Switch for reversing the direction of an electric current
In mathematics, the commutator gives an indication of the extent to which a certain binary operation fails to be commutative. There are different definitions used in group theory and ring theory.
A plugboard, or control panel (the term used depended on the application area), is an array of jacks, or hubs, into which patch cords can be inserted to complete an electrical circuit. Control panels were used to direct the operation of some unit record equipment. ...
A commutator is a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit. ...

(Commutators) are an intermediate concept. Commutators work sort of like algorithms, but they are much more versatile, and can generally be applied to many different situations, as opposed to an algorithm which is specific to only one case. ...
The part of a DC motor armature that causes the electrical current to be switched to various armature windings. Properly sequenced switching creates the motor torque. ...
