Sometimes it is handy to have an outlet controlled by a switch. Step by step instructions on how to wire a switched outlet.
This circuit is wired with a 2-wire cable running from the light to the switch location. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire. The white wire is marked black on both ends to identify it as hot. At SW1 it is connected to one of the terminals Wiring a light switch is very simple. The white (neutral) wire from the power source and the white (neutral) wire that goes to the light fixture get connected to each other. The black (hot) wires are what get connected to the light switch. Again, excuse my paint-covered hands
Run a two-conductor wire to a switch in a desired location and install electrical box with switch. Mark the extension wires with colored tape to identify switch wires (both ends).

Wait to connect the marked-black wire going to switch to hot (black) last Light switch wiring diagram depicted here shows the power from the circuit breaker panel going to a wall switch and then continues to a ceiling light with a three conductor cable. From the ceiling box an electrical receptacle outlet is fed power. The diagram above shows a two conductor cable from the circuit breaker panel going to a wall switch. If the switch is ON, the electric circuit is closed and the lamp glows, and if the switch is OFF, it will disconnect the power supply to the lamp. For safe operation this wiring is placed in a box called a switch box. The switch wire and live wire are a single wire; it is just cut in between to connect the switch I had added more pictures on how the wires connect to the bulb, battery and switch - 13/11batteryinsulated wirelight bulbducktapeon'off switchRead more here:..

A simple electrical circuit Once one of the wires is removed from the power source or a break is made in the flow, the circuit is now open and the lamp will no longer light. In practical application, circuits are opened by such devices as switches, fuses, and circuit breakers When you rotate the paperclip and make contact with the second thumbtack you close and complete the circuit, current flows through the circuit and lights up the bulb (Figure 3). The switch, bulb holder, and portable power pack are a complete circuit and arrangement of conductors; they allow the passage of electric current through the wire This is a simple light switch circuit where the wires are treated as transmission lines. When you hit the switch, it takes a while for the light and the source to get the message. Of course, in real life, it takes more than a nanosecond to flip a switch. Next: Memristor.

Repeat the process with the white wire, wrapping it clockwise around the other brass screw and tightening it with a screwdriver. Photo By: Jalynn Baker 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 By using this type of resistor to bias a transistor, we can make a transistor switch power to a load depending upon the light conditions. Simple transistor circuits with LDR are very common and utilised in night lighting and emergency lighting systems.
