Abstract: A switching operation sensing apparatus includes an input operation unit, an oscillation circuit, a frequency digital converter, and a touch detection circuit. The input operation unit includes a first switching member integrally formed with a housing. The oscillation circuit is configured to generate an oscillation signal having a resonant frequency, varying based on a capacitive change or an inductive change, depending on a touch input member in contact with the first switching member during an input operation. The frequency digital converter is configured to convert the oscillation signal into a count value. The touch detection circuit is configured to detect capacitive sensing and inductive sensing based on a slope change of the count value received from the frequency digital converter, and output corresponding touch detection signals of different levels based on the detection.
