Abstract
A magnetically actuatable contactor has first and second magnetic material strips extending longitudinally. Each has a pad with a contact face parallel to the longitudinal direction. The pads face each other when an intersection of the one contact face and a projection in a transversal direction of the other contact face forms an overlap zone having a surface area. A pad is capable of being transversally shifted in response to a magnetic field between closed and opened positions. In closed position and open positions, the faces and respectively in contact and separated. At least one strip forms pairs of facing pads disposed consecutively along the longitudinal direction. A bridge links two consecutive pads. A cross-section of the bridge is reduced relative to a cross-section of the pads and a surface area of a smallest cross-section of the bridge.
