A programmable electrical switching system. The system is comprised of at least one addressable I/O node, a visual display, at least one button, and a control unit. The control unit is electrically connected to the visual display and the buttons, and responds to actuation of the buttons by transmitting information to the visual display for presentation to the operator and/or transmitting addressed commands to the I/O node. The I/O node controls the voltage and/or current supplied to a load connected to the I/O node in accordance with the commands received from the control portion. Instructions stored in a program portion of the control portion may be changed to change the functions of the electrical switching system. Thus, the buttons may perform a plurality of predetermined, programmable functions in accordance with the instructions.
