LARGE SIZE AREA TOUCH SWITCH TO USED OF PIEZO SENSOR

摘要

PURPOSE: A large size area touch switch is provided to reduce electricity by installing an illuminance sensor defining a day and a night. CONSTITUTION: A touch(10) is installed on the wall. A delivery plate(50) evenly transfers an external pressure applied to the touch unit. A piezoelectric sensor(60) changes the pressure added to the delivery plate into the electric signal. A controller(40) is connected to the piezoelectric sensor. The controller transmits a control signal according to the signal of the piezoelectric sensor. An operating unit is connected to the controller. An LED part(70) is connected to the controller. The LED part is turned when the operating unit is in standby. The LED part is turned off when the operating unit is operated. A power supply unit is connected to the controller.
