Here is a start on snubbers : https://en.wikipedia.org/wiki/Snubber with
link to https://en.wikipedia.org/wiki/Arc_suppression
For a mains application an X rated 0.1uF cap in series with 100R 1W
resistor might be a good start (across contacts which need protection).
This is for a slightly inductive load. Ambiguity indicates uncertainty,
as in most cases...
Anyone got any better rules-of-thumb on the subject ?
