hi. I went to put a new light switch in my porch that controls the light in there and the front door security light and when I took the old switch off the wall I found what you can see on the picture attached. Can someone explain why it is wired up like this?

To utilise the same supply for both switches.
the black in with the red appears to be the L feed. this is linked to the other switch, so tat both have a L. the blacks in the L1 terminals should then be the L's to each light.
First light switch I have seen on here without a load of copper conductor exposed.
But its let down by a lack of identification on the conductors.
And the rarest of things in a DIY lighting query - a picture before it is taken apart
Top spot.
It is a good spot because it appears the lines are looped at a block connector with the neutrals to the switch, possibly. Needs addressing.
Definitely as there could be incorrect polarity.
