Diagram of one way switch

Before go in details, we have to show the basic construction and operating mechanism of single way switch which is shown in fig below:. This is just like a series circuit i. Just connect the Neutral wire directly to the light bulb and then connect the light bulb to the switch through middle wire.

L and N indicate the supply. Switches are shown as dotted rectangles. Earth wires are not shown. Single switch. The most basic circuit, with only two wires at the switch.

.

To switch on the bulb, switch S 1 must be closed to complete the circuit and glow the light bulb.

Check permit requirements before beginning electrical work. How to read these diagrams. This page contains wiring diagrams for household light switches and includes: a switch loop, single-pole switches, light dimmer, and a few choices for wiring a outlet switch combo device. Also included are wiring arrangements for multiple light fixtures controlled by one switch, two switches in one box, and a split receptacle controlled by two switches, plus more. When the electrical source originates at a light fixture and is controlled from a remote location, a switch loop is used. 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.

One black wire comes from the power source the electrical panel and the other goes to one or more light fixtures. When the switch is on, electricity flows through it from the inbound wire to the outbound wire. When you turn the switch off, it interrupts the flow of electricity. The wiring diagrams on this page show how to wire for a light switch. Always turn off the power to the circuit before working on wiring.

To switch on the bulb, switch S 1 must be closed to complete the circuit and glow the light bulb. Use the suitable voltage and ampere rating of switch with appropriate wire size and proper size MCB according to the load rating. Four or more switches Both of the three way switching diagrams can be extended to four, five or even more switches. Electrical Technology 2 4 minutes read. Earth wires are not shown. Click image to enlarge. Also note that home wire colors may vary according to different areas. Fig given below shows the basic connection of light switch and their position i. Usually the third wire passes the middle intermediate switch but is joined in a separate terminal block. More common in domestic properties. Two wires between each switch. The middle switch is an intermediate type. Notify me of new posts by email. This is also known as the 'conversion' method, since it is the easiest way to add a second light switch to an existing circuit.

.

Contact the authorized and licensed electrician for switch installation if you are not sure about the wiring diagrams. Three wires between the two end switches, probably using 3 core and earth cable. Such an arrangement is not permitted, as isolating only one of the circuits leaves live wiring depending on the position of the light switches. Notify me of new posts by email. One way switching Single switch. Most likely to be found with wires in conduit. In addition, always use and connect the earth wire direct naked wire to switches, and electrical appliances from earth link in the distribution board to reduce the risk of electric shock and hazard which is not shown in the figures above. In short, the color for common terminal is different than other terminals. Unfortunately, this is usually encounted in stairwells, with the line from the downstairs lighting circuit and the neutral connected to the upstairs lighting circuit.
