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

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.

Although the product ships without documentation, it's easy to download and print what you need. Very versatile board, and it does exactly what it says it will do. As a bonus, the terminals are big enough to squeeze two 16AWG wires into!

This is a well built and well documented board that I really appreciate being offered here. I've already planned including it in a future project that I'll be working on in the next couple of months.

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.

Solved my problem of triggering a 12v relay in a car with a micro switch . Happy I found these guys

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

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. Thanks AU //(~_~)\\
