Hi Guys,
Just a quick sanity check,
If I wanted to PCB Mount a relay to switch 230V AC @ 16A Max, I have calculated that I would need a 9mm trace, so I have provisioned 10mm, but the trace is huge and I was wondering if that little legged relay can switch such a high current (it would probably be more like 10A max for most AC appliances, 16A is the relays max rating), if I had a pad next to the relay leg and put a trace the size of the pad to link them could I use 16/02 wire to link the power supply to the relay poles?
Would this be a better option?
I've switched a 3.5A Laptop PSU (3.42A to be precise) using a small-ish trace and it hasn't overheated or been damaged, and the circuit is still working 2 years later with no probs, so I just wanted to get someone who has done this kind of thing before's opinion.
Also, what would be really handy if someone could knock up a quick PCB design in Eagle demonstrating track widths and pad sizes for a standard sized 12V switching relay.
As I am fairly new to Eagle it would be good to get a visual representation.
Many Thanks
Wilksey
