Electrical relay

1. An electrical relay, comprising:

a magnetic system including an armature;

a contact system including a moveable spring contact and a fixed spring contact, the moveable spring contact being moveable between an open position and a closed position, the moveable spring contact being in electrical contact with the fixed spring contact in the closed position; and

a slider connecting the moveable spring contact to the armature, the slider transferring movement of the armature to the moveable spring contact, the slider having at least one contact opening element extending there from, the contact opening element striking the moveable spring contact during movement of the moveable spring contact to the open position to break any existing weld between the moveable spring contact and the fixed spring contact;

wherein at least one of the contact opening elements extends toward the fixed spring contact and wrappingly engages an end face of the moveable spring contact that faces the fixed spring contact, the contact opening element strikes the moveable spring contact after being pulled a distance by the slider.

2. The electrical relay of claim 1 , wherein the electrical relay is monostable.

3. The electrical relay of claim 1 , wherein the electrical relay is bistable.

4. The electrical relay of claim 1 , wherein the contact opening element is shaped substantially as a hook.

5. The electrical relay of claim 1 , wherein the contact opening is received in and guided by a recess in the moveable spring contact.

6. The electrical relay of claim 1 , wherein the slider is moveable substantially parallel to a base plane of a base of the electrical relay and the moveable spring contact and the fixed spring contact extend substantially perpendicular to the base plane of the base of the electrical relay.

7. The electrical relay of claim 1 , wherein the moveable spring contact is arranged between the fixed spring contact and the slider.

8. The electrical relay of claim 1 , wherein the contact opening element includes a shoulder that engages the moveable spring contact during movement of the moveable spring contact to the closed position.

9. The electrical relay of claim 1 , wherein the armature includes an armature projection that engages in an armature projection receiving recess formed in the slider.

10. The electrical relay of claim 1 , wherein the armature pivots between a first switching position and a second switching position.

11. The electrical relay of claim 1 , wherein the armature includes armature plates separated by a permanent magnet.

12. The electrical relay of claim 1 , wherein the contact opening element strikes the moveable spring contact immediately before the moveable spring contact reaches the open position.

13. The electrical relay of claim 1 , wherein the contact opening element is shaped substantially as a hook.

14. An electrical relay, comprising:

a magnetic system including an armature;

a contact system including a moveable spring contact and a fixed spring contact, the moveable spring contact being moveable between an open position and a closed position, the moveable spring contact being in electrical contact with the fixed spring contact in the closed position; and

a slider connecting the moveable spring contact to the armature, the slider transferring movement of the armature to the moveable spring contact, the slider having at least one contact opening element extending therefrom, the contact opening element striking the moveable spring contact during movement of the moveable spring contact to the open position to break any existing weld between the moveable spring contact and the fixed spring contact;

wherein at least one of the contact opening elements extends toward the fixed spring contact and wrappingly engages an end face of the moveable spring contact that faces the fixed spring contact, the contact opening element strikes the moveable spring contact just before the slider is fully opened.
