Product review (1 stars): Fire hazard. Don't buy it!
The contacts on this switch are faulty, When you are turning it on or off, it causes the connected power supply to arc. Everything is wired correctly. Using a power strip to turn things on and off, while routed through this switch, works just fine. The connections are correct. However, when you try to click the lighted switch on or off, the sparks in the power supply start flying. Very dangerous and cheaply made. Don't buy it!
