Abstract
In a relay (1) comprising a contact spring (4) which closes or interrupts the electric circuit between a first and a second relay contact (2, 3), one end of the contact spring being conductively connected to the first relay contact (2) and its other free end (5) closing or interrupting the electric circuit in a first end position of the contact spring (4) and in a second end position of the contact spring (4), respectively; an armature (10) which can be adjusted by a reversible magnetic field for deflecting the contact spring (4) into the respective end position; and an additional spring (16) biasing the contact spring (4) into the first end position, the additional spring (16) is supported, at least in the first end position, on the armature (10) or on an actuator (13;20) of the armature (10).
Claims12
Relay (1) comprising a contact spring (4) which closes or interrupts the electric circuit between a first and a second relay contact (2, 3), one end of the contact spring being conductively connected to the first relay contact (2) and its other free end (5) closing or interrupting the electric circuit in a first end position of the contact spring (4) and in a second end position of the contact spring (4), respectively;
- an armature (10) which can be adjusted by a reversible magnetic field for deflecting the contact spring (4) into the respective end position;
- and an additional spring (16) biasing the contact spring (4) into the first end position,
- characterized in that
- the additional spring (16) is supported, at least in the first end position, on the armature (10) or on an actuator (13;20) of the armature (10).
Relay according to any one of the preceding claims, characterized in that the additional spring (16) is formed as leaf spring.
Relay according to any one of the preceding claims, characterized in that the actuator (13;
- 20) is disposed such that it can be linearly displaced approximately in the direction of deflection (14) of the contact spring (4).
Relay according to any one of the preceding claims, characterized in that the actuator (13) is directly hinged to the armature (10).
