Abstract
In an M.B.B. type relay, a contact spring comprises a pair of flat spring parts integral at the base of the spring and separate at their free ends, each of which cooperates with a fixed contact. An actuating card drives both spring parts in the same direction and has a stepped portion so dimensioned that a first contact formed by one of the spring parts with one of the fixed contacts is closed before the second contact formed by the other spring part with the other fixed contact is opened.
