PWR-SWITCH is optically isolated EU style power load switch for up to 3500W, 230VAC/16A and can be driven with any microcontroller, Arduino, EPS32, or Linux computers directly with 3-24V

PWR-SWITCH hides the high voltage problems from the Arduino, ESP32, Raspberry Pi, Beaglebone, OLinuXino developers. It has 1500VAC optically isolation and can drive high voltage up to 230VAC / 16A loads safely.

To switch On or Off the loads from 3 to 24VDC can be used, so you can drive the loads with any microcontroller only 1mA is necessary to trigger the switch.

PWR-SWITCH is with EU stype plug and receptacle, so to use it in US or in UK you will need some of these:US to EU adapter, EU to US adapter or UK to EU adapter.

 PWR-SWITCH has CE-EMC and LVD certification.

Green LED show the switch status.

    I guess this is built around a mechanical (relay) switch, what is the lifetime of the contacts?

    Interresting, however this would have been so much interresting if the PWR_SWITCH would have been able to provide the power to the extrnal card that drives the relay! If my understanding is correct you would need an external power supply, most likely connected to… another 230 plug!!!!!
    If i may, i would suggest to have ‘internally’ some space for a dedicated board, which could be choosen to be able to supply the Arduino/RaspBerry/ any other…
    There i would seen a great interresting ‘all in on’ plug that would settle the problem of 230v isolation vs low current boards…

    Looks interesting. Wonder what is inside beside a relay. I guess it is a 230V coiled relay that is switched by an optocoupler with triacs inside.

    I guess if there is enough space, it would be possible to design an own PCB inside of the plastics. Current feedback would be surely interesting or a power supply.

    Definitely I have added this item to my ToBuy list 🙂

      There is high voltage inside, if you want to open and add PCB be careful as high voltage is dangerous. We intentionally didn’t open source this product, to not encourage people, who have not worked with high voltage before to experiment.

        Exactly!!! high voltage should (IMHO) be out of hands of non professional. Therefore, if this would be able to provide power to the controlling board it would have been a very easy to use conveniant product. (we could even imagine a hall sensor to measure consumtion)
        Thanks anyway for the clarification! And thanks for all your open hardware products !

    Thanks for this product. It looks interesting.
    At least in France, common 3 poles power plugs are not compatible with it due to the ground pole being different.
    Do you believe that you could find a solution to produce another version that would be also usable in France ?
