    摘要： Two molded case electrical switches (3a,3b) such as circuit breakers, network protectors, disconnect switches and transfer switches, are secured together side-by-side by joining blocks (21) having tongues (27,29) extending along their sidewalls (23) which engage undercutting grooves (13,17) undercutting the irregular surfaces (11a,11b) of the confronting sidewalls (9a,9b) of the switch molded casings with an interference fit. Separate joining blocks (21f,21r) for the front (5f) and rear sections (5r) of the molded casing are driven into place and retained by bolts (45) engaging flanges (49a-49b) on the molded casing. The poles (7) are paralleled by external conductors (61,63) in any desired configuration so that the standard switches (3a,3b) can be used without customization.
