New 1 Way Bathroom Light Switch

[glass back]

Hi
I have removed the old pull cord switch, and noted where the old cables went;
The red into COM
Black into one marked 1 way
Neutral into the one marked earth
The new switch has the following;
COM, L1 and L2
Where does each wire go please??
I am sure it is simple but with the switches being different I am confused.
Do I have the wrong unit?
Many many thanks
