    As I understand it a soft on/off switch ramps the voltage/current up slowly, so as to reduce shock on components or in the case of a hand held power tool, it keeps the motor's torque from jerking the tool out of your hands.
    If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

    Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves
    .

    Actually, it's typically used to debounce a switch so you get a smooth single on-off transition instead of multiple bounces from mechanical switches. However, in this case, it's being used to allow a push button contact such as those found on calculators and keypads to power on a PIC. The PIC then keeps itself on with software, until a software command is given to power off. The power off command could be given after detecting a second press of the power button.
    If you follow the link to the original thread, in the first post in this thread, all is explained.
