Electrical appliance interlock switch with improved buss

Claim 2

An interlock switch, comprising: a housing having an interior front wall; first conductive switch means mounted in said housing along said wall; second conductive switch means mounted in said housing adjacent to said first switch means and along said wall; third conductive switch means mounted in said housing adjacent to said second switch means and along said wall, so that said second switch means is disposed between said first and third switch means; a first insulating barrier mounted in said housing between said first and said second conductive switch means, said first insulating barrier having a forward portion displaced from said front wall and defining a first gap therewith; a second insulating barrier mounted in said housing between said second and said third conductive switch means, said second insulating barrier having a forward portion displaced from said front wall, and defining a second gap therewith; and an electrically conducting buss, disposed within said first gap and said second gap, and electrically interconnecting said first conductive switch means and said third conductive switch means across said second conductive switch means without contacting said second conductive switch means.

Claim 3

The interlock switch defined in claim 1 wherein said buss is disposed edgewise within said first and second gaps and is captivated therein.

Claim 4

The interlock switch defined in claim 1 wherein said first conductive switch means includes at least one conductive switching blade and said second conductive switch means includes at least one other conductive switching blade, said buss including an intermediate conducting portion conductively connected to said blades at its ends.

Claim 5

The interlock switch defined in claim 3, wherein said buss is integrally formed with said blades.

Claim 6

An interlock switch, comprising: a housing having a front wall; a plurality of conductive switch elements mounted in said housing for making and breaking electrical switching connections, said plurality including one or more first contactor elements, one or more second contactor elements located adjacent to said first contactor elements, and one or more intermediate contactor elements located between said first and second contactor elements; barrier means including first and second insulating barrier walls disposed in said housing and forming a plurality of compartments which isolate said first from said second contactor elements, and said intermediate contactor elements from said first and said barrier walls having ends disposed in spaced relation to said front wall and an electrically conducting buss disposed in upstanding relation within the space defined between the ends of said barrier walls and said front wall and electrically interconnecting at least one of said first contactor elements and at least one of said second contactor elements across said barrier walls and across said intermediate contactor elements without conductively contacting any of said intermediate contactor elements and without interferring with the isolation of said compartments.

Claim 7

An interlock switch, comprising: a housing having a front wall; a plurality of conductive switch elements mounted in said housing for making and breaking electrical switching connections, said plurality including one or more first contactor elements, one or more second contactor elements located adjacent to said first contactor elements, and one or more intermediate contactor elements located between said first and second contactor elements; barrier means including first and second insulating barrier walls disposed in said housing and forming a plurality of compartments which isolate said first from said second contactor elements, and said intermediate contactor elements from said first and said barrier walls having ends disposed in spaced relation to said front wall and an electrically conducting buss disposed in upstanding relation within the space defined between the ends of said barrier walls and said front wall and electrically interconnecting at least one of said first contactor elements and at least one of said second contactor elements across said barrier walls and across said intermediate contactor elements without conductively contacting any of said intermediate contactor elements and without interferring with the isolation of said compartments.

Claim 8

The interlock switch defined in claim 5 wherein said buss comprises a first segment integrally formed from at least one of said first contactor elements, and a second segment integrally formed from at least one of said second contactor elements.
