Hi guys,
Computer newbie here so hi to everyone.
I've built myself a power supply from an old PC PSU so I have 3 output voltages which all works great. I'm just learning about relays and other components. My question is regarding the following relay circuits diagram.
I understand that when I put 12 volts on the coil a magnetic field is generated and operates the switch, which is normally open.
However I have for pins on the bottom and two on the top, the to bring for the secondary circuit. And two of the bottom four for the coil. But I can't figure out what the other two pins do on the bottom ?
Could someone explain in simple terms.
