Electro-magnetic relay having two armatures |
摘要 |
A relay includes two armatures each having a contact spring and a contact piece secured thereto which interacts with the respective cooperating contact element. The two movable contact pieces are electrically connected by a stranded copper conductor so that a series connection of the two contacts is formed. The series connection can be interrupted twice by the two armatures which switch independently of one another so that a reliable opening of the circuit is assured even if one of the contacts fuses. The relay is particularly useful for safety circuits such as in motor vehicles.
