What are Contactors in Electric Switches?

Contactors are a type of electric switch, are made for handling heavy loads in circuits Contactors are made for operating and controlling heavy loads in industrial applications. They are large and heavy than regular standard switches and are more robust than standard electric switches. They are widely used in controlling motors, transformers, and other high-power devices. Contactors have multiple sets of contacts and have main contacts used for carrying the load current and auxiliary contacts for control and feedback purposes.

Electric Switch

An electric switch is an important component in an electrical circuit. An electric switch is a simple device that either breaks the circuit or completes it to stop or start the flow of current. An electric switch is an arrangement to switch the circuit ON and OFF as needed. It is also called a “Key” component in an electrical circuit. Basically, it is used to interrupt the general flow of electrons. In this article we will learn about Electric switches, the Working of electric switches, the construction of electric switches and different types of electric switches, and advantages and disadvantages, and their applications.

What is an Electric Switch?

An electric switch is an electromechanical device that connects or disconnects the electricity supply to a circuit. Electric switches are very important in electrical circuits because, without an electric switch, all the devices we are using are useless and cannot be operated without a switch. Electric switches can be used to connect and break the flow of connectivity in the circuit. Electronic switches can be used to perform all logical functions in the circuit. It is used to open close the circuit. So, the flow electrons totally depend on this, whether it will enable it or disable it. It does respond to the force, or we can say, external force so that electrical signal can be changes...

Working of an Electric Switch

A electrical switch are basically on/off toggle ones. Electric switch responds to an external force to mechanically change an electric signal. Electric switches are used to turn electric circuits ON and OFF and to switch electric circuits. The main function of an electric switch is to regulate the current between the load and source of power. The power source is the electrons that push through the circuits. The voltage is the quantity of force or pressure applied by the power source. Electrical switches work according to a basic design. Electric switches control the amount of electricity passes on the circuit and passes the required power to electrical appliances as required....

Electric Switch Loads

An electrical switch is a device that allows or stops the flow of electrical electricity by opening or closing a circuit. The appliances or electrical equipment that a switch regulates are known as loads when they are attached to a switch. Switch loads refer to the electrical equipment or devices that a switch controls. Switches are used to open or close the flow of current to the associated load by opening or closing an electrical circuit. Lights, motors, heaters, fans, and other electrical appliances are some examples of common switch loads....

Why do We Need Electric Switch?

We need electric switch to operate any electrical gadgets in our home or anywhere. Without electric switch the gadgets we use in our daily life becomes useless. Without electric switch operating the gadgets become difficult. An electric switch is used to complete or break an electric circuit in order to use any electric appliance. When an electric switch is in the ON position, it completes the circuit and allows current to flow through. if the electrical switch is in the OFF position when it breaks the circuit and prevents current from passing through. Electric lamps, coolers, washing machines, table fans, TVs, radios, and other electrical devices have built-in switches and can be operated using electrical switches....
