating lever for preventing the jog lever from being moved from the second position to the first position when the operating lever is at the ON position.
Claim 6
Dependent Claim
35 words
The combination as recited in claim 4 wherein the operating lever and the toggle lever move in parallel planes and the jog lever is movable in a plane that is perpendicular to the parallel planes.
Claim 7
Dependent Claim
35 words
The combination as recited in claim 1 wherein the operating lever and the toggle lever move in parallel planes and the jog lever is movable in a plane that is perpendicular to the parallel planes.
Claim 8
Dependent Claim
46 words
The combination as recited in claim 5 wherein the toggle spring has an end connected to an end portion of the operating lever and the spring return lever has a portion engageable with the end of the operating lever to which the toggle spring is connected.
