1. A flushing switch device with automatic pressing stroke detection for pressing two flushing switches of a toilet, wherein the two flushing switches respectively correspond to different flushing amounts of water, and the flushing switch device with automatic pressing stroke detection comprises:
a capacitive sensor, configured to sense a user's hand movements to generate a sensing signal;
a actuator, comprising a driver and a pressing mechanism, the driver configured to drive the pressing mechanism to press one of the flushing switches; and
a protector, configured to be electrically connected to the capacitive sensor and the actuator, the protector comprising a detector and a controller, the detector detecting a load variation during an operation of the actuator to generate a detection signal, the controller receiving the sensing signal and correspondingly generating a control signal to control the actuator according to the sensing signal and the detection signal.
