Abstract (en)
[origin: EP2565890A1] The device has a central moving contact (5A) and lateral moving contacts (5B, 5C) associated with a pair of fixed contacts, where the moving contacts are parallel and offset in space with respect to each other to stagger in time approach of the moving contacts on the fixed contacts when closing an electrical circuit. The central moving contact is arranged ahead of the lateral moving contacts so that the central moving contact is the first to establish current when closing the electrical circuit and the last to interrupt current when opening the circuit.
