Hi,
As a complete electronics novice I am struggling to get a LM35 to work
properly. I know it should be simple but for some reason it is not
working and wondered if anyone has any suggestions. I have a string of
6 sensors with a live wire from a 9v battery connected to each via a
rotary switch. The ground goes back to the battery and I measure the
voltage between the middle pin and the ground.

Sounds like you've wired them up incorrectly, or possibly they're
oscillating because you've wired them to long leads without any bypass
circuitry. Check the full data *** below, paying paticular attention
to the "Typical Applications" section:
