Gollub (1960) described how electromechanical appa- ratus can be made more versatile with multiple-bank rotary switches, which allow the experimenter to change the connections in a given array of equipment simply by dialing the appropriate circuits.Another device that permits multiple connections is the matrix or cross-bar switch, originally designed for electrical operation in
