They're usually a triple light switch, but with a large rocker
jammed onto all the actuators.

And normally mounted at high level so an exact match with a light switch
will not become an issue.

I been on few new housing estates round my area and noticed how these
installations had been done on new builds.

The light switch and TP fan isolator were mounted adjacent to each other
outside the bathroom/ensuite. Some estates also included a 3 amp FCU
adjacent to these. If the FCU was fitted, the bathroom light and fan were
all wired behind the 3 amp fuse. (The FCU should be fitted if the fan
manufactuter's instructions call for it).

Disadvantages of wiring the fan to the light are...
You always have to operate the light to get the fan to run, even during the
day.
At night you always put the light on, so the fan runs, whether you need it
to or not.

Mounting the TP isolator in a convenient position gives the option of
silencing the fan if it is not required.
