One LED and 3 switches

Turn on/off a light bulb in a room from 3 different switches.
The central switch behave like an inverter. This switch need to be a DPDT switch, but there isn't one in the EveryCircuit library, so I have used two SPDT. During the simulation, if you want to switch the central switch you need to switch both the central SPDT switches.

there is another switch which is called a changeover switch that connects four poles either in parallel or across, this is used in household lighting circuits.

Its called a four way switch, it goes in between the 3 way switches. A Dpdt will allow you to improperly wire it and burn your house down, while a 4 way only operates when properly wired.

Hi nammachdien, what's wrong? I checked every state and it's ok. But, also, I'm not an expert :) So your comments are welcome.
