Contactor Interlocking Wiring:

This diagram shows how to make contactor interlocking wiring. In this circuit diagram. We use a total of 2 magnetic contactors, a stop switch, a forward switch, and a reverse push switch. This diagram is very easy to connect. If you want to see how to connect the circuit please check our youtube video link in the below post. Please be sure you have good knowledge about electricity otherwise any mistake can be a hazard to your life.

Components used to make the Contactor Interlocking Wiring:

01. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

02. Push Switch:

In industry the switch connected to the magnetic contactor of the motor controlling circuit is manually/pushed by the operator and has elasticity i.e. can return to its original position by means of a spring when released is called a pushbutton switch. Push-button switches are used with electric motor starters, with calling bells, and sometimes as temporary supplies in lamp circuits. When the pushbutton switch is pushed and released, the control circuit is de-energized when it returns to its original position. So latching is done to hold the power.
