2 gang 2way switch helpline

[Alkaline_Steely]

Hello all
Replacing a switch at the top of the stairs. Switch does the bathroom light as shown in the picture. And also top of the stairs but has a switch at the bottom of the stairs too.
The old switch has com l1/l2 and com l1/l2 first part is com+l2 for the bathroom and com l1/l2 for the stairs light.
The new switch has
L1 and L1-1
L2 and L2/1
Any ideas where I start

Assuming with the lack of the l2 the downstairs link has nowhere to go so the switch is redundant in that respect

Agree. Looks like a 2 gang 1 way switch, which is quite rare from experience.

Yes
Was not attached to the switch but it was there. Now attached whilst I nip to Screwfix for another switch
