3 gang switch

[TerryD]

Hi, I am a DIY enthusiast and got water in an outside 3 gang, one way switch.
I took a photo of the wiring and will, of course switch off at the board when replacing the switch.
A new switch has arrived with 1,2,3 on it with no common.
I have attached the live wires to terminal1 and neutral to terminal 3 but no lights !!
What should I be doing?
