What are these called......?

and in the case of the first one, can you get one that has 2 on/off switches? Thanks.

I'd call the first one a surface mounted fused isolation switch, the lower one is a surface mounted junction box

The box and the front can be bought separately. 

Do you need it fused? haven't seen a twin switch with fuses but you can if its ok for them to be unfused

What is it powering?

Apologies - I'd wandered off there. The unit in question is in a garage. It has 2 motion sensored security lights plumbed into it - 1 external light and 1 internal. The outdoor light is playing up ie. not going off after it's been triggered into action. I'd ideally like it to be replaced but have it's own switch so that if it happens again, I can just switch it off without losing function from the internal light while I await a replacement. Thank you.

So the easiest thing is probably getting an electrician to put in a 2-gang light switch after the switched fused spur so the two lights can be switched independently of each other, but with both of them still having fuse protection.

Would that mean just plumbing in some wire (you'll be relieved to hear that I will not be touching any of this!) from the box I've got to a "normal" double light switch? I'm just trying to figure out if it's worth replacing the faulty light or just getting an electrician to disconnect it completely. What I decide depends on how much hassle is involved in what's suggested. Thank you.
