This　paper　studies　the　bumpless　transfer　(BT)　control　issue　for　switched　systems　with　event-　triggered　(ET)　control　input.　The　aim　is　to　reduce　the　jumps　in　control　input　at　both　switching　and　triggering　points,　while　capturing　the　stability　of　the　switched　systems.　First,　a　dynamic　ET　program　is　constructed　with　the　triggering　condition　based　on　the　level　of　suppression　of　input　signal　jumps.　This　not　only　reduces　input　jumps　at　triggering　points,　but　also　prevents　Zeno　behavior　caused　by　triggering　within　the　operation　time　interval　of　subsystems.　Second,　a　sampled　state-dependent　switching　signal　is　designed　to　ensure　a　dwell　time　for　subsystems　to　prevent　Zeno　phenomenon　induced　by　switching.　Further,　a　switched　ET　controller　with　alleviated　jumps　is　designed.　Third,　conditions　are　obtained　to　simultaneously　reach　both　stabilization　and　BT　of　switched　systems.　Finally,　the　effectiveness　of　the　theoretical　results　is　demonstrated　through　a　simulation　of　an　engine　model.
