ELECTRONICS-SALON Panel Mount Momentary-Switch/Pulse-Signal Control Latching SPDT Relay Module,12V

Used this for a stop and start button on a portable pt01 scratch turntable. It's overkill for a momentary button but I don't want to wait over a month for a part. With prime you can get this in a few days vs waiting for it coming from China. But if you have the time and patience then by all means order the other part over seas.Delivered on time.Instructions on what connections to use for a momentary start / stop button were easy to follow. It works as intended.

I use this to control an air compressor and air valve in my shop. I can cycle the air compressor ON/OFF with the large red button. I also connected it to a wireless remote system. I have transmitters around my shop so I can use them to turn the air compressor ON/OFF from several locations. Power for both comes from a 12V power supply. Each remote transmitter has its own battery.

I like the separate set/reset inputs along with the pulsing input or toggle. It works well and seems well built and simple. Through-hole design can be repaired by the hobbyist.

With a very simple change to the design, the device could be used from 9.5 v to 30v. (move one resister connection to the controlled voltage area). Turns out, the easy power access i have is 24v, but i got the 12v. so now i need the higher volt device.

Initially I was having issues with this relay randomly changing state. I had to add a sensor to measure if the load was on or off every 5 minutes and used a script to tell me when the relay would change state.. which was in fact happening 1-2 times per day. So I instructed the script to ensure the relay was in its desired state throughout the day. Its been running a few months now and the randoms state changes have settled down, but still happens sometimes.

Set/rst works but the relay won't engage. I think there is a short in the board because it gets very hot

Car alarm place who installed new fog lights on my Murano suggested I buy this board so I could use a factory Nissan switch to trigger the after market fog lights he installed. So far it has worked like a charm. Love the fact I was able to download a pdf sheet showing how to setup board for desired installation. Very happy. Will update as time permits.

I was building a water control device for a client and needed a latching relay.While I didn't feel that this component was heavy duty enough for my needs, I do think it is a real handy control circuit for smaller projects.Circuitry seems good, individual components are fine, and figuring out how to work it was not difficult.All in all, a pretty good little circuit. Just don't expect it to operate a large motor or water pump.ThanksAU//(~_~)\\
