Snap action, limit switches are electromechanical devices that are used to form control circuits as well as to provide protection against overcurrents and overvoltages, and to supervise the operating of various mechanical and electrical systems. The working principle of these switches is based on a simple principle of magnetism and inertia.

When the current flow through an electromagnet, it creates a magnetic field, which will tend to attract the armature of the switch. This armature is made of a strong metal that will not be affected by the magnetic field, and so the armature will remain in its original position until it is moved by the force of an external object. As the force increases, the armature starts to move and as it reaches the end point of its travel, a click or snap occurs, which causes the contact points of the switch to close.

In a snap action, limit switch, the material of the armature and the current flowing through the coil are two key elements that affect the snap action of the switch. The material determines the amount of force needed to move the armature to close the switch contacts. The size of the armature is also important in determining the amount of force, since smaller armatures will require less force than larger ones. The current also affects the switch\'s snap action, since higher currents create stronger magnetic fields, which can pull the armature more quickly.

Aside from the snap action, limit switches can also be used in applications where protection against over-currents, over-voltages and over-heating is needed. It is important to note that in certain applications, the snap action may not be enough to protect the circuit from a high current or over-voltage situation. In such cases, other types of limit switches or relays might be used to provide added protection.

Apart from being used in the protection of circuits, snap action, limit switches are also used in the control of machines and equipment. For example, when a door is opened or closed, a switch can be used to activate certain mechanisms or alert the operator if something is not working properly.

In addition, snap action limit switches can be used to control various process parameters, such as temperature and pressure, in industrial applications. For example, a switch can be used to control the speed of a machine or the pressure of a process, and if the parameter gets too high, the switch will open, shutting off the machine or process and preventing damage.

Overall, snap action, limit switches are versatile and reliable electromechanical devices that are widely used in the control and protection of various electrical and mechanical systems. They offer precise control, network protection and feedback from mechanical movements, and are usually the most cost effective solution for many applications.
