It is available in a wide variety of configurations and can be adapted to suit any kind of requirement. This article will discuss the application field and working principle of the 520.02-BLK Pushbutton Switch. Application FieldsThe 520.02-BLK Pushbutton Switch is suitable for use in a variety of fields. It can be used in a variety of industrial applications such as medical, food processing, automotive, and industrial manufacturing. It can also be used in recreational applications, including gaming and entertainment. It is suitable for use in light commercial applications such as office spaces, retail stores, and educational institutions. The switching performance of the 520.02-BLK Pushbutton Switch makes it extremely useful for applications requiring constant on/off operation, such as switches for elevators and commercial doors. Working PrincipleThe 520.02-BLK Pushbutton Switch consists of two separate components: a plunger and a spring. When the plunger is pushed, it compresses the spring, which then pushes back against the plunger. This creates a momentary electrical contact that causes the switch to "close", activating the circuit. The switch returns to the "open" position when the plunger is released, thus deactivating the circuit. In addition to working as a momentary switch, the 520.02-BLK Pushbutton Switch is also capable of being wired to provide "latching" action. This means that the switch stays in either the "open" or "closed" position until the plunger is pressed again. Features and SpecificationsThe 520.02-BLK Pushbutton Switch has a variety of features and specifications that make it suitable for many applications. The switch itself is rated for up to 20,000 operations per hour. It contains an internal load limit of 30VA at 20A and a UL rating of VDE 0201. The switch is available in 1NO, 1NO+1NC, and 2NO+2NC versions. The plunger is constructed of nickel-plated brass, while the housing is made of polyamide 66 with a metalized contact. It has a mechanical life of 400,000 operations and an electrical life of 100,000 operations. ConclusionOverall, the 520.02-BLK Pushbutton Switch is a versatile and reliable switch that is suitable for a number of applications. It is easy to install and use and has a long lifetime. Its simple working principle and reliable performance make it one of the most popular switches on the market today.
