Pushbutton Switches

Pushbutton switches are manual devices with a button-like actuator that controls one or more circuit functions. This type of switch comes in a variety of electrical configurations and ratings for a wide array of applications. Among these varieties is the ABD202N-B, a two-pole, one-throw pushbutton switch. Designed for use in medium- to high-power electrical circuits, its applications and operating principles are discussed in detail below.

ABD202N-B Application Field

Much like its counterparts, the ABD202N-B is designed for use in a wide array of indoor and outdoor electrical circuits. Specifically suited for higher-power applications, its contact rating is up to 16A at 250VAC, 8A at 30VDC, 1HP at 277VAC. As such, the ABD202N‒B is usually employed in industrial or commercial settings, including industrial machinery, office equipment, automated warehouse systems, and computer-driven systems. The ABD202N-B is also designed for use illuminated pushbuttons for convenient on/off applications.

Working Principle

The ABD202N-B\'s working principle is straightforward and simple. The switch is essentially comprised of one or more actuating mechanisms, commonly referred to as contacts, which are opened or closed when the actuator button is depressed or released. When the switch is open, the contacts are separated, interrupting the current flow between them. However, when the switch is closed, the contacts are connected, allowing for the current to flow freely. In the ABD202N-B, the two poles act independently of one another, meaning each contact can be operated independently.

The ABD202N-B\'s actuating mechanism is designed to withstand higher-power circuits, and it is rated up to 1000 operations per minute or 30 cycles per second. In order to support the higher electrical requirements, the ABD202N-B is uniquely constructed using silver-nickel alloy contacts and a zinc die-cast housing with a high-temperature resistant plastic actuator.

The ABD202N-B also features a double-break design, which ensures reliable switching by electrically separating the poles when the switch is in the open position. This ensures safe and reliable operation, even when the power level is high. In addition, the ABD202N-B has a secure and solid actuating feel, allowing operators to easily locate and operate the switch in dark or cramped environments.

Conclusion

The ABD202N-B two-pole, one-throw pushbutton switch is designed for electrical applications that require higher-power circuits. It’s designed accordingly, with a double-break design, silver-nickel alloy contacts, and rugged zinc die-cast housing for reliable and safe operation at power levels up to 16A at 250VAC. Ultimately, the ABD202N-B is an ideal choice for applications that demand reliable and secure operations, such as industrial machinery, office equipment, automated warehouse systems, and computer-driven systems.
