PURPOSE: A capacitance type accelerating button assembly is provided to improve user convenience by performing elasticity and restoration processes of a button while changing capacitance successively. CONSTITUTION: In a capacitance type accelerating button assembly, a supporting plate(10) forms a first through-hole(11) at a center point. A ground plate(20) has second through-hole(21) at the center point. A spindle type coil spring(30) is wider in an upper part. A button(40) forms a protrusion(41) in the lower perimeter and a protrusion which is inserted into first and second through-holes. A touch pad(50) generates an acceleration signal by detecting capacitance.
