I am working on a new project and one of the items that I need is this:
However, I live in Canada so I cannot purchase it. I was wondering if someone could help me find another part that would be similar to this? I was thinking of using Digikey.ca to find the part. I have never used a relay before so I tried my best with the filters... I first filtered it down to what can be found in this link: http://www.digikey.ca/product-search/en/relays/signal-relays-up-to-2-amps/1049448?k=relay
Then I filtered the Coil Voltage to be 5V and Contact Form to be SPDT (1 Form C). In the radioshack link it says 90mA but I was not sure if that is referring to the Coil Current or the Contact Rating (current). Also, the switching voltage should be 125VAC but then on Digikey there are options for the max DC Voltage as well and I am not sure which one to choose.
For those interested in what project I am doing you can find it here:
The first link looks good but then I am also buying other parts on Digikey so it would be ideal to get it off Digikey to save shipping. Or does Digikey have nothing similar?
Thanks for the second link, I might actually do that as it seems pretty simple, I might try both ways because I also want to learn how to use a relay :P.
A snubbing diode is needed if the load is inductive like a relay, solenoid or motor. Flyback diode - Wikipedia
I've never heard of snubbing diode, only a snubber circuit, the flyback diode is to supress the magnetic field when it collapses which is placed backwards with the relay and your circuit.. however this is low voltage don't forget when the metal contacts make contact the inductive load like a fluro, motors....
Those kinds of applications the mains 240v side of the relay a snubber circuit is a capcitor and resistor across the relay contacts...
So are you saying to use a flyback a didode across the contacts?

"A flyback diode (sometimes called a snubber diode, freewheeling diode, suppressor diode, suppression diode, clamp diode or catch diode[1]) is a diode used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply voltage is suddenly reduced or removed."
