Pushbutton Switches: AOFD120NUG Application Field and Working Principle

Pushbutton switches are devices that are used to control the flow of electric current. They are usually used to turn on and off electrical appliances. One type of pushbutton switch is the AOFD120NUG. This unit is an IEC rated pushbutton switch with a single-pole double-throw (SPDT) design. This switch is available in a variety of actuator styles, including: plunger-type, push/pull-type, lever-type, and mushroom-type.

Application Field

The AOFD120NUG push-button switch is suitable for use in industrial settings and in some domestic applications. The switching of loads up to 10A is allowable and the maximum switching voltage is 250VAC or 300VDC. It is suitable for direct control of actuators, fans, pumps, motors, relays, and other electrical loads. It is suitable for use in environments with a humidity of 50-90%, and its operation temperature ranges from -25℃ to +55℃. The application of this switch can be found in control systems of equipment and machinery, urban engineering, control cabinets, boiler systems, and so on.

Working Principle

The AOFD120NUG pushbutton switches utilizes two SPDT snap acting switches. When the actuator is pressed, the mechanism is pushed down, pressing the two contacts together, changing their connections from the "open" connection to the "closed" connection. When the actuator is released, the two contacts return to their original connected positions. This allows the two switches to be used in either normally-open or normally-open configurations. The switch is constructed such that contact bouncing does not occur, allowing for clean and reliable switching.

When the switch is used, the user must take into consideration the load capacity of the device and the maximum voltage allowed on the circuit. For example, the maximum switching capability of the device is 10A of current at 250VAC (or 300VDC). If the load exceeds the specified value, the device may be damaged, leading to failure and possible injuries or fire. The user must also consider any environment-specific parameters, such as the ambient temperature, humidity, pressure, and so on to ensure the safe use of the device.

Conclusion

The AOFD120NUG pushbutton switch is a reliable and durable device suitable for a variety of industrial and domestic applications. Its SPDT design allows it to be used in either normally-open or normally-closed configurations, providing the user with flexibility when designing a system. The user must take into consideration the load capacity of the device and the maximum voltage allowed on the circuit to ensure that the device is used safely and reliably.
