Computer Off Switch

-

How often does it happen that you close down Windows and then forget to turn off the computer? This circuit does that automatically. After Windows is shut down there is a ‘click’ a second later and the PC is disconnected from the mains. Up to now there were no mains switches available with a magnetic coil to turn off the power supply voltage, but now one is available from Conrad Electronics , with the article number 70061 for a price of 12.95 Euro (approx. £ 9.00). Surprisingly enough, this switch fits in some older computer cases.
