ABSTRACT:
An electromechanical timer includes a motor-driven cam, and electrical switches responsive to the cam supported in a housing. An array of rows and columns of electrical terminals are connected to the switches and extend from one end of the housing. First electrical busses of corrugated form fit into similarly shaped first channels parallel to each row of terminals and c-shaped second electrical busses fit into similarly shaped channels connecting the first channels and the terminals. The first and second busses are compressed between opposing walls of the first and second channels to provide a first bias force which holds the busses in place. The second busses are also compressed between their corresponding terminal and an opposing wall of the corresponding second channel to provide a second bias force in a direction perpendicular to the first bias force, which second bias force provides the force for electrically contacting the terminals.
