ABSTRACT:
An electromagnetic relay is provided which is small in size and is capable of controlling two circuits of an ordinarily-open contact, which has a large current-carrying capacity and high interrupting capability, and which is excellent in resistance against shock and vibration. Movable contactors are held, through bow-shaped movable contactor springs, to two-shaped holding frames each being electrically separated and being mechanically connected via a card made of a highly heat-resistant resin in a card block. Thick-plate shaped movable contacts, which are attached to the movable contactors in a fixed manner, are electrically connected or disconnected to fixed contacts in a base block, in synchronization with operations of an armature of an electro-magnet block. In order to improve a current-carrying capability and interrupting capability, there are provided two pieces of ordinarily-open contacts which are connected in series to each other, and between which an interval is doubled, in each of two circuits.
