PMR209 Snubber
Devantech
The PMR209 provides arc suppression for switching inductive AC loads on relays. The snubber can be simply wired across the common and switched contact to stop the spark, providing extended relay life and reliability.

Need for RC snubbers across relay outputs
Inductive loads generate voltage spikes when switched, the collapsing magnetic field creates high energy voltage spikes that can get coupled into the low voltage areas on circuitry causing erratic behavior or even crashing the CPU. Adding an RC snubber absorbs the energy created when switching the device off. The snubber also has a secondary benefit of prolonging relay life for inductive loads as it arrests the arc that is generated when switching off.
Examples of inductive loads that need an RC snubber would be:
Motors
Solenoids
Relays (where the coil is driven as a load from the first relay)
