This article provides guidelines for designing a self-capacitance slider. A suitable design should be chosen based on the width requirements of the slider. This slider design should be used when using Atmel START-based QTouch® Modular Library.

When using the Microchip Studio-based QTouch library, the slider design guidelines provided in "Section 5" of the " Capacitive Touch Sensor Design Guide" should be used. For mutual capacitance slider design, refer to "Section 6" of the " Capacitive Touch Sensor Design Guide".

Note: The Y line numbers indicated in the images represent the order only and NOT the actual PTC Y lines. The PTC Y line can be connected in any order.
