Abstract
Abstract A circuit breaker having a pair of spaced insulated stationary contacts engageable by a pair of movable contacts mounted to a conducting bridge on a movable contact arm is provided with common means defining main and auxiliary pivot axes for the contact arm. The main axis is transverse to the arm and provides a center about which the movable contacts pivot as they separate from the stationary contacts. The auxiliary axis is parallel to the longitudinal axis of the arm and provides a center for limited pivoting of the arm to obtain automatic seating of the movable contacts on the stationary contacts.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
238 words
A switch device including stationary contact means positioned generally in a first plane, movable contact means operable into and out of engagement with said stationary contact means, an elongated arm having said movable contact means mounted thereto at its forward end, means defining a main axis positioned to the rear of said movable contact means, said movable contact means being mounted for pivotal movement about said main axis as a center to disengage said stationary contact means, with said pivotal movement being generally in a second plane at right angles to said first plane, said stationary contact means including spaced first and second contacts insulated from one another when said switch device is open, said first and second contacts being positioned so that a line extending therebetween is generally parallel to said main axis, said movable contact means includes third and fourth contacts engageable with the respective first and second contacts, a rigid conducting bridge to which said third and fourth contacts are fixedly mounted, said bridge comprising a conducting path between said first and second contacts when said switch device is closed, and means defining a single auxiliary axis about which said movable contact means is pivotable to seat said movable contact means in engagement with said stationary contact means, said auxiliary axis extending generally parallel to the longitudinal axis of said arm and at right angles to said first axis generally parallel to said second plane.

A switch device including stationary contact means positioned generally in a first plane, movable contact means operable into and out of engagement with said stationary contact means, an elongated arm having said movable contact means mounted thereto at its forward end, means defining a main axis positioned to the rear of said movable contact means, said movable contact means being mounted for pivotal movement about said main axis as a center to disengage said stationary contact means, with said pivotal movement being generally in a second plane at right angles to said first plane, said stationary contact means including spaced first and second contacts insulated from one another when said switch device is open, said first and second contacts being positioned so that a line extending therebetween is generally parallel to said main axis, said movable contact means includes third and fourth contacts engageable with the respective first and second contacts, a rigid conducting bridge to which said third and fourth contacts are fixedly mounted, said bridge comprising a conducting path between said first and second contacts when said switch device is closed, and means defining a single auxiliary axis about which said movable contact means is pivotable to seat said movable contact means in engagement with said stationary contact means, said auxiliary axis extending generally parallel to the longitudinal axis of said arm and at right angles to said first axis generally parallel to said second plane.
Claim 3
Dependent Claim
22 words
A switch device as set forth in claim 1 in which the main and auxiliary axes intersect at a common arcuate means.
Claim 4
Dependent Claim
30 words
A switch device as set forth in claim 1 also including a movable support to which said arm is movably connected by the means defining the main and auxiliary axes.
Claim 5
Dependent Claim
22 words
A switch device as set forth in claim 3 in which the main and auxiliary axes intersect at a common arcuate means.
Claim 6
Dependent Claim
20 words
A switch device as set forth in claim 4 in which the arcuate means is fixedly mounted to the arm.
Claim 7
Dependent Claim
21 words
A switch device as set forth in claim 4 in which the arcuate means is fixedly mounted to the movable support.
Claim 8
Dependent Claim
18 words
A switch device as set forth in claim 6 in which the arcuate means comprises a spherical element.
Claim 9
Dependent Claim
20 words
A switch device as set forth in claim 7 in which the conducting bridge is disposed forward of said axes.
Claim 10
Dependent Claim
42 words
A switch device as set forth in claim 8 in which the arcuate means is at the forward end of said movable support, and means at the rear of said movable support mounting the latter for movement generally in said second plane.
Claim 11
Dependent Claim
20 words
A switch device as set forth in claim 1 in which the conducting bridge is disposed forward of said axes.
