another question, my relay  with two-contacts is working on certain polarity then not work on the reverse polarity (i mean to the coil of relay), i didn't know about polarity-dependent relay, is that really happens?

please , i need some comments about that!

thanks for your reply.I've searched previously for the datasheet of my relay and couldn't find it, i might not detect the right type in search field....

i can note  some writings on my relay:
NAiS
JW2SN
-DC12V
AJW7211
made in thailand

does that help?!

Your relay is made by Panasonic. It is a 12 VDC / 5A relay. Here is a link to the data sheet that will help you understand the markings on the case and what they mean.

That is not actually true. The first step is to check the data sheet for the relay you are using. If you are using a 5 volt relay with a 6 volt maximum allowed, you are slowly killing the relay by using 6 volts. You also have the worry of surges on the circuit causing the voltage to fluctuate. In this case, you would see a premature failure of the relay when the voltage passes the max rating. The only reason that a circuit might appear that you need more voltage than specified of the relay is if you are asking for too much current through your relay. Then there is a voltage drop. In this case, the correct solution is to get a relay that will handle the current required and stay with the correct voltage rating.
