Introduction to Pushbutton Switches

Pushbutton switches are commonly used in a wide variety of applications, ranging from basic on/off control of motors and circuit breakers, to controlling the signal of a mechanical interlock or the direction of a current. Generally speaking, a pushbutton switch consists of two parts: the switch itself, and a mechanism that actuates the switch when a force is applied. This mechanism could be a spring-loaded plunger, a toggle lever, or a button. Depending on the use, the pushbutton switch can be configured in a variety of different configurations, with each providing different types of functionality.

The ALFD21120DNUA Pushbutton Switch

The ALFD21120DNUA is a pushbutton switch designed specifically for high-voltage, high-current applications such as industrial equipment and large appliances. In this type of application, it is important for the switch to be able to withstand high voltages and currents without damaging the contact points. The ALFD21120DNUA is equipped with a patented dual-contact system, allowing it to safely handle up to 400 volts of AC or DC current. Additionally, the ALFD21120DNUA is UL and cUL rated for locations up to ¾ of a square inch, making it suitable for use in tight spaces and small enclosures.

ALFD21120DNUA Application Field and Working Principle

The ALFD21120DNUA is a versatile switch, capable of controlling a wide range of applications. It is commonly used as an emergency shut-off switch in industrial equipment and machinery, as well as a reset button in emergency systems and alarms. This switch can also be used to control lighting and other electrical devices, such as fans and circuit breakers. In these applications, the switch generally works by providing a pathway for current to flow through when the mechanism is actuated.

The ALFD21120DNUA is constructed with a dual-contact design, which provides both robustness and high electrical isolation. When the lever or button is actuated, the switch opens and isolates the circuit from the power source, preventing any current from flowing through it. This ensures that the electrical circuit remains safe and protected against potential overloads and short circuits. In addition, the ALFD21120DNUA also offers a dual-function option, allowing it to switch both AC and DC current.

The ALFD21120DNUA is also UL and cUL rated, ensuring that it meets the highest safety requirements. This means that the switch is protected against short circuits and other potential failures, making it ideal for use in high-risk applications. Additionally, the ALFD21120DNUA is protected against moisture and dust, ensuring that it operates reliably in even the harshest environments.

Conclusion

The ALFD21120DNUA is a reliable and versatile pushbutton switch suitable for a wide range of applications. Its dual-contact design provides robustness and high electrical isolation, allowing it to control both AC and DC current. Additionally, the switch is UL and cUL rated, making it safe and reliable in even the harshest environments. With its robust construction and versatile application options, the ALFD21120DNUA is an excellent choice for controlling high-voltage, high-current applications.
