Abstract
The present invention provides an electromagnetic relay that can achieve desired operation characteristics by simple and inexpensive construction even if it has a small thickness. Therefore, a movable iron pieceis rotated by excitation or non-excitation of an electromagnet, a movable contact pieceis elastically deformed through a card, and a movable contactopens and closes fixed contacts of fixed contact pieces. The movable iron pieceis provided with a card pressing portioncapable of pressing the card. The cardis provided with a contact piece pressing portioncapable of pressing the movable contact pieceby being rotated around a fulcrum. At least one of the movable iron piece and the card is provided with a press position changing portion, wherein when rotating the movable iron piece, force transmission from the movable iron pieceto the cardis performed at a position more distant from a press position by the card pressing portionof the iron piecewith respect to the fulcrum, and then performed by the card pressing portion
