[electric] A commutator is the moving part of a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverse the current direction between the rotor and the external circuit. Commutators have two or more softer metallic brushes in contact with them to complete the other half of the switch. ...

Device in a DC (direct-current) electric motor that reverses the current flowing in the armature coils as the armature rotates. A DC generator, or dynamo, uses a commutator to convert the AC (alternating current) generated in the armature coils into DC. A commutator consists of opposite pairs of conductors insulated from one another, and contac...
