Current switch is a straight-through structure design with isolation withstand voltages up to 2000V and hysteresis of less than 1%. It can be used under strong magnetic conditions.
The switch does not limit the number of opening and closing, the reaction speed reaches ms level, and the LED indicator can indicate the working state of the switch.
- High-power MOS tube non-contact electronic switch, the outer casing is made of self-extinguishing material ABS.

I use this to monitor when my septic pump runs, using a ZWave Zooz Zen17 relay on my UDI Polisy/ISY controller.The lift pump plugs into a standard float switch that is down in the tank.I had to modify an AC extension cord that plugs between the float switch to the lift pump,so the hot/line (black wire) runs through the hole in this unit. After calibration it is a dry closed contact on the outputs, which short the sensor inputs on the Zen17. Therefore, when the Pump is running, the Zen17 detects and I can use to keep track of how many times, duration etc.

I needed a current sense switch to open and close a make up air damper for a powerful kitchen range downdraft vent. Wired this on the hot leg of the downdraft motor and it switches 24VAC to the damper and works great.only detractor is the green LED never lites. Not sure why or even how it can. Maybe because I am only switching 24VAC. would be nice if they included a spec sheet or some instructions.

Hice pequeña instalación: cable de energía (un polo ) pasa por el Hyuduo; de ahí conecto : la SmartTV, un relay Estado sólido 40amps y de este un toma corriente múltiple. del tomacorriente se alimenta un amplificador claseD (80W), el eliminador de un GoogleChrome. Al prender la TV con UN solo Remote, Prende Todo ! El control de Volumen de TV maneja todo. El Timer de la TV la apaga ( yo ya dormido..) y TODO se Apaga ! y no gasté ni $50 usd...

Works well. Has been in use for a few months without issues, going off several times a day.

I've been trying to reliably detect a doorbell button push for a long time. I've tried 16v relays, magnetic read switches, hall effect sensors, bridge rectifiers you name it I tried it. They all worked to a degree, but none of them were very accurate at detecting quick doorbell rings (like when the delivery guy drops off your Amazon packages). Every solution I tried failed to detect doorbell presses that lasted under 1/2 second. This little guy is extremely accurate. I wish I had come across it sooner. Its also the easiest to implement of all the solutions. Just wrap the lead wire through the hole a few times and connect your switch to the terminals. No external power source is needed to actuate the relay. This thing is Magic!Project:I didn't want to replace my traditional doorbell with a digital bell (call me old school, but I think a doorbell should sound a certain way). My goal was to detect the doorbell button press and send a signal to my home automation system where I can snap a picture from my IP camera and send it in a text message to my phone. Ya, I know there are a bunch of doorbell cams out there that will do this but I already had 95% of the materials in place. One of the huge benefits of this current switch is that you aren't reliant on another device to pass the signal to the doorbell, its totally passive which means if the part fails, it doesn't break the doorbell.
