Description

A smart power saving in line power switch designed to remove mains power from a TV or other device in standby to reduce electric cost.

This design uses any infra-red controller with a 36 - 38kHz carrier. A long press of any IR button on the users remote controll will cut the mains power, a short press on any button will restore the mains power.

An override button is also on the power switch to switch on or off manually.

CAUTION: Ensure the load is suitable for the TRIAC selected, the TRIAC may require up rating and heatsink for bigger loads. This design will switch loads of about 600W without a heatsink.
