wonderiing if anyone could clarify whether this is best practice


basically i'm in process of swapping all my light switches in my house for a certain type, they're remote controllable and can do all sorts like dusk to dawn features blah blah blah!... i've come to do the switch that controls the porch light/security light which is located in the front bedroom (directly above the porch & security light) and noticed the switch plate had got a fuse, so i turned off the lights mains circuit to take a look at wiring out of curiosity etc and upon testing the switch to make sure it was off it was actually still working!!! (good job i'm always cautious and check!! as they say curiosity kilsl the cat!! lol)

realised it's actually on the sockets circuit! is this normal? any reason it's on the sockets circuit? and assume the fuse is so if the lights blow for whatever reason it doesn't trip the CU and so that the lights work on 13A?

haven't checked the wiring but i'm assuming it's not going to be possible to swap with the light switch because it's a different current? 13A?

This is the switch spec i'm using to replace existing
Voltage: 110~250V/50~60Hz (Max.)
Current: 5A (Max.)
Function: Home Light Remote Touch Control /dusk til dawn features
Total Rated Load: 2000W
Operating Environment: -30~70 centigrade; less than 95% RH

Any advice, explanation/an education as to why it's on the sockets circuit.

Thanks in advance!

Well done. :)

Current(A) is drawn by the loads(lights), not supplied to them so it makes no difference.
It would normally have a 3A or 5A fuse.

As above.

Easier to access ? Makes no difference to the switch.

wow! thanks for the quick responses that's ace!!

So does that mean it doesn't need the fuse unit still in place? and i can do straight swap for new switch?

If you want to fit your new switch you need to retain the fuse unit to protect it

if i do, do they do a seperate fuse unit, assume it'd need to be fitted between the light and the swich?

im probably confusing / overthinking it... i kind of understand idea of fuse and it's purpose just don't know when you should or don't need to use one. :)

haven't got space for double patress box as directly next to the switch (mm's apart) theirs a double socket and the other side is the brick wall (it's in the corner of the room

You should retain the fuse and you will be able to find a matching unit.

Between the supply (socket) and switch so if you find from which socket it is wired you could place just a fused unit (no switch) next to it, then just have a normal switch.

You could re-use what you have, but other people may turn the switch off? and annoy you and the fancy new switch.

Therefore you may want to buy just a fuse unit.

i've decided not to use my fancy switch instead i've found something else which might be suited for what we want but just wanted to query this with you guys... i know i'm probably asking some really rookie questions but want to make sure i do it right

i've got one of these:
http://www.maplin.co.uk/p/lightwaverf-in-line-relay-n64ll

however the fuse in this is 13A and the fuse in the current switch is only 3A... i assume i should replace the 13A with the 3A one BUT they are different sizes!?!

any advice, also as this device is fused - is this doing the same job?

if this works i will put the inline relay in the back box and put on a blank plate (and put label on blank plate)
