Abstract

PURPOSE:To enable to perform minute phase control of a TRIAC for dimmer, etc., by a method wherein switches to be made to ON condition by touch electrodes are arranged in one line, and the trigger phase angle is set by output corresponding to one switch out of the switches made in ON condition. CONSTITUTION:The switches I of the plural number to be made to ON condition by the touch electrodes 20 are provided being arranged in one line, outputs thereof are inputted in converter circuits C0 through capacitors C, resistors R, and buffer circuits B, outputs thereof and outputs obtained through inverters IN are applied to NAND circuits N to obtain output O having the value corresponding to one limited switch out of the switches made in ON condition, and setting of the trigger angle of the TRIAC for a dimming circuit, etc., is performed. Accordingly the desired brightness can be obtained immediately and brightness can be made to vary gradually by making a finger to touch the touch electrodes 20 and making the finger to shift, and extremely minute control can be performed.
