GEWiSS IP55 On/Off Outdoor Switch

[Taylorsquad]

I bought a GEWiSS IP55 a long time ago and have only just got round to using it. Along the way I have lost the wiring diagram. As it's an older unit the back of the switch block has three connectors numbered 1,2 and 3. Can anyone tell me how to wire it correctly please?

It's a two-way switch, is it?

Are the terminals in a triangle?
If so, one conductor to the single end (1 ?)
the other conductor to one at the other end (2 probably, if it works 'upside down' then 3)

That's 5 seconds work with a multimeter to test it out.
