a slide trigger is a lever on first and third valve slides to rapidly extend the slide for the correction of intonation. The triggers are spring loaded so operation (and return) of the mobile slides is virtually instantaneous.

Triggers are not usually deemed neccesary on most trumpets but on cornets in British brass bands (where they originated) they are vital for contesting at the higher levels as test pieces are often written with purposful traps for unwary cornet sections and adjudicators listen closely for intonation even in running quaver passages.
