SWITCHING UNIT FOR DETECTING SPACIAL CONTROLLING MOTION

摘要

PURPOSE: A switch device is provided to implement various functions through one switch device by generating various electric signals according to the change of the current of a light receiving unit due to the movement of a reflector. CONSTITUTION: A housing(100) is combined with an optical pad(400) to transmit light. A light emitting unit(E) is arranged in the housing and emits light to pass through the optical pad. A light receiving unit(D) is arranged in the housing to generate a current by receiving light reflected by a reflector outside the optical pad. A controller controls the operation of the light emitting unit and the light receiving unit. The controller generates an electric signal according to the change of the current of the light receiving unit.
