Abstract: A flushing switch device with automatic pressing stroke detection is provided, which is applied to the flushing switches of a toilet. The flushing switch device with automatic pressing stroke detection includes a capacitive sensor, an actuator, and a protector. The capacitive sensor senses a user's hand movements to generate a sensing signal. The actuator includes a driver and a pressing mechanism; the driver drives the pressing mechanism to press one of the flushing switches. The protector includes a detector and a controller; the detector detects a load variation during an operation of the actuator to generate a detection signal; the controller receives the sensing signal and correspondingly generates a control signal to control the actuator according to the sensing signal and the detection signal.

Abstract: An optical sheet having an adhesive layer is wrapped by a first packaging component of which the material includes a plastic base mixed with silicone. A second packaging component then wraps the first packaging component, and the second packaging component is opaque. The plastic base can be polyethylene or polyethylene terephthalate, and the weight percent of the silicone to the plastic base is less than 5, preferably less than 3.
