Having taken a look, the switch in the cooker hood is a radio-style
switch with one button for the lights and three interlocked adjacent
buttons for the fan speed. All the switches are mounted on one frame.

It certainly doesn't use a standard microswitch and I can't see any
rating printed on it.

Would an electronic transformer be a safe additional load then ?

I wouldn't risk it. Fit a relay. Cheaper than having to replace the switch
bank - even if you can get the spares.
