Current Sensing Switch Normally Open Current Sensing Switch Adjustable AC 0.2-30A SZC23-NO-AL-CH, JSTXSZ
The high power MOS tube non- electronic switch ensures efficient non- switching operation. It can handle countless open and close cycles an unlimited number of times without performance degradation and has a time of milliseconds.
The AC current sensing switch easily and accurately monitors the action current of 0.2-30A AC. With the built-in potentiometer, the user can easily set the desired action current.
LED indicators provide a convenient visual indication of the switch's operating status, allowing users to easily monitor and troubleshoot any faults.

I bought 2 and a 115v relay to make wide current switch

This product works as advertised. I had 3 different switches for lights on 3 separate circuits. I wanted to turn on a remote light that would illuminate anytime any one of those switches were on so I would know if I had inadvertently left the lights on. Ran all 3 switch legs through this and it works perfectly to do what I needed.

It tells me my pump is running or not on my rain collection tank.

I used this to run an infinity DC 6” diameter air venting motor with silencers to circulate air to different rooms when my MrCool heat/ac pump turns on. To control a higher watts/amp, use a solid state relay in conjuction with this device. Still flawlessly working after 1 year.

working as expectedUpdate, the device i now failing. It just started t engage the associated relay at way lower current that i had previously set. to be honest the activation/engagement has become erratic. Probably got a bad one or the internal componnet are shoddy

This is super easy to wire and set up. Wired in our hvac air purifier so the fan starts the uv light powers up also. Saves the bulb lifespan.

I used to have a DLP projector, and had a current-loop sensor to bring the screen down via an X10 module when the lamp was on, and back up when the lamp was off (even though the cooldown fan was on). However, upgrading from XGA DLP to 4K LED means that there is no fan, and power consumption is a measly 0.4 amps max.This sensor replaced the old one, and I set the sensitivity so as soon as the LED fires up it closes the normally-open contacts which causes the X10 module to send the command to actuate the electric screen. When it's turned off, the screen comes back up.There were no instructions with it, so the only question I had was "do I turn the pot toward H or L to get the desired sensitivity." Fortunately it has a red LED (closed contacts) and a green LED (open contacts) so I just kept turning it clockwise (toward H) until it went green. Then turning on the projector made it go red, trigger the NO circuit, and voila, screen drops down.It took me longer to open the wrapping and unbox it than it did to set it up and use it. I also managed to drop it from about 4ft (1.2 meters) and it bounced off the tile floor undamaged.Definitely worth it if you have the application/need for it.Ehud GavronTucson, Arizona US

Used to sense power draw on load line of 110v attic fan and activates a zigbee contact sensor when closed allowing me to remotly monitor exhaust fan through Hubitat/Sharptools. So far has worked great, ordering a few more to add monitoring to other load line voltage on 2 Furnace Blowers, Electrica Wall Heter and what ever else I find I need to know if on or off. Wishing price point was a litle lower.
