Commutator: meaning, definitions and examples

Used in electrical engineering to refer to a device that periodically reverses the direction of current between the rotor and the external circuit in electric motors and generators.

• The engineer inspected the commutator for wear and tear.
• The motor's commutator was sparking, indicating a need for maintenance.

A general term for a device used to break or connect an electrical circuit, it can refer to any type of switch, from a simple light switch to complex circuit breakers.

• Flip the switch to turn on the light.
• The main power switch is located on the back of the equipment.

Utilized when a switch needs to have multiple positions or settings, often in devices like radios, ovens, or even industrial machinery.

• The rotary switch on the oven allows you to select different cooking functions.
• By turning the rotary switch, you can cycle through the various modes of the device.

Commonly used in contexts where it’s necessary to change the direction of an electric current or mechanical movement, such as in motors or some control systems.

• The reversing switch allowed the conveyor belt to move in the opposite direction.
• Ensure the reversing switch is set correctly before starting the machine.
