Wiring help - replacing lighting switches

[Rbods]

Advice please. Changing old switches. I thought the old switch was 1 way but has 3 wires - yellow to com, red to L2 and blue with red sleeve to L1(switch live?) see photo. Is the new switch I’ve bought suitable? If so, which wire would go in the N/loop terminal?? Thanks

Your new switch is one way. You need a two way switch.

Many thanks. Thought as much. Have just found the other switch connected to the same light! Never knew it was there.
