Crabtree 4013/3 Double Pole Switch with Neon 1 Gang 32 Amp

I retrofitted this in an awkward location where I could not see the screws, i.e. I was wiring it up blind. This revealed several weaknesses in the design: the (grub) screws weren't captive and fell out a couple of times. They are not at the bottom of suitable wells so your screwdriver is not guided to them, it can go into blind holes instead and it is almost impossible to tell this by feel. Their heads are not large, making it extra difficult to fit the screwdriver blade into them blind. The moulding which holds the screws appears to be two relatively flimsy mouldings snapped together.Overall, it works, and fitted a standard junction box, but I feel it is not the best designed one of these I've used.Update: a couple of months after fitting, the switch stuck in the "on" position. That's very worrying - perhaps something has melted in it. It is feeding power to a shower pump. So I have downgraded this review from 3 to 2 stars.
