commutator
Motor's electrical switch
A commutator is a rotating switch in electric motors and generators that reverses current direction at precise intervals, converting between alternating and direct current.
The segmented cylinder contacts brushes as it spins, maintaining continuous rotation.
In mathematics, a commutator measures how much two operations fail to commute—how far AB differs from BA.
