Abstract
A relay is disclosed. In an embodiment a relay includes a first switching contact having a first main contact, a second main contact and a first movable contact; a second switching contact having a third main contact, a fourth main contact and a second movable contact, wherein the second switching contact is electrically isolated from the first switching contact; and an actuator configured to move both the first and second movable contacts from a first switching state into a second switching state by moving a drive element of the actuator from a first position into a second position.
Claims18
A relay comprising:
- a first switching contact having a first main contact, a second main contact and a first movable contact;
- a second switching contact having a third main contact, a fourth main contact and a second movable contact, wherein the second switching contact is electrically isolated from the first switching contact;
- and
- an actuator comprising a movable runner and a coil,
- wherein the runner comprises a drive element and a contact carrier coupled to the drive element and comprising a first arm, on which the first movable contact is arranged and a second arm on which the second movable contact is arranged,
- wherein the actuator is configured to move both the first and second movable contacts from a first switching state into a second switching state by moving the drive element from a first position into a second position,
- wherein, in a normal operating mode, the movable contacts and the main contacts are not permanently connected to one another,
- wherein, in the first switching state, the first movable contact is coupled in an electrically conductive manner between the first and second main contacts and the second movable contact is coupled in an electrically conductive manner between the third and fourth main contacts,
- wherein, in the second switching state, the first movable contact is electrically isolated from the first and second main contacts and the second movable contact is electrically isolated form the third and fourth main contacts,
- wherein the actuator is further configured to move one of the movable contacts from the first switching state into the second switching state by moving the drive element from the first position in a direction of the second position in an event of a fault in which one of the movable contacts is permanently connected to one of the main contacts, and
- wherein the runner and with it the first movable contact and the second movable contact is configured to perform, depending on the state of the coil, a translatory movement along a longitudinal axis of the coil between the first position and the second position.
