Abstract

The system has at least two closure elements, further contact and actuator arrangement. Each closure element has its own actuator driven by a relay armature, the movable part of each closure element is positively coupled to the associated actuator in the contact opening direction and both actuators are positively coupled to the movable part of the further contact only in the direction towards the operating position. The system has at least two closure elements (10,20), a further contact (30) and an actuator arrangement with at least two parallel movable components that closes both closure elements and the further contact by moving a relay armature into its operating position and opens both closure elements by returning the armature to its rest position, but prevents restoration of the further contact if one closure element does not open. Each closure element has its own actuator (40,50) driven by the relay armature, the movable part of each closure element is positively coupled to the associated actuator in the contact opening direction and both actuators are positively coupled to the movable part (35) of the further contact only in the direction towards the operating position.
