*Probably*

Red (live) from fuse to COM---COM---COM
Red (live) to light 1 to L1 on switch 1
Red to light 2 to L1 on switch 2
Red to light 3 to L1 on switch 3.

Black (neutral) from fuse and blacks to lights commoned together in a piece
of terminal strip.

All earths sleeved green/yellow, commoned in terminal strip and linked to
back box if metal.

Identify the terminals carefully - you may find the middle switch terminals
are 'upside down'
