I have a 5v dc output connected to an indicator LED that is active when i need it de-activated. visa-versa it turns off (deactivated) when i want the LED to light. I need the current draw to be as low as a LED draw, i think a relay with draw too much current?.. i was looking at this relay, the control would be input but what is pin 3 N/C (normally closed) ....thankyou
