Name of tool: Switching Matrix
Creation date: circa 1966
Designer: Robert Kieronski
Robert Kieronski developed this instrument while working as a researcher at Western Electric, “as a means of generating general logic functions for automated testing.” (1)
The type of relay used – a wire spring relay – was not commonplace at the time, being primarily used in the telephone industry. The Switching Matrix was deployed by David Tudor in Bandoneon! (a combine)
to direct audio signals towards various outputs (lights, speakers) and other electronic instruments.
The Switching Matrix allowed different instruments to be connected to one another.
Summary of Materials
Frame, electronic components.
Sixteen wire spring relays, patchboard.
