Rocker switches are commonly used to control the flow of power in a variety of point-of-use applications. The most notably recognizable feature of rocker switches is the two-position or two-polarity switch that can easily be operated with an upward transition for one polarity and a downward transition for another. The H8503VBBR2-B series of rocker switches from Vishay provides valuable solutions to engineers and designers seeking better control solutions. The primary features, application fields and operating principles of this high-performance series are discussed in this article.

The H8503VBBR2-B rocker switches are compact devices that offer two positions with independent control of two circuits. They provide a high level of control with fast response times and are available in two operating temperature ranges: -20°C to +85°C and -40°C to +105°C. The switches typically feature a maximum carry current of 5A and maximum switching power of 500W. They also offer high insulation of 4,000VAC between adjacent contacts, and IP67 protection when mated with a compatible IP67-rated guard component. The switches feature an LED illumination option for indicators and are available with multiple actuator options.

Typical applications for the H8503VBBR2-B series include automotive interior and exterior lighting, industrial control systems, consumer applications, telecommunications, and medical equipment. The switches are suitable for point-of-use applications that require a reliable switch with a high level of protection against shorting or arcing. They are also used to control the flow of power in consumer electronics, medical systems, and communications systems.

The working principle of the H8503VBBR2-B rocker switches is relatively simple. When the switch is activated, the electrical current flows through two different circuits–one with an upward polarity and one with a downward polarity. For example, when the switch is pressed down, it will turn on the downward polarity circuit and disconnect the upward polarity circuit. Similarly, when the switch is pressed up, the upward polarity circuit will be connected and the downward polarity circuit will be disconnected. This provides reliable, quick and convenient control for point-of-use applications.

In conclusion, the H8503VBBR2-B series of rocker switches are a valuable solution for point-of-use control. The primary features, application fields and operating principles have been discussed here. The switches offer a high level of control, fast response times, high insulation and excellent protection against shorting or arcing. They are also suitable for a wide range of applications including automotive, industrial, medical and consumer electronics.
