Kato 24-850 power isolation switches

[Markn]

I got some Kato 24-850 power isolation switches albeit second hand. However they didn't come with anybl instructions. 

Can anyone tell me how is wire them in. 

They've got the standard Kato plug and two connectors above. I am hoping to be able to use them to isolate a few sidings as my layout is fully live if that makes sense.

Many thanks.
