We have an outside passage light which is controlled by an outside
switch and an indoor switch - it can be switched on or off by either
switch - I think this is called a 2-way switch?

I'm fed up with the number of times the outside light is left on all
night.

Is it possible to get a switch which you can push to switch the light
on, and which will automatically switch off say 5 minutes later. I'm
sure I saw something like this many years ago - it was a circular
button which you pushed in and it slowly moved outwards and switched
the light off again after a couple of minutes.

You can still get these; they're pneumatic. There are also electronic
versions.

Two way is tricky, but if they're going to go off in 5 minutes, just
wire them in parallel. The existing cabling will be able to handle that,
with a wire to spare.

The other issue is weatherproofing. I haven't seen one suitable for real
'outside'.
