Connection of a two way (double) lighting system
A two way lighting system is a system which can
control a lighting point from two positions. In the connection of this system,
two 2-way switches are required to control the lighting point from the two
positions.
Let’s now look at how the terminals of the 2 way
switch looks like and how it is used.
It has 3 terminals (COM, L1, L2) see the figure below. One switch at position 1 and the other at position 2.

Now let’s look at the connection.
From the above diagram, connect the COM of Switch 1
to the live, then L1 and L2 of Switch 1 connected to L1 and L2 of Switch 2. Then
connect the COM of switch 2 to one terminal of the lamp and the other terminal
of the lamp to the neutral and you are done with the connection.

Now let’s see how it operates to put on the lamp.
- Pressing any of
the switch puts ON the lamp. In our case we press S1

Pressing the
other switch puts it ON.
Pressing any
again puts it OFF.
So we see that we can put ON and OFF the lamp at any
of the two positions.
A two way switch can also be of double gang (two 2 way switches in a single structure). See the figure below

Boom, you can now connect a two way lighting system.
