A power cord that switches 120VAC (up to 15 amps) with a DC control voltage of 3VDC @ 3ma to 12VDC @ 30ma

"The easiest way to control an AC device with an Arduino, Raspberry Pi, Beaglebone or any other DIY controller."


  • No exposed 120VAC voltages and no dangerous 120VAC wiring required.
  • Plugs into standard 120VAC 3-prong household outlets, power strips, and extension cords.
  • Eliminates the exposure of hazardous voltages in DIY projects, classrooms, and on development workbenches.
  • No special 120VAC wiring when deploying new products and custom solutions.
  • Can be installed by non-technical users: Instruction sheet for PN 80135 or PN 80135-NC
  • 5300vrms isolation from the 120VAC circuit. Indoor use only.


  • Easily inserts between power source and corded electrical devices.
  • Switches up to 15 amps with a control signal as low as 3VDC at 3ma. Ideal for use with battery operated controllers.
  • Connects directly to Arduino, Raspberry Pi, Beaglebone or other 3.3 or 5 volt MCU without the need for driver transistor or buffer circuit.
  • Two-wire control signal connects to terminal block (30-14 AWG) and a separate power supply is not required.
  • LED indicator shows status of control signal.
  • Connect input plug to wall outlet or when using multiple units, to a power strip.
  • Connect output receptacle to a single powered device or to a power strip to control multiple loads.
  • Output devices may be 3-prong or 2-prong appliances or lights.
  • Convenient safety ground connection available for grounding external control circuit.
  • PN 80135-NC shipped normally closed but can be rewired for either NO or NC.


  • Purchase only what you need. Use one unit for each controlled circuit and add units as required.
  • Each unit comes complete and connects to all standard 120VAC 3-prong wiring devices.
  • Eliminate the need for electrician fees or electrical wiring permits.
