ABSTRACT:
A switch assembly adapted especially for use in a pivotal hookswitch mechanism which includes a transverse camshaft acting as a contact operating shaft for a plurality of transversely spaced contact spring operating pairs, each pair having a contact spring in a first and second spaced apart alignment. A housing encloses the shaft and contact springs. The contact springs are leaf springs resting in two parallel arrays of slots in the housing, the springs being identical. The housing is formed of two identical shell members each forming a half of the housing with one half being inverted relative to the other to form the central cavity for the operating components of the mechanism. An insert between spring arrays forces formed sections of the springs of an alignment into insulation piercing engagements with insulated wires during the assembly of the insert to the two housing sections.
