Some national plugs may not be reversible but those countries also widely acceptable to 2-pin Europe plugs or 3-pin Schuko plugs that are reversible.
The safety standards do not need DPDT switch in compliance. Even though the single pole is not restricted to be on the live wire. Thus the switch on neutral wire is still considered acceptance. Needless to say, single pole switch on live wire and DPDT switch are considered the best practice in safety perspective. As I see less and less this practice is implemented in the latest products due to no support from harmonised safety standards.

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.
