Snap action, limit switches are electromechanical devices that act as automatic on/off switches that are used to control the flow of electricity in a circuit. They are called limit switches because they are used to limit the amount of current in a circuit or system. These switches are commonly used in industrial and commercial applications, such as controlling a processing machine or monitoring an HVAC system. The YA-2R-A2 is a popular type of snap action, limit switch.

YA-2R-A2 Application Field and Working principle

The YA-2R-A2 is a type of snap action, limit switch that is most commonly used in industrial and commercial applications. It is typically used to control the flow of electricity in a circuit or system, and it is designed to prevent too much current from flowing through the circuit. This type of limit switch is made up of two parts: an actuator and a contact. The actuator is a plunger that is connected to an internally mounted spring. When an object is placed in the contact region of the actuator, the plunger is pushed down against the spring and the contact is actuated. This causes the switch to turn “on” and allows an electric current to flow through the circuit.

The YA-2R-A2 can also be used to control the flow of air in an HVAC system. In this application, the limit switch acts as an air flow monitoring device that monitors the air flow in the system and turns “off” when the airflow exceeds the pre-set limit. This helps to ensure that the system operates at optimal levels and prevents excess air from entering the system, which can over-pressurize the system and reduce energy efficiency.

The YA-2R-A2 snap action, limit switch is an inexpensive and reliable way to control the flow of electricity or air in a circuit or system. It is designed to be easy to install and maintain, and it is available in a variety of sizes and configurations. This makes it a great option for a wide range of industrial and commercial applications.
