Abstract
Carbon segments (7) of a planar commutator are molded over contact members (5). Anchor means (8), integral with each carbon segment (7) have an interlocking part (11) engaging the rear surface (6) of the contact member (5) and fit into a first blind hole (4) in the form of a recess of uniform transverse cross-section extending rearwardly of the front end (3) of a molded plastic base member (1). The contact members (5) are each attached to the base member (1) by means of locking portions (15) which project into second blind holes (14) having internal surfaces which grip the locking portions (15).
