#08-040 Demo a 12 Volt 30 Amp Relay Test Setup

[jeancruz01]

Why most people say that a relay can amplify current? i don't understand them!!! A relay acts only a switch and the 30AMP rated in the relay is the amount of current a relay can handle. Just like a fuse, a 5AMP fuse, if you run this fuse more than a 5AMP it will Damaged.

you can direct it.no need relay. just a switch.hehe

Junk Science!

I did this exact experiment at school. He did a number of things wrong. I'll give e-props to anyone who knows how the lead need set up...and how to do the basic relay test.

That relay is useless. You use a switch to turn iti on and off, you could/should skip the relay and just use the switch!

What are yu trying to do anyway, you seem lost in the details.

[skierplaterandy]

the relay has a max current of *30 AMPS!*

the switch is probly like 2.

you can put way more thru the relay than the switch

Sorry but no you are wrong. That seems to be a "Sierra Heavy-Duty Toggle Switch" that is rated for 50 amps continuous.

I don't mean to bicker but i just wanted to help him out considering his own admitted lack of experience in the area.

Along that line I hope is doing alright; no new posts for over a year. The stuff he was hobbying with can be very dangerous.

well, from the sound of the curcuit, it seems that the relay is switching on and off continuously. that cant be done with a switch.

and most switches aren't that high, and even if it is, its just a different way to do something.
