[quote author=trowelhead  link=1099690406/0#0 date=1099690406]I am currently in the thought ( ???) process of fitting an external light and switch to the shed at the rear of my garden.
The shed is seperated from the 'garden' by trellis and i was thinking of putting a light on the shed and the switch on the house side of the trellis so i can turn on the light before i get to the shed.
Question:What make would you pros recomend for the switch?I was thinking of the MK (bluey/grey colour) as it seems to be the preference.
I have some swa (3 core 1.5mm) to dig in (approx 2m) from the shed internal electrics to the switch,does the swa terminate directly into the mk(or other make) switch or do  you terminate into an ip metal box and then run cable(if so what type) into the switch?

Thanks in advance lads. [/quote]

The bluy grey colour is MK 'masterseal' it's the most expensive, and to be honest id go with one cheaper thats just as good for your purposes.

You could gland into the PVC switch box with the correct gland and seal's etc, however I personaly don't like glanding to anything other that metal boxes, however I would in your circumstances if you use 1 core for the earth, and the other 2 cores as in and out to the switch.

If your planning to do this by yourself then theres a few things you will need to know, for starters there are BW and CW type SWA glands, you would need a CW for your switch if it's exposed to the weather.

CW glands have an extra internal seal to stop the water getting in to the connections.

Hope this helps

MK Masterseal are the boys, available in white now aswell, and other colours to-order for large quantities.

They are the Rolce Royce, and will last...

NO! you MUST gland the SWA
you cant not attach the armour to earth anyway...
you have to gland it so the gland does it automaticly

Yea, I regularly gland directly into a Masterseal socket or switch.

You must earth the armour at atleast the supply end, and preferably both.  As you are using plastic enclosures, the banjo that comes with the gland is used to achieve the connection.
