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.

An electromagnetic relay, comprising:
- a coil member carrying a winding and having an axis extending parallel to a terminal plane of said relay, said coil member including coil flanges:
- winding supporting wires secured in said coil flanges;
- a core extending into said coil member in a direction of said axis;
- an angular yoke having a first leg coupled to an end of said core, said angular yoke having a second leg extending parallel to said axis and adjacent said winding;
- a flat armature seated on a free end of said second leg of said angular yoke, said flat armature forming a working air gap with a free end of said core;
- a leaf spring having a restoring leg biasing said flat armature relative to said angular yoke, said leaf spring having at least one contact spring leg;
- at least one cooperating contact element cooperating with said at least one contact spring leg;
- a separately manufactured pedestal having said coil member arranged thereon, said pedestal having a plurality of optionally equippable plug shafts for different types of cooperating contact elements;
- terminal elements for said coil member and for said contact elements being fixed in said pedestal;
- said winding supporting wires being at an underside of said coil member and being connected to appertaining ones of said terminal elements and;
- a separately fabricated terminal angle connected to said leaf spring in electrically conductive fashion and being secured to said second leg of said angled yoke,
- said terminal angle having a first section lying flat on said second leg of said angular yoke,
- said terminal angle having a second section bent at a substantially right angle relative to said first section, said second section surrounding an end of said flat armature that is seated on said angular yoke,
- said terminal element having a third section extending relative to an underside of said relay and forming a terminal element for said leaf spring.
