Basically, this circuit is same like staircase wiring circuit using three-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 three-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 3-way switch while entering the corridor and turn OFF when leaving the corridor or reach to the room door by switching OFF the second 3-way switch. In short, it is a three way switching circuit to control the lighting from two different locations.
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.
