How to connect switch to electric box containing 3 grey (twin and earth) cables?

Question

The circuit breaker belonging to kitchen tripped today and I narrowed the problem down to faulty switch controlling my fridge.
I immediately removed the switch but I forgot to take picture of previous connection.
Please can someone help me with connecting new switch?

Greens go together. These are ground.
Blacks go together. These are neutral.
Reds go together, except one which is separated from the other reds by the switch.
Two of the reds will be live (or with the power off will measure as being already connected) these two are the ring main and they go together.
Judging by the layout in the box the two reds coming from the top are probably the ones that go together.

Looks like a standard UK ring circuit.  The chances are that the top two are two sides of the ring, and the bottom one is to the fridge.  It should be obvious if the fridge outlet is immediately below the switch.
So the two top reds go to the "in" L side of the switch.  The top two blacks go to the "in" N side of the switch.  The bottom red goes to the "out" L, the bottom black goes to the "out" N, and all the earths go to an earth terminal.
