Abstract
Disclosed is a motion detection switch, and more particularly a motion detection switch which can recognize motion of a reflector moved at an upper side of a display part of a mobile phone, and can control the mobile phone without any touching operation. The motion detection switch recognizes motion of a reflection body moved at an upper side of a display part of a portable terminal and controls the portable terminal, including a base which is disposed at an upper side of a main body of the portable terminal having the display part, which is outside the display part; a light receiving device which is disposed at the base; a plurality of light emitting devices which are disposed at the base so as to be symmetric with respect to the light receiving device; and a control device which operates the light emitting devices.
