This paper proposes an observer-based resilient switching-like event-triggered mechanism for networked switched systems under denial-of-service (DoS) attacks and deception attacks. First, an observer is constructed to estimate the system states, and an observer-based event-triggered mechanism is designed. Second, the triggering parameters are dynamically adjusted by determining the DoS attack status using an acknowledgement character (ACK) mechanism. This approach effectively compensates for data loss induced by DoS attacks while significantly reducing the communication load. Unlike existing approaches, the proposed method systematically addresses simultaneous DoS attacks and deception attacks on communication channels, thus ensuring robustness in multi-attack scenarios. By constructing a mode-dependent Lyapunov-Krasovskii function, rigorous quantitative constraints are established between subsystem switching dwell times and event-triggered intervals. These analytical foundations enable the derivation of sufficient conditions for the exponential stability of closed-loop systems, along with explicit controller gain solutions. The proposed framework integrates a switching-like event-triggered mechanism with switched system theory, thereby resolving the asynchronous switching issues caused by the attack-induced packet dropouts. Numerical simulations verify the validity of the proposed theory.
