Old versus new - 9th Sep 2014

What is the difference between an old powerpoint (pre 1970) and a new one? They do the same job, the new one looks more modern but is it any better?
The short answer is YES.  
The majority of modern powerpoints have "safety shutters" which isolate live terminals from the user when not in use. Much like a sliding door, the shutters slide across when an appliance is unplugged, making the powerpoint 100% safe for toddlers and children.
Light switches from the same era have exposed contacts on the inside of the wall cavity, allowing dust to build up. The combination of dry dust and the spark created by switching off a circuit can create a fire hazard inside your wall.
The live contacts of modern switches are fully enclosed and protected from dust.
