2.7 - Toggle Left and Right

img_slide

The slide switch is a 3-pin device, with pin 2 (middle) being the common pin. When the switch is toggled to the left, the left two pins are connected together, and when toggled to the right, the right two pins are connected together.

Schematic

GP14 will get a different level, when you toggle the slide switch to the right or left.

The purpose of the 10K resistor is to keep the GP14 low during toggling (not toggling to the far left and not toggling to the far right).

The 104 ceramic capacitor is used here to eliminate jitter.
