A potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value. They can be attuned from zero ohms to whatever maximum resistance that is specific to it. For example, a potentiometer of 10 kΩ can be adjusted from 0 Ω to its maximum of 10 kΩ.

Let's speak now about switch buttons, the wiring and how to implement the code for this circuit elements in Arduino. Switch buttons connect two points in a circuit when you press them and maintain the state without the need to keep the button pressed. That means that logic state of the circuit change every time you press the button.

Touch sensor (also known as touch button) is widely used to control devices. It detects touch, force or pressure on its surface changing the logic state of the circuit. Actually, it works in very similar way as to buttons. Checkout the wiring and Arduino code implementation to track the current state and the state changes.
