Abstract:

To provide an electromagnetic relay capable of carrying out a falling-off prevention measure of a card.

In the electromagnetic relay 1 in which since movable contact terminals 22, 32 are locked to a card 8 slide-displaced by an armature 6 driven by an electromagnet block 5, the terminals 22, 32 are curved and deformed, and a contact point state is switched by being contacted with or separated from fixed contact terminals 21, 31, the displacement of the card 8 is regulated in the slide direction 82 by both sidewalls 42, 43 of a body 4. In the case a tongue piece 65 of the armature is engaged with one end side and the movable contact terminals 22, 32 are locked to the other end side, in the card 8, a protrusion 80a extending toward both sidewalls 42, 43 are formed on its one end side, and in both sidewalls 42, 43, guide grooves 42a, 43a which extend in the slide direction 82 and into which the protrusion 80a fits are formed. Accordingly, even in a constitution of fewer contact points, the falling-off prevention can be carried out surely.
