HEH!! I must say, I was very dissappointed when I hit the switch and nothing happened lol

 

Well haven't looked at Dewey's too hard but do agree that getting the 12V switched is safer.

 

Is pin 85 and pin 86 interchangable? One of this drawings has 85 for ground the other has 86 as ground.



BTW, I am not trying to be difficult, I am trying to understand this and learn, lol.

 

Pin 85 and 86 polarity doesn't matter. Those are the pins that feed the relay coil. As long as you have + on one and - on the other your are good to go. Same goes for 87 and 30 except this is the switch/contact side.

 

Okay. A relay allows a low amp circuit to control a high am circuit. That is the definition.

Pin 30 is the power 12V that is going to make the circuit work.
Pin 87a in this case is nothing.
Pin 87 is going to be what turns the solenoid on.
Pin 85 is going to have a 12V going to it.
Pin 86 is going to be the ground (switch controlled) that will energize the coil inside the relay and allow the pole in the relay to switch from 87a to 87.

To answer your question about 85 and 86 they can be switched, there is just a coil between them that is energized when power is allowed to flow through them.

Everyone drew a picture, here is mine.


(i hope this helped in your learning )

So 30 AND 85 need 12v power?

 

Yes. I added a picture to my post before, I am not 100% on the activation switch, but i think you can figure that out.

How about I get rid of the damn relay and do this?

 

yeah, i would think so but i don't recommend it. The Relay way allows you to, like i said before, Control a high amp circuit (solenoids) with the low amp circuit (very little power to light up a activation switch light).

Solenoids pull way to many amps to not use a relay. Unless you want to run wire the size of your middle finger along with an industrial size arming switch and pushbutton.
