Corridor Wiring Circuit Diagram – Hallway Wiring using 2-Way Switches

Hallway and Corridor Wiring Circuit Diagram using Two Way Switches

Basically, this circuit is same like staircase wiring circuit using two-way (SPDT) switches used to control the lighting circuit in a hallway and corridors. In corridor wiring circuit, a lighting point is controlled from two different locations using 2-way switches.

In corridor wiring circuit, a person can turn ON / OFF a lamp by entering or leaving the corridor. For instance, a person can turn ON the bulb by switching ON the 2 way switch while entering the corridor and turn OFF when leaving the corridor or reach to the room door by switching OFF the second 2 way switch. In short, it is a two way switching circuit to control the lighting from two different locations.

Hallway - Corridor Wiring Circuit Diagram

Requirements:

ComponentRatingQuantity
MCB120V or 230V, 5A1
Two – Way SwitchSPDT,  5A6
Light Bulb40W3
Wire Size1.2mm PVC2 – according to the length

Procedure:

  • First of all, turn off the main breaker to make sure the main supply is switched OFF.
  • Connect all the switches to the earthing / grounding terminals (not shown in the fig)
  • Connect the neutral wire from MCB to the second terminals of all light bulbs.
  • Connect the common terminals of Sw #1, Sw# 3 and Sw #5 to the live (line or hot) wire from main breaker.
  • Connect the common terminals of Sw #2, Sw# 4 and Sw #6 to the first terminals of each lamp.
  • Connect the upper and lower terminals of all switches with two auxiliary wires following the sequence as Sw1 – Sw2, Sw3 – Sw4 and Sw5 – Sw6.
  • Do the proper earthing and grounding according to your local area codes.
  • Now turn on the main breaker to make sure the circuit is working properly as planned.

In case of single corridor or single lamp to control from two separate locations, you can connect the neutral to the lamp first terminal and phase (hot or live or line) to common terminal of first switch. Connect the common terminal of second switch to the second terminal of lamp. Finally, connect the upper and lower terminals of both switches with two auxiliary wires. This way, you will be able to control a single light bulb from two different locations using two SPDT switches.

Additionally, If you want to control the light bulb in a corridor from three different locations, you can use an intermediate switch in the middle of two switches.

Working:

As mentioned above, we can control a single light bulb from two different places using 2-way switches. In corridor wiring circuit, suppose a person entering the corridor and want to turn ON the light, he can simply switch ON the 2 way switch to do so. When he reach to the room or leaving the corridor, he can again turn OFF the light bulb by switching OFF the SPDT switch. No matter what is the switches positions i.e. upper or lower, the circuit will work the same way as mentioned above.

The following fig shows the working of the corridor wiring circuit.

If you still unable to get the working of the hallway circuit wiring, the following animation gif and video shows it how actually it works.

Note: Use the suitable voltage and ampere rating of switch with appropriate wire size and proper size MCB according to the load rating.

    That’s not right at all. A “2 way” switch controls a circuit in one direction. A “3 way” switch controls from two directions.

    1. Two Way or Three Way Switch?

      “Three-way” is the North American (USA) term for this type of switch used in the following tutorial. Most English-speaking countries (UK/EU) call them “two-way”. The term for the pair of wires connecting the two switches also varies: “strappers” to the British and “travelers” to the US.

      Please don’t kill me to mention it 2-Way switch instead of 3-Way switch as whatever we have used is the same thing for specific purpose.

      1. Agree 100% licensed in NJ since 1984.

  2. I think this is great for refreshers.
