Q about Weapon Swap

Can a staff weaver use a sigil that applies something on weapon swap? If so, what triggers the effect?

Attunement swapping, picking up conjured weapons, dismounting, and anything else that changes what appears in the ele's hands.

Changing attunement triggers weapon swap sigils, I think both for half- and full attunement on weaver. Keep in mind the internal cooldowns on such effects though,

Thanks. I've been avoiding those sigils.
