  4. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.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.

  5. Voltage controller - Wikipedia

    en.wikipedia.org/wiki/Voltage_controller

    A Voltage controller thyristor based dimmer rack An electrical schematic for a typical SCR-based light dimmer. A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency ...

    A number strip would be peeled out and wrapped around the wire near the end. Wire numbers were made up of a series of the number strips so wire 1051 would be four strips. There are also pocket sized printers that print onto an adhesive backed label that can be wrapped around the wire. The basic format for relay logic diagrams is as follows: 1.

  7. Motor controller - Wikipedia

    en.wikipedia.org/wiki/Motor_controller

    A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...

  8. Contactor - Wikipedia

    en.wikipedia.org/wiki/Contactor

    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.

  9. 0-10 V lighting control - Wikipedia

    en.wikipedia.org/wiki/0-10_V_lighting_control

    The controller reduces the returned volts to the light. If the controller returns the full 10 V, the light will be at its brightest level. The light will be at minimum level if no volts are returned. The current sinking scheme creates a fail safe situation. Should a control wire be cut or the controller fail, the lights will illuminate ...
