Electromagnetic relay
 An electromagnetic relay which is so arranged that a plate spring having a movable contact and a fixed contact plate having a fixed contact are secured to a stopper member fixed to a heel piece for the electromagnet, with a lift pin of the plate spring being adapted to contact the moving iron, so that the pressure at the contacts and the gap between the contacts as well as the lowest working voltage are readily adjusted as desired by merely transforming the stopper member. Furthermore, since the movable contact is free from positional deviation, mutual erosion or cutting between the contacts due to uneveness of the contact surfaces arising from sparks and the like has been eliminated for positive closing or opening of the contacts.
