Remote controlled multi purpose contactor are designed to provide reliable and cost effective solutions for a variety of applications. A contactor is essentially an electrically powered switch capable of switching electrical load currents. It can be used for controlling motors, lighting and other electrical loads.

The basic principle of a contactor is to allow the control of the AC mains with a relatively low current that can be switched on or off and controlled by an external signal. The contactor is connected to the AC mains voltage with a wire passing through a contact that is held closed by a mechanical spring which is powered by a small DC motor. When the remote signal is given, the DC motor moves the contact away from the AC mains allowing the AC current to pass through to the electrical load.

The most common types of contactors are single-phase, three-phase and variable speed contactors which are used to switch AC current for residential and commercial applications. Single phase contactors are used to switch lights, fans, pumps and other light loads. Three phase contactors are used to switch high load current in industrial and commercial applications. Variable speed contactors are used to regulate the speed of motors in different applications such as conveyors and mixing machines.

Multi purpose contactors can also be used for other applications like safety fuses, emergency light systems and signaling. They are available in different voltage and amperage ratings, depending on the particular application. They are also available in various sizes and styles and with many additional functional features.

Multi purpose contactors are generally considered to be very reliable devices and are commonly used in residential, commercial and industrial applications. They are highly efficient and are an excellent choice for controlling electrical loads in various applications.
