Control Elect Pdf For Free

A switch is the most common circuit control device. Switches normally have two or more sets of contacts. Opening these contacts is called ?break? or ?open? the circuit, closing the circuit is called ?make? or ?completing? the circuit.

An electric fuse is a safety device, which is used to limit the current in an electric circuit. The use of fuse safeguards the circuit and appliances connected in that circuit from being damaged.

An electric switch is an electrical component that breaks or closes an electric circuit. Opening the switch (breaking the circuit) means turning off the electrical device and closing the switch (completing the circuit) allows an electrical current to flow so that the device is on.

The device that controls electric current is called a "current controller" or "current regulator." It is a crucial component in various electrical systems and circuits, enabling the management and regulation of the flow of electric current.

Pilot lights, relays, and contactors are examples of control loads. Control devices are used to activate the control load. Pushbuttons and switches are examples of control devices.

There are three type of common circuit control devices; switches, relays and solenoids. Switches, in simple terms is a two piece metal called contacts that touch to make a circuit and separate to break the circuit. Switches can be classified ing to the arrangement of their contacts.

The Control Circuit often operates at a lower voltage than the Power Circuit for safety and ease of installation. A device that controls the flow of electrical power to a motor. It is designed to safely start and stop a motor, and provide overload protection.
