Bathroom pull switch replacement

[Calculus]

The cord switch in my bathroom is showing signs it is about to depart for Valhalla. I had a look on the B and Q website and it gives a choice between a 1-way and a 2-way switch. Can anyone tell me which of these I need? Here is a pic of the old one:

Thanks,

1 way.
The 2 way is used if you have a second light switch that controls that light, like a stairway/hall.

You only need a 1-way.

You can just as easily use a 2-way if you want.

The present switch looks like a two-way.

Incidentally, your lighting circuit has no earth. This is not dangerous as it is, but make sure you don't use any class I (ie metal) light fittings or switch plates. The back boxes of light switches should not be metal either.
Make sure anyone who works on your lighting circuit is also aware of this, just in case.

The earth may be tucked away behind the switch base.

There's definitely no earth; I fitted a new bathroom light last year and there were only live and neutral wires, including in the roof space above the bathroom.
