Zusammenfassung:A manually operable, three-pole disconnect switch has a contact structure for each pole that comprises a line-side contact module and a load-side contact module that carry the stationary contacts for that pole, these contacts being vertically spaced and positioned for engagement by one of three movable contact assemblies carried on a horizontally disposed, pivotable crossbar. Each line-side contact module extends upwardly from the crossbar and each load-side contact module extends downwardly from the crossbar and its corresponding line-side contact module. The line-side contact module has two integrally formed housing parts and a bar-shaped conductor that is sandwiched therebetween and positioned in a substantially vertical plane. The housing forms both an insulating base and an insulating portion of an arc chute which partially encloses the conductor that forms a stationary contact within a housing cavity. The line-side module is supported upon a pedestal of its corresponding load-side module, this pedestal having a slot which receives the stationary contact portion of the conductor to provide a tongue-in-groove coupling between the two modules.
