Touch spring, also known as induction springs, are dedicated touch buttons that are dedicated to capacitive and single-chip touch chip solutions. The touch button detects the change of the capacitance caused by the human touch through the charging/discharging time of the resistance-capacitance network formed by the capacitance CX of the resistor and the sensing electrode, thereby detecting the state of the control button and realizing the functions of the touch button. These micro springs are widely used in a range of consumer electronics, black and white, white electricity, kitchen appliances, and other products.
