Weapon swapping sigils and Elementalist

My question is, do weapon swapping sigils still work for Ele's based off swapping attunements? Or do they not work at all on characters like Elementalists or Engi's cause they have not secondary weapon set?

Yes, every time you change attunements (ele) or swap kits (engie), the sigils can trigger, within the limitations of their cooldowns. This also happens when you pick up bundles (e.g. Ele conjure weapons or any environmental weapons found on the ground).

PS this information is on the wiki, e.g. the "on swap" section of the Sigil article

And, I think, they also trigger when you use a mount’s engage ability.

Which is kinda funny, and useful.
