Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contactors for switching and with separate compartments for power switching and control.

By means of a light intensity sensor ( photoresistor, photodiode, phototransistor, etc.) that detects the amount of light that illuminates an environment, it triggers an electrical circuit that opens or closes the contacts of a mechanical relay or of a solid state relay. (power transistor, thyristor, triac, etc.), which activates the lighting ...
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 between the switches. When the load is controlled from only two points, single pole, double throw (SPDT) switches are used.
Shown here will be fastened to this recessed, non-metallic box, then a cover plate is installed. This "double gang" (two unit) installation uses non-metallic-sheathed cable and twist-on wire connectors. In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical ...
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.
An electromagnetic relay with a pair of contacts. An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. [1]
A lighting control console (also called a lightboard, lighting board, or lighting desk) is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth .
A lighting control system is intelligent network-based lighting control that incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and ...
