Abstract
An electromagnetic switch assembly having a structure adapted for integral formation of component parts and for reduction in size and production cost, including an insulating base plate having at least one through hole formed therein to serve as a cell for relay contacts. An integrated type switching device can be realized with a matrix array of such through holes and electromagnetic relays associated therewith, the relay contacts being mounted on the base plate through the medium of two groups of conductive layers formed on the opposite surfaces of the base plate and extending along the lines and rows of contact cells, respectively.
