12V 12 Volt 30/40A Automotive Relay with Socket 30 amp / 40 amp Relay
A part of the review has been auto-translated.
Please be aware that fourth pin allows current when control lead is off. When control lead is on, the fourth pin {output) blocks the current. For the matter of fact, it wa kinda described as that on the scheme above, but I overlooked, expecting it to work vice versa. I can't use this relay for e.eg. fog lights, since relay switches the lights off when engine is ignited, and switches the lithe ligthts back on when engine is stopped, which is pretty useless. I wiil have to buy another relay with five pins.
This is NOT the relay you want for switching 12v loads ON. It is normally ON and when power is applied, it switches the relay connections OFF. It is NOT for horns, headlights and things that are normally OFF. The quality and price are fine; just make sure it's what your application needs.
great stuff , We will not boycot Asia !!!! regards from Europe.
Perfecto

Podrian adjuntar un pequeño esquema para quien no sepa de electronica
I use these in my charge controllers for my solar panels.
I was doubting that my parcel won't arrive on time, but today I just received a phone call from the Post Office that they have a parcel for me. I thought it was one i ordered from the United States which I ordered first before this one. But to my surprise I found that its the one I ordered from you which arrived. To say the truth, I wasn't expecting it. Thank you for the good service and you should continue working like this. Am looking forward to making another order.
wiring info would be beneficial
no instructions. wiring diagram seems to conflict with colour coding of the wires. I assumed green was (-) yellow(+) load and white (+) signal. but i'm not certain.!!
