Abstract
A divisional excitation type coordinate switching device featuring a single magnetic shunt plate and preformed elongate excitation coils arranged on the top and bottom sides thereof and each surrounding a row or column of switching elements. Terminal blocks are secured to the four sides of the shunt plate, enabling arrangement of component parts in a fully developed formation. Outstanding among the advantages gained are substantial reduction in winding cost and overall size, ease of assembling and improved operational reliability.
