The invention relates to a brush system (3) for an electric actuator (1), to an electric actuator (1) having such a brush system (3) and to a method for assembling an electric actuator (1). The aim of the invention is to simplify assembly of a brush system (3). For this purpose, the brush system (3) is characterized by at least one mechanical contact element (33) for providing an external interface. Said external interface electrically connects the brush system (3) to a connecting element (4) outside the brush system (3), for example a printed circuit. Provision of the external interface on the brush system (3) allows to assemble the electric actuator (1) in separate assembly steps.
