Document Type and Number:
WIPO Patent Application WO/2010/035936
Kind Code:
A1
Abstract:
The present invention provides a capacitive switch for a cosmetic treatment apparatus and a switching method using same. The cosmetic treatment apparatus according to the present invention has a switch unit, a part of which is constituted by a capacitive switch (10). The capacitive switch (10) comprises a continuous contact plate (11) which is constituted by at least three switch indication parts (14) disposed along the common range of the movement of the finger of a user, and which functions as a dielectric plate, spring electrodes (12) the tops of which are elastically installed beneath the switch indication parts (14) of the continuous contact plate (11) and the bottoms of which are installed to contact the terminal of a sensor IC (13), and a micro computer (20) which recognizes sensed values of the sensor IC (13) to determine the operating state of the switch. The continuous contact plate (11) having the switch indication parts (14) is formed into a C-shaped protruded line (15) which can be easily touched by the finger of the user.
