Check with meter that contacts are like supposed in contact side. It could be just bad part, relay has already seen use, contacts sometimes ''lock'' or more to say melt together rarely. Then relay tries to operate but already has operated, it can be fixed by opening relay and carefully prying and smoothing contacts. But low voltage/current for coil is main issue that causes relay not work (again oldie....)</p>

I'm designing a PCB and simply want to be sure the polarity is not an issue.</p>

Sam Zimmer on COM-10924 - Relay SPDT Sealed - 20ASam Zimmerurn:uuid:0e487e7b-7caa-ee03-1409-c91e83bcc4962014-04-13T20:23:18-06:00<p>I would like to use this in a three-way switch system, is there a way to accomplish this or should i get a different relay? What is the purpose of the other pin not used on the control board?
Update:
I finally got a continuity test from NC to COM, there was some stuff covering the pins blocking the signal</p>

I'm thinking of building a railgun, which involves a lot of very big capacitors (on the order of 300v) going off in parallel, and I need something with which to switch them. Will this do the job?<p>EDIT: Nevermind, the datasheet says 28v, which is less than 1/10 of what I need. I'll keep looking.</p></p>

The relay in the tutorial is pictured with a control board containing resistor, LED, etc. Does Sparkfun sell this item with the board? Or do I have to buy that somewhere else?</p>

The Arduino activates the transistor, the transistor activates the relay. See the <a href="https://www.sparkfun.com/tutorials/119" rel="nofollow">Relay Tutorial</a> to see exactly how this is accomplished.</p>

It says power consumption is 0.9W @ 5.0V, that's 180mA, which exceeds the current capability of an Arduino port.</p>

Almost like they planed for them to be used with an arduino. The data sheet is somewhat confusing because it cover many relays of this type.</p>

Getting the most safety and performance requires a knowledge of high-powered PCB and/or Breadboard design techniques. If you know what you're doing, that's great- but if, for instance, you are unfamiliar with the concept of creepage, or selecting the right gauge wire for an application, you can get into some trouble.<p>I think that a much more hobby-friendly device is something like this:
http://www.mouser.com/Search/ProductDetail.aspx?R=T9AP1D52-12virtualkey65500000virtualkey655-T9AP1D52-12
This one is literally only a few cents more, and electrially identical, but use Faston connectors instead of PCB pins.<br>
When it comes to building high-current/high-voltage circuits, point-to-point wiring is easier and safer to do with the tools available to the average hobbyist. I cringe when I see photos of kludgey-looking projects controlling things like heaters and air conditioners with sloppy and inadequate wiring and connections.
Please consider offering a different version.</p></p>

I checked the data sheet, but it describes a range of relays with coil voltages from 5VDC to 110VDC depending on the part number, and I don't see a number in the pictures that look like it matches the datasheet.</p>
