What is needed

A remote switch or contactor is an electrical device used to control and manage the power supply of an electrical circuit. It is a rugged, solid, and usually solid-state device that can be used to power electrical equipment and machines. The remote switch or contactor is a power switch that can handle high currents and even very high voltages.

How it works

A contactor or contactor is made up of a series of contacts that open and close when electricity is applied to it. The contacts can be opened or closed based on the signal being sent from an external source. The remote breaker or contactor can be activated by an external source, such as a relay, timer, or sensor, or it can be activated manually via a push button switch. When the contacts close, electricity can flow through the circuit powering connected equipment or machines.

Applications

A contactor or contactor is an essential component for many industrial and commercial applications. It is used to operate equipment, electric machines, machine tools, industrial machinery, lighting systems, heating systems and more. It is also used in many security systems to shut off power in the event of an alarm or emergency. In addition, contactors or contactors are often used in industrial automation systems to control a wide range of processes.
