Wireless Remote Switch,with 984FT Long Range,DC12V/24V/48V/72V RF Remote Switch for Anti-theft Alarms, Roller Lind Door,Gate Barriers Motor cycles (Two Remote Controls 12V)

Made a softwash system, works perfectly. Can switch from chemical to water in the click of a button from 50ft away with ease. Saved me tons of $.

I was pessimistic about the range for remote control. However, my usage was to operate a 12V apparatus in a garage remotely from another property about 500' away. There are three outside 8' high block wall in between plus the apparatus was behind a steel garage door. It never missed a beat. Faithfully "on" or "off". Both remotes that came with the unit work identical. One thing to note is that the relay is small in size. The polarity of the input and output is noted on the relay, but the markings are very small and hard to see plus right above them every terminal location has a little phillips screw design imprinted that is easily mistaken for a "+" indicator. Double check your hookup before energizing if polarity is important. As a note, I checked it using 24volts also and it worked well, but it was a test at short range...just wanted to see if it would work on 24 volts and it did. Voltage source was two small 12V lead acid batteries, either in series (24V) or parallel (12V).

Worked for one day then broke and they won’t refund me

I installed this relay switch inline on the power wires for my son’s 24V electric power wheels. It could not have been more simple! The power wheels model already had a manual disable switch to prevent battery drain when parked, so I just installed this relay after that manual off switch. Installing it like this prevents the relay from draining the battery when not in use. I like that the relay is a latching style, meaning it stays in the last state when it loses and regains power. This means it will stay off if you use it to disable the car, even if your kiddo tries to toggle it by power cycling. Performance has been excellent. Relay is nearly instantaneous, which makes it perfect for a parental safety override to prevent your little one from driving into a dangerous situation. Just press the off button and the car loses power and stops immediately.

They are not specific to one unit. In other words, when I turn on or off one of my pumps all of my pumps are equally affected. So, what they tout as an advantage of 984' range or whatever becomes a burden when you only want to control one unit remotely. It would be so easy to build these so they must be paired with a specific switch instead generically and indiscriminately shutting down an entire operation when all you want is to shut down or start an individual unit. A disgruntled employee or business competitor could reek all kinds of havoc on an entire operation and such vulnerability should be obvious to the manufacturer. Still, for somebody with one switch in a noncritical application will find that they work very well.
