Contactors

A contactor is an electromechanical device that is used to control the flow of electricity in a circuit. A contactor typically consists of a coil, a set of contacts, and an armature. When the coil is energized, the armature is magnetically attracted to the contacts, closing the circuit and allowing electricity to flow. When the coil is de-energized, the armature is released, opening the circuit and stopping the flow of electricity. Contactors are commonly used in industrial and commercial applications to control motors, lighting, and other electrical loads. They are often used in conjunction with control circuits, such as timer relays and programmable logic controllers (PLCs), to automate the control of electrical circuits.
