I got exact same yesterday, had it for 20 minutes before frying it, never been great with electronics, looking for a self latching version too, Thom in Scotland.

Bummer! Tricky finding actual latching relays. I don't know why. It's much better than having to keep a relay powered all the time. You'd think they'd be more common and better labeled.

Lol, yea, I watched video by, EHobby. Called, How to create and wire a relay to latch ! ! , very intresting, tho i might avoid actually building one ! Lol. , Thom

WOW! Does this really use an STC micro-controller just to latch a relay? Talk about using a sledgehammer to crack a nut.....wouldn't a 555 do the same thing? Whatever.....thanks for the video, always appreciated.

Guess so. It's definitely a pretty pointless module if a latching relay is needed. But, I was able to make a video with it. Hopefully I can prevent others just starting to learn things from wasting their money on deceptive components. Thanks for watching!

I don't think this is out to deceive anyone, in fact it simplifies things considerably when you need a latching relay....the test button provides a simple push-on push-off solution with the option to use your own 'external' switch with that plug/wire that you show. Were you to replicate this with just a dedicated 'latching' relay you would need two buttons, one for 'on' and one for 'off'......here the micro-controller is simplifying it by just using the one button....although you yourself have already demonstrated that you don't need a micro-controller just to do that.

Strange relay. You sure it's not damaged? That current draw kinda looks like it may be malfunctioning.
@Electronzap5 жыл бұрын
Maybe. Could just be a poor design. I just started using relays, so I still have a lot to learn.

@@Electronzap it's got a lot of parts on it that's for sure. It's kinda odd that it draws different amounts of current. My instinct says they should be equal.

I'm pretty sure the relay doesn't actually latch, even though it is sold as a latching relay. But, instead the module holds it in the on position with current. I'm looking for a better one that is decently priced to compare it with.

@@Electronzap the latching part can be acheived by the way you wire a regular relay. You can make a regular relay latch if it is the same voltage as the voltage used in the rest of the circuit. Or you can add a low voltage transformer. Check out latching wiring diagrams in HVAC (heating and air) stuff.

did you finally find a REAL bistable latching relay? I got this one(like in your video) today and another one both advertised as bistable on aliexpress and both draw around 60mA... what the heck... any idea where I can get a latching relay and not these useless fakes.

I actually found one in an old "Make Electronics" kit I have. I never found any that I would buy so far unless I absolutely had to.

@@Electronzap I have a TP223 touch sensor that I want to control the 230V input of a 750W psu, will this sort of relay work or it will fry it? (tp223 is configured to give a low latching signal, but can be configured to give high signal too)
