Some solenoids and relays have a built-in diode (check the datasheet) that acts as a snubber to prevent chatter when the coil's magnetic field collapses.

There's a with/without diode comparison demonstration from 9:15 - 10:00 in this video.


If there's no built-in snubber and you have a problem with chatter, add a diode.
