The current they use is very small and harmless. How harmless you ask? Remember the voltage tester you father had, the one you touch to a wire and put your thumb on big metal plaque? That's the same kind of halogen bulb in there, yet you don't get shocked or anything. The light in the switch depends on the circuit being complete, it wont light otherwise. | |
