Abstract
An electromagnetic relay, comprising: an electromagnetic coil; an iron core passed centrally through the electromagnetic core; a yoke having a first end connected to a first end of the iron core; and an L-shaped armature, having a short piece and a long piece connected to each other via a corner portion, pivotally supported by a second end of the yoke at its corner portion so that the short piece may move toward a second end of the iron core by magnetic attraction when the electromagnetic coil is energized and move away from the second end of the iron core by a spring force of spring means when the electromagnetic coil is de-energized. The second end of the yoke may be provided with a part having a locally enlarged cross section to reduce the magnetic resistance at the interface between the armature and the yoke. The short piece of the armature may be provided with a projection near the corner portion which slides along a fixed surface in order to keep the armature resting upon the yoke in a stable fashion.
