Switch for Switch-Free Power Supplies
Portable radios, CD-players and cassette recorders that can also be operated from mains power often do not have a mains power switch, but instead are switched off on the ‘DC side’. This means that the power supply is permanently connected to the mains network if the mains cable is not unplugged. The situation with equipment requiring a mains adapter is similar. This is not ideal for the environment or for your pocketbook.
