A power cord on an appliance terminates in a (male) plug; it connects to a (female) socket in a wall or on an extension cord. Coaxial cables used for video or other high-frequency signals are normally terminated, at both ends, in a connector comprising an inner pin and an outer fixed or rotating shell; these are conventionally reckoned as male.
Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By correctly connecting two of these switches together, toggling either switch changes the state of the load from off to on, or vice versa. The switches may be arranged so that they are in the same orientation for off, and contrasting orientations for on. [1]
Power On (IEC 60417-5007) and Power Off (IEC 60417-5008) symbols are used to indicate positions of the rocker switch Power button marked with Standby symbol (IEC 60417-5009) turns the device on or off without fully disconnecting power supply.

Extension cords (extension leads) are used for temporary connections when a socket is not within convenient reach of an appliance's power lead. This may be in the form of a single socket on a flexible cable or a power strip with multiple sockets. A power strip may also have switches, surge voltage protection, or overcurrent protection.
Medium-voltage circuit breakers may be connected into the circuit by bolted connections to bus bars or wires, especially in outdoor switchyards. Medium-voltage circuit breakers in switchgear line-ups are often built with draw-out construction, allowing breaker removal without disturbing power circuit connections, using a motor-operated or hand ...
Switches that turn the power off when the connected device goes into standby, [30] or that turn other outlets on or off when a device is turned on or off are also available. Switches can be activated by sensors. Home automation sensors, switches and controllers can be used to handle more complex sensing and switching. This produces a net saving ...
