R4DWHTWHTHF0 application field and working principle

Rocker switches are multiple-pole, single-throw (SPST) switching devices which can switch an electrical circuit by applying a moment pressure. SPST switches are used to "weak up" a filament lamp, increase fan speed or switch between different power sources. The main application fields for rocker switches are automotive and electrical applications.

Working Principle

Rocker switches typically consist of a base, an operating lever or "rocker" and a contact block assembly. The contact block assembly consists of a set of contact springs, a stationary contact and a moving contact. When the switch is toggled, the lever rocks back and forth, causing the contact springs to form an electrical connection at the contact points.

Applications

Rocker switches can be used in a wide range of applications, from everyday household items to heavy-duty industrial machinery. In automotive applications, they are commonly used in audio equipment, climate control units, and power windows.

In electrical applications, rocker switches are most often used to control the power supply to a motor. For example, they can be used to stop a motor in the event of an emergency. Additionally, they can be used to switch between different power sources and adjust fan speeds.

Advantages and Disadvantages

Rocker switches have several advantages over other types of switches. They are relatively inexpensive, easy to operate, and highly reliable. Additionally, they are often chosen for their aesthetically pleasing design.

On the other hand, rocker switches also have their disadvantages. They are limited in terms of current handling capabilities and are not suitable for applications that require high levels of accuracy or precision. Additionally, they can be difficult to troubleshoot if something goes wrong.
