I think you really misunderstand the question or I have not stated it well
for you. Let's take a power strip instead. I'm looking at one right now. It
has 6 3-prong sockets for a a 3-prong plug. If I stick a plug into it, it's
very difficult to get it out. This particular model is pretty decent about
it. A solid pull will free the plug. On another such device, I just about
have to take a plier and screw driver to a plug to get it out of the
socket.
I hope I don't sound too holier-than-thou, but I think this is just down to
quality of springs.
Over here in UK, the power strips are bigger and chunkier, so there is more
area to grip, hence more gentle springs.
The current is lower - anything over 13 amps is considered special - so the
demand on the contact is probably less.
Plus the general build quality is better than the stuff I saw in Walmart and
Home Depot, and hardware stores.
Talking to colleagues in USA, the concensus seemed to be that you can get
really cheap stuff, but it is not good quality.
For instance, in Walmart I bought a double wall outlet socket for 45c (plus
a few c tax).
The equivalent over here would be more like $5, and twice as large.
One USA colleague said he'd heard from a Fire Protection guy, giving a
safety lecture, that to reduce risk of fire,
a) don't take plugs in/out unless necessary - to reduce usage
b) replace the fitted, usually cheap, sockets in the kitchen with ones
costing at least $3 each - to increase quality.
