A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room. In contrast to a simple light switch , which is a single pole, single throw (SPST) switch, multiway switching uses switches with one or more additional contacts and two or more wires are run ...
For street lighting, for example, an individual twilight switch can be used, or a central switch that activates the other remote relays to turn on many lamps, so that the load that the central twilight switch must withstand is only of the individual coils of the relays in parallel.
AC contactor for pump application. A contactor is an electrically controlled switch used for switching an electrical power circuit. [1] A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
In larger lighting systems, for example warehouses or outdoor lighting systems, the required current may be too high for a manual switch. In these systems light switches control lighting contactors, a relay that allows the manual light switch to operate on a lower current, with smaller wiring than would be required in the main lighting circuit.
A motor control center (MCC) is an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter , fuses or circuit breaker , and power disconnect .

A solid-state contactor is a heavy-duty solid state relay, including the necessary heat sink, used where frequent on-off cycles are required, such as with electric heaters, small electric motors, and lighting loads. There are no moving parts to wear out and there is no contact bounce due to vibration.
The term lighting control system refers to an intelligent networked system of devices related to lighting control. These devices may include relays, occupancy sensors, photocells, light control switches or touchscreens, and signals from other building systems (such as fire alarm or HVAC). Adjustment of the system occurs both at device locations ...
Contacts may be operated by humans in push-buttons and switches, by mechanical pressure in sensors or machine cams, and electromechanically in relays. The surfaces where contacts touch are usually composed of metals such as silver or gold alloys [ 3 ] [ 4 ] that have high electrical conductivity , wear resistance, oxidation resistance and other ...
