Snap Action, Limit Switches: AZ47019 Application Field and Working Principle

Snap action, limit switches are a type of mechanical device used to control various thermal and electrical processes. Developed by the German manufacturer AZ47019, the switch is known for its rugged design, reliable operation, and economical cost. This article will provide an overview of the AZ47019 switch\'s application field and working principle.

Application Field

AZ47019 limit switches are among the most widely used in the industry. The switch\'s robust design makes it suitable for applications in harsh industrial environments, while its economic cost appeals to both large and small operations. The switch is designed to be used in a wide variety of thermal and electrical applications, ranging from controlling process temperatures to monitoring supply levels in hazardous areas. It can also be used in a variety of consumer applications, such as controlling lighting, heating, and ventilation in homes and businesses.

Working Principle

The working principle of the AZ47019 snap action, limit switch is based on two distinct components: the actuator and the switch contacts. The actuator is a mechanical device, such as a lever or cam, that is attached to a small switch body. When the actuator is activated by an external force, such as a press of a button, it causes the switch contacts to move and make or break the circuit. The amount of force required to activate the actuator is adjustable, allowing the user to customize the switch to meet different types of applications.

When the switch contacts break the circuit, it triggers a series of other events, depending on the application. For example, in a process control application, the switch contacts may trigger a motor to start or stop a conveyor belt. In a consumer application, the switch contacts may trigger a warning light or sound to indicate when a process or machine has malfunctioned.

The AZ47019 limit switch is available in a variety of sizes and designs to accommodate different application needs. The switch contacts can also be made of different materials, such as silver or gold, to better withstand environmental conditions. Additionally, the switch can be purchased with mounting brackets, allowing for easy installation and integration with other components in the system.

Conclusion

The AZ47019 snap action, limit switch is a reliable and economical solution for a wide range of thermal and electrical applications. The switch’s robust design and adjustable activation force make it suitable for use in both industrial and consumer applications. The switch is also designed to be easily integrated with other components in the system, making it a versatile and cost-effective solution.
