DON'T connect any of the pins to ground - ground (earth) is for safety and sheilding, NOT return current.
First you will have to identify the terminals - numbering is at the discretion of the manufacturer. With a multimeter measuring ohms, take readings between each of the switch pins with the switch in both on and off positions. You will find that there is an effective open circuit (no reading) on one pin - this is the internal neon connection. Connect this to mains NEUTRAL.
Connect mains ACTIVE to one of the other pins - if the light goes on and off when you activate the switch, it is the correct pin. If the light stays on all the time, change active to the other pin.
The remaining pin is now your mains out. Switches should always be connected in line with mains ACTIVE.
When doing anything with mains voltages, BE CAREFUL - 240V isn't very forgiving....
