BWSS 12V 433Mhz DC 3.7V 5V 6V 7V 9V 12V Remote Control Mini Relay Wireless Switch Secure 1-Channel Micro Receiver with Transmitter System

Good value

I used this remote relay switch to activate a 4.5 volt (3AA batteries) decoy. It would not activate on less than 6 volts of incoming power though. The relay would "click" but power would not pass through to make the decoy run. So if you're looking to use this on a project using less than 6 volts, I do not recommend this one. I wired it up as per the diagram that is included. There are 3 different diagrams depending on what you want it to do. Make sure you choose the right one. Range is just ok. 4 stars.

The instructions that come with the switch are useless. But the switch does work once you figure out how to wire it.I used the switch with 3 D cell batteries in series, 4.5VDC, to light LED lights.I connected the neg from the batteries to the neg black wire on the switch and the neg side of the LED bulb, all the negative wires together.The positive from the batteries and the red and blue from the switch together.The positive side of the LED bulb and the yellow wire from the switch together.The switches come latched and are extremely difficult to change to momentary, unless you really good with a soldering iron and have an extremely powerfully magnifying glass. There are other momentary switches available.

As per item description, it supposed to have Normally Open, and Normally Closed options, But it doesn't have NC at all ( No wire left for NC).If somebody have an application for NC, shouldn't buy this product.

I used this to create a remote push to talk switch for my paragliding harness. Works great and weighs almost nothing. it is a dedicated 433 mHz coded signal, so no mucking around trying to repeatedly pair remote and switch, as with some bluetooth devices. The switch is about the size of half of my little finger (medium-small hands). The remote fob that comes with it is bigger than the switch. Powered by a 9V battery, the switch will draw about 6 mA at idle, and about 30 mA when triggered, and last about a week if triggered about 1-2 minutes per day.The switch can easily and quickly be trained to pair with some other 433 mHz remote transmitters, although the instructions are a bit unclear.Since my application requires only low currrent switching, I would have preferred an optocoupler instead of a relay for switching, both for efficiency and reliability.
