Switching switches

[rizsher]

All the bathroom switches in the house have 2 switches, one for the light, 2nd for timed extractor fan.

All of them, save 1 the first button is for light, 2nd for fan except the master bathroom.

I opened up the box and saw too many wires for my comprehension. The grey wire goes to the 1 way terminal on the first switch (for the fan), and brown to the 1way terminal on the second switch (which controls the bath light) - see attached

If i want to change so 1st switch turns on light, and 2nd switch controls fan, can I just switch the grey and brown cables?
