contactors are electrically-controlled switches used for switching an electrical power circuit. A contactor is typically controlled by a circuit that has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
A contactor is an electrical device that is used for switching an electrical circuit on or off. It is considered to be a special type of relay.
There are different types of contacts in a contactor, and they are; auxiliary contact, power contact, and contact spring.
