Finished a job where I had to use Volex flat plate outlets. Apart from the quality being **** poor, the switch mechanisms feel like they will fail any second, the holes for the cable termination being small - it felt like you could only get 1mm into the sockets! Don't ask me how I managed to get the 2.5mm in! Did the IR tests, got 80 - 100 MOhms - Completely acceptable - but pants! Stay away from these outlets in future! J.
