To put it really simply you would not need a relay as you will be using
switches to drive the relay, you can do it with just 2 way switches wired in
parallel, (parrallel is OR, series is AND)



input 1 on first switch (2 way switch)

input 2 on second switch (2 way switch)



then for arguments sake wire both sides of the switch to a bulb, then earth
the bulb.



Either switches will turn on the bulb, or both together,

if both are off the bulb will be off



you could do it with a semiconductor logic gate, but 2 switches would do



hope that makes sense
