  • Well there’s cost. Think about how many outlets in an office or home.

    You may not understand the engineering of “UL” or safe switches because they would have to have full current of a short going through them, you have arcing, lifetime toggles, the ozone weakening the molded plastic, etc.

    With most outlets (receptacles) there is a solid copper bar that goes from the wall wires to the part that pushes against the prongs of the plug. With a switch it’s slightly more complicated and would you only break the hot? What if someone wired outlet backwards?

    Sure you could make every plug involve a fuse, circuit breaker, arc fault, GFCI, and a switch. And a USB transformer and nightlight.

    It could help though in many homes if you had only one outlet wired to a switch, and could help with parasitic current draws of almost everything modern.



  • No. It’s ambiguous. In a math book or written by anyone that actually uses math, you don’t have a “%”

    You group stuff below the line, and you use parens and brackets to group things like (a + b) and (x)(y) so that it is not ambiguous.

    2/xy would be almost always interpreted differently than 2/x(x+y) which is ambiguous and could mean (2/x)(x+y) or 2/[(x)(x+y)]
