Abstract
Abstract A snap-action electric switch having an overcenter mechanism including oppositely bowed spring leaves pivotally anchored with their adjacent ends to opposite insulating members, respectively, and being extended in passing of the mechanism from either stable position through a dead center position to the other stable position, with at least one of the spring leaves having at its ends bent lugs with contacts which on extension of the leaf undergo angular displacement so as to have a wiping action on associated fixed contacts on their engagement therewith.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
173 words
A snap-action electric switch, having a contact assembly with a pair of rigid compression members, a central operating member from which said compression members extend outwardly, a pair of resiliently flexible members extending along the length of the assembly, and insulating members to which the adjacent ends, respectively, of said flexible members are attached with pivotal freedom, and which are also engaged by said compression members, with said members defining an overcenter mechanism capable of transfer from one stable position to the other stable position through a dead center position under the control of said operating member, at least one of said flexible members serving as a conductive bridge and having at its ends moving contacts lying in a plane at right angle to that of said bridging member, and fixed contacts associated with said moving contacts, with said moving contacts undergoing angular displacement as a result of extension of said bridging member in passing from one stable position to the other and thereby exerting a wiping action on said associated fixed contacts.
Claim 2
Dependent Claim
173 words
A snap-action electric switch, having a contact assembly with a pair of rigid compression members, a central operating member from which said compression members extend outwardly, a pair of resiliently flexible members extending along the length of the assembly, and insulating members to which the adjacent ends, respectively, of said flexible members are attached with pivotal freedom, and which are also engaged by said compression members, with said members defining an overcenter mechanism capable of transfer from one stable position to the other stable position through a dead center position under the control of said operating member, at least one of said flexible members serving as a conductive bridge and having at its ends moving contacts lying in a plane at right angle to that of said bridging member, and fixed contacts associated with said moving contacts, with said moving contacts undergoing angular displacement as a result of extension of said bridging member in passing from one stable position to the other and thereby exerting a wiping action on said associated fixed contacts.
Claim 3
Dependent Claim
28 words
A snap-action electric switch as in claim 1, in which both of said flexible members serve as conductive bridges with each having said moving contacts at its ends.
Claim 4
Dependent Claim
52 words
A snap-action electric switch as in claim 2, in which each of said bridges is at its ends formed with bent over lugs carrying the movable contacts, with said lugs of each bridge lying in the same plane and being spaced from said lugs of the other bridge by said insulating members.
Claim 5
Dependent Claim
29 words
A snap-action electric switch as in claim 1, in which said operating member and said insulating members have grooves in which said compression members are received with their ends.
Claim 6
Dependent Claim
31 words
A snap-action electric switch as in claim 1, in which said flexible members are spaced, and said operating member and compression members are arranged in the space between said flexible members.
Claim 7
Dependent Claim
20 words
A snap-action electric switch as in claim 1, in which said flexible members are formed by oppositely bowed spring leaves.
Claim 8
Dependent Claim
40 words
A snap-action electric switch as in claim 1, in which said flexible members have openings in their opposite ends, and said insulating members have projections extending through said openings to hold said flexible members at their ends with pivotal freedom.
