Abstract
A relay includes a contact spring which closes or interrupts an electric circuit between a first and a second relay contact. One end of the contact spring is conductively connected to the first relay contact and another free end of the contact spring closes or interrupts the electric circuit in a first end position of the contact spring and in a second end position of the contact spring, respectively. An armature is provided which can be adjusted by a reversible magnetic field for deflecting the contact spring into the respective end position. An additional spring is provided for biasing the contact spring into the first end position, wherein the additional spring is supported, at least in the first end position, on the armature or on an actuator of the armature.
