Default Relay contacts sticking

Relays used to switch inductive loads, such as your pump motor, are prone to
arcing when they switch on and off. This is quite normal, and unless some
sort of arc suppression (snubber circuit) has been used across the contacts,
they will eventually fail.


Can I buy a snubber somewhere? Can I build one with a few parts from
RadioShack?

BTW, it seems most people switch their pumps with a pressure switch (as
opposed to a relay), and I've never seen a snubber on a pressure
switch.
