Electronics relays

What type of relay is this? SPNO ?
The same as http://www.maplin.co.uk/Module.aspx?...rce=14&doy=6m1 ?
Went into Maplin today and asked for one, and they have supplied me with this, which im fairly sure is the wrong one (SPCO). Foolishly i didnt bother checking untill i got home (Was in a rush).

Going from the picture above – once the correct trigger voltage has gone into the relay at the top left, the switch on the right would close? Correct?

I was fairly sure I knew what type of relay it was until I went into Maplin. Either my memory of electronics is failing me (its been a long time), or they have messed up. Either are feasible

Cheers

that diagram looks like spno yeah, a spco will work, it will have 3 terminals instead of 2, so just pick the one that makes it operate spno

That’s what im planning to do buddy, just a bit gutted that i paid over a fiver for it when i could have picked one up for a couple of quid. Typical Maplin's for ya.

Really wanted a second opinion though, its been a while. Cheers

Dare I ask the crazy project this will end up in?

Yeah, that's what i'm wondering as well. What project will this Electronic Relay be featured in? I'm hoping a computer forum because that will be the most interesting for us (I hope I speak for the rest of the forum when I say that).

To be fair to the guys that work there, you either get students who know what theyre talking about, but are run off their feet (like me when i worked there) Or lifers with no trainging whatsoever. I literally never had one bit of technical training for the 2 years i worked there, and id say there were probably 3 other guys out of a staff of 20 that knew anything about components.

Afraid not. Its going to be for some changes im doing on my motorbike. This is for the Alarm system that im beefing up

I wasnt blaming the guys. They do there best and thats all I can ask for. I blame the big multinationals that wont invest in their staff.
Belive me, I worked at game for 4 years, I know the kinda people that get employed.

Adding rail-guns? Active camo? Automated tear-gas release system?!

It depends, did you specifically ask for a relay that could switch 40A?

You should send that in to the Head office, im sure theyd love to be described as a big multinational, theyre the biggest bunch of cowboys going. My manager couldnt even tell you why you shouldnt use 10A mains cable to wire in a cooker.

And why would you expect the store manager to know that, Maplins sells a lot of diverse stuff, I'm sure you can't expect the staff to be experts on each and every item.

[herulach]

Well, for a start because this guy claimed to have an electonics degree. But also because he was selling it to someone for that purpose. Im sure when the guys house had burnt down, 'well you cant expect everyone to know everything' would be a comfort.

10A mains for a cooker??

That's just scarey.

[Whiternoise]

How high would it need to be for a cooker?

I would have guessed 30A.. but there you go..
