ALL European 2-pin 6 A plugs are reversible, and 3-contact plugs used on the Continent are reversible (there are two kinds, one with 2 power pins and side-contact for earth (called 'Schuko') and one with a third pin for earth). The standards you cite are written so that the product is safe, whichever way round the plug is inserted. You do not need a double-pole switch; in fact that can be a disadvantage, as it brings the two power conductors close together in an assembly with mechanical movement. A short-circuit at some stage in the life of the device is not improbable. Also, the insulation can fail, usually with smoke and small-scale flame, accompanied by a loud noise.

However, I am not finding support for this in standards such as 60335-1, 60601-1 or 62368-1. Your thoughts will be appreciated, oh experienced group, on: --safety issue involved --standards that do require double pole (sometimes referred to as "all-pole") mains switches.
