Controlling a Lamp by Six Places by using Two, 2-Way Switches & Four Intermediate Switches
In today basic home electrical wiring installation tutorial, we will show how to wire and control a light point from six different places by using two, 2-way switches and four intermediate switches.
We will use 2, two-way SPDT (Single Pole Double Through) switches and four intermediate switches to control the lamp from six different places.
Before go in details, we have to show the basic construction and operating mechanism of single way switch and intermediate switch.

We have posted a detailed post about What is Intermediate Switch & Its Construction, Working & Uses in Electrical Wiring
like using intermediate switch in basic home electrical wiring installations i.e. staircase wiring, two-way switching, three way switching as well as controlling a light point from different places by using intermediate switch.
Good to know: You can control a light point from many different places as you want by using two, 2-way switches and the required number of intermediate switches needed to control the light bulb (or any other electrical appliances) from different locations and places.
Requirements:
- Two Way Switches (SPDT = Single Pole Double Through) x 2 No
- Lamp (Light Bulb) x 1 No
- Short pieces of cables x 12 No
Procedure:
Just connect four intermediate switches in the middle of the two, 2-way switches as shown in fig below. The circuit will capable to control the light bulb from six different places. You may control the bulb from more than six places by adding additional intermediate switches in the middle of the circuit i.e. in between two, 2-way switches.
Working of the Circuit:
If both two-way switches are at OFF or ON position, The light bulb will switch ON and glow and the bulb may be controlled (To Switch ON or OFF) by pressing any intermediate switch. In other words, you may switch ON or OFF the light point by just pressing any switch no matter it is the two switch or intermediate switch.
Good to know:
- Switches and fuses must be connected through line (Live) wire.
- More wires and cables are required in this kind of wiring connection.

this is fantatic
Thanks
Purchasing the proper magnifying light could be a struggle. It will take understanding of these special units and perhaps, individuals include not dealt with these individuals plenty of to recognise precisely what to look for a single. They are typically utilised if you have to consistently look at physical objects at length or even if you have to complete any fine job that needs people undertake
This circuit diagram is very nice . Thanks…
Completely useless. Put an X on the first 4 way switch and you will see your circuit not working.
