Snap action, limit switches - application field and working principle

Snap action switches, also known as limit switches, are common electrical switches used mainly in industrial applications, where they are used to monitor and control the operation of automated equipment, such as robots and other automated machinery. Generally, they consist of a single switch, but some more complex switches may consist of two or more switches, which can be combined to provide additional functionality. The most common form of snap action switch is an On/Off switch.

Application Field

Snap action switches are mostly used in industrial settings, such as manufacturing plants, where they are used to monitor and control the operation of automated machinery. They are also commonly used in amusement rides, escalators, elevators, and other automated systems, where they can be used to detect the presence of an object, and to switch operations on or off accordingly.

In addition, snap action switches can be used in a variety of applications that require a precise amount of pressure to be applied to a lever or button, such as vehicle doors, fire alarms, and pressure transducers. They are also used in diagnostic medical equipment and CT scanners, where they are used to detect changes in body temperature or pressure. In addition, they can be used in vending machines and gaming machines, where they detect the presence of coins or tokens.

Working Principle

A snap action switch is essentially an On/Off switch that relies on a mechanical system, known as a snap-action mechanism, in order to activate the switch. When the switch is triggered, the mechanism rapidly snaps from one position to another. This mechanism, which is typically made of metal, contains a spring-loaded armature that moves rapidly between two positions, one open and one closed. When the armature is in the closed position, it is said to be "closed", meaning that the electrical circuit is complete and current can flow through the switch.

In order to activate the switch, a certain amount of pressure must be applied to the lever or button, which is usually provided by a cam or other mechanical device. The pressure applied to the switch causes the armature to snap into the open position, where it remains until the pressure is removed. When the pressure is released, the armature returns to the closed position, thus completing the circuit and allowing current to flow.

Usage

Snap action switches are highly versatile and can be used in a number of different applications, where they are used to monitor or control the operation of automated machinery or equipment. They are ideal for use in industrial environments, where they can be used to control various processes and operations, or to detect the presence of objects.

In addition, snap action switches can be used in medical applications, where they can be used to detect changes in temperature or pressure, as well as in vending machines and gaming machines, where they detect the presence of coins or tokens. They are also widely used in escalators, elevators, and fire alarms.

Conclusion

Snap action switches, also known as limit switches, are common electrical switches used mainly in industrial applications, where they are used to monitor and control the operation of automated equipment. They are highly versatile and can be used in a variety of applications, such as manufacturing plants, amusement rides, medical equipment, and vending machines. The working principle of snap action switches relies on a mechanical system, known as a snap-action mechanism, which causes the switch to rapidly transition between two states.
