PROBLEM TO BE SOLVED: To provide a touch type knob switch that enables turning on/off of an external power supply or gradual adjustment for a power feeding magnitude on the basis of a revolution route by a touch system.SOLUTION: In a touch type knob switch, a sensor surface is provided to an upper part of a housing, and a touch control circuit board is installed in the housing. A touch control circuit layer provided on an upper surface of the touch control circuit board is divided into a plurality of sensor areas. A plurality of first light-emitting elements are annularly arranged and installed in the sensor areas of the touch control circuit layer, and the touch control circuit layers of the sensor areas are sequentially triggered by being touched by a user along the sensor surface. The touch control circuit layer of the triggered sensor area controls light emission of the first light-emitting element corresponding to the triggered sensor area, and outputs an encoding signal for controlling power feeding of an external power supply on the basis of the triggered sensor area. Thereby, convenience for use, durability, and use-life are improved. |
