This study investigates the event‐triggered adaptive switching stabilisation problem for a class of lower‐triangular non‐linear systems with multiple unknown control directions. A novel Lyapunov‐based event‐triggered adaptive switching control rule is proposed to implement the stability of the closed‐loop system. Moreover, a unified time sequence is introduced by combining two time sequences which are generated from such a control rule. The designed event‐triggered adaptive switching controller not only ensures the closed‐loop systems is globally generalised exponentially stable but also excludes the Zeno behaviour under the triggering condition. Finally, two simulation examples are provided to illustrate the effectiveness of the proposed control strategy.
