Abstract
An electromagnetic relay includes a coil member having flanges and an angular yoke and a flat armature seated in front of a free end of the yoke. A terminal angle is secured to a leg of the yoke and serves for bearing the armature and for connection of a contact spring connected to the armature. During assembly, the armature assembly composed of the armature, the terminal angle and the leaf spring is preassembled and joined to the coil assembly. Afterwards, the entire magnetic system assembly is placed into a pedestal assembly which includes terminal elements and plug shafts for the coil terminals as well as cooperating contact elements. The plug shafts in the pedestal can be optionally equipped with different cooperating contact elements.
