Claim 31:
32. The electronic device of claim 31, wherein the touch switch unit further comprises a second touch member that is a portion of the non-conductive cover and a second force member that is a portion of the frame, and
the touch sensing device further comprises:
a second touch sensing unit disposed inside the electronic device and comprising a second sensing electrode and a second sensing coil electrically connected to each other, the second sensing electrode being disposed near the second touch member, the second touch sensing unit having a capacitance that changes in response to a human body pressing the second touch member according to a parasitic capacitance generated between the second sensing electrode, the second touch member, and the human body by the human body pressing the second touch member; and
a second force sensing unit comprising the second sensing coil, the second sensing coil being spaced apart from an inner surface of the second force member by a gap, the second sensing coil having an inductance that changes in response to a human body pressing the second force member according to a change in the gap between the second sensing coil and the inner surface of the second force member caused by the human body pressing the second force member.
