1, Simplified design: In order to pursue simple appearance and more convenient operation, Galanz chose to integrate the switch function into other control buttons or realize the switch function through an intelligent control system.

2. Safety considerations: The microwave oven needs a safety protection mechanism to prevent users from accidentally opening the oven door or starting the microwave oven during operation. Therefore, Galanz believes that there is no separate switch to ensure the safety of users.

3. Standardized design: The design of microwave ovens usually follows some industry standards and practices. Perhaps in Galanz's design, no single switch is part of these standards.
