Switches play a necessary role in the world of electronics, serving as the interface between circuits and control systems. Understanding the various types of switches and their applications is essential for both hobbyists and developers in the field. In this article we will talk about different types of switches available and their applications.

What is a Switch?

• A switch is a device made to interrupt the flow of current within a circuit, signifying its ability to either establish or break an electrical circuit. In essence, it serves as the mechanism for the ON and OFF operations of a device.

• Switches form an integral component of the control system, without which achieving control operations is unattainable. Its primary functions encompass two modes: fully ON, achieved by closing its contacts, or fully OFF, accomplished by opening its contacts.

When the switch contacts are closed, it establishes a closed path for current flow, enabling the load to draw power from the source. Conversely, when the contacts are open, the load closes the power consumption, as illustrated in the figure below.

• Another crucial role played by a switch is the redirection of electric current within a circuit. For instance, in the depicted circuit, positioning the switch at A illuminates lamp 1, whereas positioning it at B activates lamp 2.

Are you looking to purchase an electric stepper motor to use as a component in other electronics because of its rotational mechanism? You might also be aware that not every electronic would function by following a rotational motion. Besides, they will eliminate the chances of an electric motor succeeding.

That is why the Nema 17 stepper motor was launched into the market. It can be used in any electronic device, even the ones that don't follow rotational motion to produce electricity. However, most people still need help understanding the stepper motor working principle, which is significant in convincing them about the product's benefits. 

But before we indulge in a detailed discussion about NEMA 17 stepper motors, let us first understand the product by going through its basics. 

What is NEMA 17 Stepper Motor?

It has a 1.8-degree step angle, equal to 200 steps per revolution. While the stepper motor is in function, every phase of it can crave 12 A of current at the rate of 12 V. Due to such operation; the stepper motor can hold 3.2 kg cm torque at the very least. Moreover, it has 6 color-coded wires featuring a bare lead in every one of them. 

Working Principle of Stepper Motor

The stepper motor works behind the principle of a DC motor, ensuring the motor's whole rotation is divided into equal steps. You can easily judge the stepper motor's position without any position sensor's help. It is designed to hold in a unique phase until and unless it calculates the application's speed and torque.

Now, it would do so only if terminals are applied with DC voltage when it comes to the movement. Whenever some pulse is inputted into the stepper motor, it could result in spinning and, thereby, production of the energy required for the machine to function. The stepper motors also consist of electromagnets that continuously revolve around the motor’s central iron rotor.

The primary purpose of the electromagnet is to power motor shaft rotation electromagnetically along with gear teeth. The electromagnets can also be turned off at will, resulting in the next one starting to rotate the motor. It is the working principle of the stepper motor, which goes through an entire rotation while completing the exact steps for generating the torque for the inputted machine.
