Hi everyone,

Bit of background : I have put a double switchable outside socket which i spured off the outside power supply to the garage.
This socket provides power to my deck lights, which i have to switch on by going outside flicking the switch to 'on'.

I decided to try to make the deck lights switch on from the inside, so i thought i would link the power suplly to a switch inside the house.

A pic: wire from power supply to inside the house. and back into the double socket


Back of the switch



Now the problem starts:
I was going to fit a standard 1-way switch, but accidentally picked up a intermediate switch. Now the place i get these switches are a 80 mile round trip

Back of intermediate switch:


Here's the question how do i wire up the intermediate switch so that when i leave the double socket switched on, i can switch the lights on and off from the inside. I.e be able to provide and cut the power to the double socket.

Hope this makes sense!?
Diagramatic answers would be brilliant!

Cheers
Ben
