Seriously, speaking as an qualified electrical engineer, you shoudn't get shocks off lightswitches. If you get a blue spark jumping across to your finger that really hurts there's a probably a wiring fault, and if at work you should report it.
Static electricity shocks such as you get from car doors are completely different. You should be able to tell the difference.
