A
solid state multi-pole switching device has input terminals for a plurality (n) of
input control circuits, output terminals for a plurality (m) of output circuits each having an associated
solid-state switch unit for switching a respective
external circuit load, and a field-programmable unit coupled between the n
input control circuits and the m output circuits for selectively establishing an
electrical connection of any
input control signal to any selected output circuit. The device components are carried on a main circuit board, with the
solid state switch units (Triacs) mounted on plug-in boards selectively installed in an array of sockets on the main circuit board. The field-programmable unit may be a simple pin-and-
jumper array, or a CPU coupled to an LCD display and settings control device.
Timer controls may be programmed through the CPU for automatic on / off switching without the need to manually activate the input control circuits. The device allows a field installer or user to program the desired input / output switching connections onsite, with output circuits being grouped and controlled by input control signals in any desired combination. The device can be used in a wide range of multi-
circuit switching control applications such as commercial, industrial or home lighting applications including, but not limited to, stadium lighting, office space lighting, industrial
plant lighting, school lighting, home interior or exterior lighting, or store lighting and display.
