Exchange
switch or commonly known as the hotel switch, switch hallway, staircase
switch, is a series of electrical installations with the principle of
controlling one or several light by two switches, point is that we can
turn on and turn off the lights with two switches independently, for
example, we put a lights
in an area of the stairs, then we put the two switches for the lights
with the position of the switch is placed in the bottom of the stairs
while the switch is again placed in the top of the stairs, when we're
down and turn on the lights with a switch under then we walk climbed to the top of the stairs then to turn it off do not need to go
down the stairs again, but just turn it off using the switch located on
the top of the stairs.

For more details, please refer to the installation of network development below:

| CIRCUIT OF EXCHANGE SWITCH |
In
the development scheme, you can see there are additional cable
connection and are connected to a single switch to the right of the
picture. The
concept of an additional switch is quite simple, the lights will turn
on the switch condition of the switch in position "ON". If you switch from one switch is positioned to "OFF", then the light will die.
Initial installation (left scheme) can be done by placing a light switch (main switch) on the first floor area. After the home position lights installed, add additional wires to the switch on the second floor (right scheme).
Difficulty using this method is currently workmanship cable connecting to the additional switches on the second floor. If the position of installation of the lamp housing is high enough, the process Becomes quite cumbersome. You can do the wiring connection before the house lights installed, but it will be even more upsetting when the house lights about to be paired.
