Abstract
A switching operation sensing device is provided. The device includes a touch operation unit that is integrally formed with a housing and includes first and second touch members disposed in different regions; an oscillator circuit configured to generate a first oscillation signal including a variable resonant frequency when the first touch member is touched and a second oscillation signal including a variable resonant frequency when the second touch member is touched; and a touch detector circuit configured to detect whether at least one of the first and second touch members has been touched, and distinguish touch regions based on the first oscillation signal and the second oscillation signal.
