I assume this pull cord switch is Not used for two way switching. Make the connections as follows;
Com = live feed in (RED)
L1 = switched live out to bulb/light (RED)
L2 = Not used for one way switching
Earth terminal =earth cable (GREEN/YELLOW)
The two black cables (NEUTRALS) require connecting together. This is normally achieved by inserting them in a single section of 5 amp terminal strip inside the switch housing. If there isn't room for it in the switch, make the two black connections in a terminal box mounted in the ceiling space above the switch.
