Note: As good engineering practice, it is ALWAYS a good idea to put a
snubber diode across and inductive (relay) load to prevent the unwanted
transmission of spikes into the air and or circuit not just to prevent a
damaging inductive spike. This diode must be placed as close to the relay as
possible. Any lead length or circuit trace longer than an inch will always
radiate somewhere in the RF spectrum and may cause interference.
