An electromagnetic relay apparatus, which is improved in miniaturization, performance, assembly accuracy, cost reduction, productivity, and reliability. A plurality of electromagnetic relays, each having an NO contact that is closed by applying exciting current to a coil and an NC contact that is closed when the excitation current is not passed through the coil, are arranged in line, one diagonally opposite to the next, on a base so that the respective NO/ NC contacts of adjacent electromagnetic relays are located in diagonally opposed positions in substantially point symmetrical relation. The electromagnetic relay includes an electromagnetic block having a couple of moving contacts, a first stationary contact and a second stationary contact both being connectable to external wiring, which are composed of uniform parts or components.
