Abstract
An electromagnetic relay has three fixed contact terminal assemblies arrayed in a row at regular intervals, and a movable contact spring assembly having three movable contacts. An armature is caused to swing by turning on and off an exciting current to a coil assembly so that normally-open contact portions are closed and opened. A movable spring of the movable contact spring assembly is branched into three portions on one end side thereof and a substantially U-shaped slit is formed in each of the branched portions so that spring flexible portions and a current-carrying path portion are separately formed in each branched portion. A current-carrying plate is joined to the three current-carrying path portions so that the three movable contacts are electrically connected together.
