Unknown Switch

I have recently bought a Swift Corniche caravan and have a fused rocker switch under the sofa on the offside. It lights up when operated but I don't know what it does. Does anyone have any ideas?


I would imagine from its position, it is most likely to be the isolation switch for your water heater. To test this out, make sure that the water heater is full and then switch it on and wait for the water to heat up.
