Anti-Standby Switch
Also works with a remote control!
Energy Saving may well be a must-have feature for home entertainment products sold today but there are still millions of older and even not-so-old appliances that are guzzling far too much juice in the all too convenient standby mode. The anti-standby switch described here saves the planet’s energy—and yours too!
