Abstract
A leaf spring and contact arrangement for an electromagnetic switch. A movable contact has a magnetic body attached thereto and is restrained by side arms secured to a housing and bent arms connecting the contact member to the side arms. The side arms are arranged symmetrically about the center of gravity of the movable contact. The contact member, side arms and bent arms are all in substantially the same plane. A magnetic force overcoming the restraining force causes movement of the movable contact in a direction perpendicular to said plane. The leaf spring may be formed in a repeat pattern consisting of a plurality of movable contacts each having a pair of bent arms associated therewith for connecting the movable contact to the secured side arms.
