How does electricity flow in a circuit?
To understand this question, you must be knowing that how electricity flows in a circuit. For instance, I build a small circuit with a 1.5 volt battery and one 3 ohm resistor. Then the electricity flows in the circuit only if there is a difference between the potentials of its terminals. You must have studied that usually water (and some other substances) flow from a place of higher concentration to a place of lower concentration. This is the same case with electrons, i.e., they flow from a place where potential is greater to a place where potential is lesser.
How to tell if a switch is analog?
One test to determine if a switch is analog is to actuate it without power and then apply power to see if it worked. An (analog) correction, digital switch will not operate without power. An AM or FM switch on a digital car radio is an example. Try switching bands with the radio off to see how this works.
What is the difference between a digital switch and a radio?
Digital switches are more expensive and complex in their electrical operation. Some digital radios use an analog “switch” for the volume control. The control just goes around and around and it is the rotation and not the position that changes the volume. The advantage is a much finer volume change with rotation.

What is the switch on a radio?
Some digital radios use an analog “switch” for the volume control. The control just goes around and around and it is the rotation and not the position that changes the volume.

What happens if a circuit is not supplying power?

There are basically two types of switches, Analog or digital. An analog switch physically makes a hard wired connection when on. A digital switch operates with a “pulse” type action that uses an electronic switch.
Is power used in electrical circuits?
The answer to your question requires a tiny bit of electrical knowledge. In any electrical circuit, power is only used where there is a complete path for current flow. The switch in your circuit description powers nothing, such as no lamp in the fixture, this no pathe for current to flow. Thus no power is used.
Can you switch bands without power?
