Auto-Off Timed Outlets


  1. Press “TIME COOK” then enter the time in minutes and seconds, then start.
  2. The relay closes the circuit and the outlets are energized.
  3. When the timer runs out, a piezo buzzes and the outlets shut off.
  4. The relay on the microwave’s circuit board is 120-250 volt at 16 amps, so I’m fairly comfortable it will handle one or two 40-watt soldering irons.
