Hi, thank you for your product enquiry.
The decision between Single Pole or Double Pole switching is often a personal one, as both are considered safe.
The difference is that SP only disconnects the Live carrier (leaving the Neutral carrier connected, which will allow dissipation of any stored energy if the device has done this) where DP disconnects both.
In both cases Earth remains connected whilst the plug is in the socket for safety reasons.
