Snap action, limit switches are commonly used to sense and open/close circuits, providing mechanical and electrical control of motor and actuator operations. The AH74564569-A switch is an ideal solution for a wide variety of applications because of its robust design and flexibility. This guide will explain the application field and working principle of AH74564569-A switch.

Specifications

The AH74564569-A switch is a 5-pin snap action, limit switch. It features a steel housing with a white plastic body, a 3-collector moving arm with adjustable contacts, a Nylon 66 cover, and two mounting screws. The standard sensitivity range is 15-45 grams, the rated load is 5.2A, and the maximum insulation is 600V. The switch operates from 0 to 55 degrees Celsius and has an IP 20 level of protection.

Application Field

The AH74564569-A switch is widely used in industrial, automation, and automotive applications. It can be used as an E-stop switch, a speed switch, a temperature switch, and a travel switch. This switch is especially suitable for mechanical and electrical control of motor and actuator operations in arduous industrial environments. It is especially suitable for applications with tight space requirements, and can be easily installed. The switch is also widely used in the automotive industry for various functions, including door and hood open/close, window position control, horn/light activation, transmission control, and fuel level sensing.

Working Principle

The AH74564569-A switch is a snap action, limit switch, which means that it is normally closed and open when activated. When the switch is not activated, the two contacts are held together, creating a closed circuit and no current flows through the switch. When a force is applied to the movable arm of the switch, it will move, opening the contacts and creating an open circuit. This will interrupt the current flow and cause a change in the electrical circuit state. Depending on the application and the type of circuit being used, the switch may operate as a normally open or closed contact.

The AH74564569-A switch is designed to be adjustable, and the amount of force needed to trigger the switch can be adjusted by tightening or loosening the sensitivity adjust screw. Adjustment is made in the range of 15-45 grams, and can be altered depending on the application to suit different conditions. Turning the adjust screw clockwise increases the sensitivity and turning it counterclockwise reduces the sensitivity. This ensures the switch is correctly adjusted for the application and the desired output.

Conclusion

The AH74564569-A switch is a snap action, limit switch which is suitable for use in industrial, automation, and automotive applications. It has a steel housing with a white plastic body, a 3-collector moving arm with adjustable contacts, a Nylon 66 cover, and two mounting screws. The switch normally operates as a normally closed contact, but this can be adjusted depending on the application. The sensitivity can be varied by turning the adjust screw clockwise or counterclockwise, ensuring the correct output is achieved.
