The time between changing the state of the switch and the affect it has on the bulb can not be any faster than the speed of light.
In Derek's example the switch and the bulb are 1 meter away from each other and therefore the time is 1/c seconds, i.e the time light takes to travel 1 meter.
The topic is definitely a little confusion, but there are no GR violations.
