Q:
You have 2 switches to control the light in the long corridor.
You want to be able to turn the light on entering the corridor and turn it off at the other end.
Do the wiring circuit.
 
 
 
 

A: this is how I would connect the switches

 
 
 

A2:
let's put switch "A" at one end of the corridor and the switch "B" at the other end. Then, lamp = A XOR B.
 
 
 

R.K:
XOR is correct for your diagram. However, if you connect switches A and B differently, then XOR is inverted. That means when both switches are up (1) OR both are down (0)
