Who knows? Maybe the Zigbee has moderna 800 style "integral switch action".

I'd be interested in the reasoning for integral switching and what it adds over shuttering. When I'm at the end of a 30m extension cord with a power saw I unplug it before adjusting the saw, I certainly don't walk back to the switch.

Especially now that insulated phase and neutral pins have been standard for a decade or two

I would hope that the amazon one doesnt really comply, since its basically an open face of live contacts once the faceplate is removed to access the reset button. The faceplates come off with no tools and in the one glass plated outlet I imported to have a look at would come off if you yanked on the cable in the plug at an angle.

Yanking on any plug is liable to lead to a number of bad outcomes...

 

Bare wires and smoke come to mind.

 

NZ compliance seems impossible for automated outlets.
Although I guess the new PDL one (mentioned above in this thread) could be automated.
It'll be an expensive solution, as no-one else in the world needs to use that loophole.

Switched sockets appear to be a silly legacy from the UK.

 

Early DC sockets could arc badly when plugs were removed - and were fitted with shields (for your hand).
Switches were more elegant - and replaced shields.
That type of arcing doesn't happen with AC.
When AC came along, new British standards were written as un-switched.
And Britain has careful electrical codes.
But British customers wanted switches - they had grown accustomed to them.
So, although not required by code, British sockets often still have them.

 

So, neither the UK standards, nor anyone else in the world, appear to think they add to safety.
NZ is unique in requiring them.

 

A bit like our left-hand rule in traffic, it may be a bad idea whose time is up.

I honesty don’t see the issue. There have been un-switched outlets available since forever and you can still buy them. There is nothing stopping you from installing certified control gear on outlets and there are plenty of products available for this.

AS/NZS 3000 is a joint Australian & New Zealand Standard. Some clauses have regional differences but there doesn't appear to be any in 4.4 Socket Outlets.
