一种电子设备，其包括触摸感应开关。触摸感应开关包括至少一射频传感组件、至少一声波式触摸传感组件及控制模块，至少一射频传感组件和至少一声波式触摸传感组件分别与控制模块通信连接，射频传感组件用于传感接触面的触摸物的轮廓，并将轮廓信息输出至控制模块，控制模块用于根据轮廓信息进行处理分析，并进一步根据分析结果输出不启动或启动声波式触摸传感组件的指令，声波式触摸传感组件用于传感接触面的触摸按压动作，并输出一表征触摸感应开关被触发的触摸信息。

This disclosure relates to an electric device including a switch. The switch includes at least one radio frequency (RF) sensor module, at least one acoustic wave touch sensor module and a control module. The at least one RF sensor module and the at least one acoustic wave touch sensor module are connected to the control module to communicate with the control module, respectively. The RF Sensor module is configured to sense a contour of a touch object on a contact surface and output the information of the contour to the control module. The control module is configured to analyze the contour information, and further output an instruction whether or not power on the acoustic wave touch sensor according to the analysis result. The acoustic wave touch sensor module is configured to sense touching and pressing on the contact surface and output a touch information representing that the switch is triggered.
