Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
An electrical switch comprising first and second electrically conductive contact members, said first and second contact members having first and second portions, respectively, in substantially parallel, spaced arrangement, a shorting means in substantially parallel, spaced relationship with respect to said first and second portions, said shorting means including a support member having an outside surface defined by a firSt diameter, a plurality of electrically conductive disc members supported by said support member, said disc members having an inside diameter greater than said first diameter of said support member, actuation means for urging said disc members into engagement with said first and second portions of said first and second contact members, and biasing means yieldably urging said shorting means away from said first and second portions when said actuation means is deactuated.
Claim 2
Dependent Claim
131 words
An electrical switch comprising first and second electrically conductive contact members, said first and second contact members having first and second portions, respectively, in substantially parallel, spaced arrangement, a shorting means in substantially parallel, spaced relationship with respect to said first and second portions, said shorting means including a support member having an outside surface defined by a firSt diameter, a plurality of electrically conductive disc members supported by said support member, said disc members having an inside diameter greater than said first diameter of said support member, actuation means for urging said disc members into engagement with said first and second portions of said first and second contact members, and biasing means yieldably urging said shorting means away from said first and second portions when said actuation means is deactuated.
Claim 3
Dependent Claim
