 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,
I'm working with the Relay example and I'm turning on/off a Fan that works with 220V. It works find. My question is which is the setup that I need if i want to connect 10 Fans (220V) controlled by one relay.
I will connect them in parallel but I don't have clear the circuit to protect all the stuff.
Thanks a lot for the help

You just need a reverse diode across the relay coil. If you like you could put a 0.1uF capacitor across the relay contacts to stop arcing.
