Thats right DJK, the flush floor mount socket outlets in NZ are made of die-cast metal.
The question here is : Can our plastic wall mount socket outlets withstand the impacts experienced by the floor mount sockets ? ?
I think not. The plastic wall mount sockets incorporate a switch which would easily be dislodged by a high-heel ( good scenario DJK ! ) or even worse, a couch leg with 3 people on it.
I agree with Trumpy that the plastic face of the socket is up to the task, but I think the switches are the achilles heel.
Floor mount sockets don't have switches.
As for the lid, DJK suggested that they keep dust off the contacts. It would make sense that clean socket outlet contacts function better than dust-covered contacts.
