Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
229 words
A multiple contact switching apparatus, comprising: a non-conductive housing including a plurality of individual compartments, said housing including integral wiring paths terminating at fixed contacts, each of said compartments including fixed contacts connected to respective ones of said wiring paths, a support member, and an opening; a plurality of switching mechanisms each mounted respectively in one of said compartments, each of said switching mechanisms comprising, an operating lever mounted on said support member, said operating lever including spaced switching fingers and an element extending through said opening outside said housing; a contact bridge mounted on said operating lever and extending over said switching fingers, said contact bridge including spaced contact elements aligned with corresponding contacts on said housing, support means extending from said contact bridge and in contact with said housing; means interconnecting said operating lever and said contact bridge for biasing said contact bridge so that one of said switching fingers engages said contact bridge thereby causing one of said contact elements to engage with an aligned one of said contacts on said housing; and means engaging with each of said elements extending from said housing for moving said operating lever to cause said other switching finger to engage said contact bridge whereby said contact bridge is rotated so that the other of said contact elements engages with a respective aligned one of said contacts on said housing.
Claim 2
Dependent Claim
229 words
A multiple contact switching apparatus, comprising: a non-conductive housing including a plurality of individual compartments, said housing including integral wiring paths terminating at fixed contacts, each of said compartments including fixed contacts connected to respective ones of said wiring paths, a support member, and an opening; a plurality of switching mechanisms each mounted respectively in one of said compartments, each of said switching mechanisms comprising, an operating lever mounted on said support member, said operating lever including spaced switching fingers and an element extending through said opening outside said housing; a contact bridge mounted on said operating lever and extending over said switching fingers, said contact bridge including spaced contact elements aligned with corresponding contacts on said housing, support means extending from said contact bridge and in contact with said housing; means interconnecting said operating lever and said contact bridge for biasing said contact bridge so that one of said switching fingers engages said contact bridge thereby causing one of said contact elements to engage with an aligned one of said contacts on said housing; and means engaging with each of said elements extending from said housing for moving said operating lever to cause said other switching finger to engage said contact bridge whereby said contact bridge is rotated so that the other of said contact elements engages with a respective aligned one of said contacts on said housing.
Claim 3
Dependent Claim
39 words
A multiple contact switching apparatus as in claim 1 wherein said operating lever has a U-shaped cross section and said contact bridge is mounted within the arms of said operating lever by a projection engaging with said operating lever.
Claim 4
Dependent Claim
18 words
A multiple contact switching apparatus as in claim 2 wherein said contact bridge consists of a blade-like element.
Claim 5
Dependent Claim
25 words
A multiple contact switching apparatus as in claim 1 wherein said operating lever is bent to be in contact with each of said switching fingers.
Claim 6
Dependent Claim
46 words
A multiple contact switching apparatus as in claim 1 wherein each of said switching mechanisms further comprises an additional contact bridge mounted on said operating lever by an additional biasing means and said additional contact bridge includes an additional support means in contact with said housing.
Claim 7
Dependent Claim
31 words
A multiple contact switching apparAtus as in claim 5 wherein each of said compartments includes a projection and one end of said additional contact bridge is pivotally connected to said projection.
Claim 8
Dependent Claim
66 words
A multiple contact switching apparatus as in claim 5 wherein each of said switching fingers is in the form of a supporting arm having a respective opening through which said contact bridge and said additional contact bridge respectively protrude whereby upon rotation of said operating lever said contact bridge and said additional contact bridge are slightly shifted to cause a wiping action of the contact elements.
Claim 9
Dependent Claim
43 words
A multiple contact switching apparatus as in claim 5 wherein said operating lever has a U-shaped cross section and said contact bridge and said additional contact bridge are mounted within the arms of said operating lever by projections engaging with said operating lever.
Claim 10
Dependent Claim
34 words
A multiple contact switching apparatus as in claim 1 wherein one side of said housing extends beyond an adjacent wall thereof and includes said fixed contacts at the end portion of said extended side.
Claim 11
Dependent Claim
190 words
A multiple contact switching apparatus, comprising: a non-conductive housing including a plurality of individual compartments, said housing including integral wiring paths terminating at fixed contacts, each of said compartments including fixed contacts connected to respective ones of said wiring paths, a support member, and an opening; a plurality of switching mechanisms each mounted respectively in one of said compartments, each of said switching mechanisms comprising, a contact bridge including spaced contact elements aligned with corresponding contacts on said housing, support means extending from said contact bridge and in contact with said housing, one end of said contact bridge is pivotally engaged with said housing and the other end of said contact bridge extends through said opening; means interconnecting said contact bridge and said housing for biasing said contact bridge so that one of said contact elements is in contact with an aligned fixed contact on said housing; and means engaging with each of said elements extending from said housing for moving said contact bridge whereby said contact bridge is rotated so that the other of said contact elements engages with a respective aligned one of said contacts on said housing.
Claim 12
Dependent Claim
190 words
A multiple contact switching apparatus, comprising: a non-conductive housing including a plurality of individual compartments, said housing including integral wiring paths terminating at fixed contacts, each of said compartments including fixed contacts connected to respective ones of said wiring paths, a support member, and an opening; a plurality of switching mechanisms each mounted respectively in one of said compartments, each of said switching mechanisms comprising, a contact bridge including spaced contact elements aligned with corresponding contacts on said housing, support means extending from said contact bridge and in contact with said housing, one end of said contact bridge is pivotally engaged with said housing and the other end of said contact bridge extends through said opening; means interconnecting said contact bridge and said housing for biasing said contact bridge so that one of said contact elements is in contact with an aligned fixed contact on said housing; and means engaging with each of said elements extending from said housing for moving said contact bridge whereby said contact bridge is rotated so that the other of said contact elements engages with a respective aligned one of said contacts on said housing.
