Rocker Switches are special types of switches that are used to control electrical components or machines. The FRN91-13BB is a rocker switch that is capable of a wide range of electrical operations. It is a self-illuminating rocker switch that features both a momentary and maintained contact, thus making it suitable for a variety of applications. In this article, we will look at the application field and working principle of the FRN91-13BB.

Application Field

The FRN91-13BB is primarily used in industrial applications where momentary on and off switching are required. It is often used to control machinery and electrical components, such as contactors, starters, relays, etc. This rocker switch is designed for both indoor and outdoor applications, so it can be used for a variety of projects. In addition, this switch can also be used for applications such as illumination, voltage measurement, and temperature control.

Working Principle

The FRN91-13BB is a single-pole, double-throw (SPDT) rocker switch. This means that when the switch is actuated, one circuit is disconnected while the other circuit is connected. When the switch is not actuated, both circuits remain open. The "throw" of a switch refers to the distance between the contacts, and in the case of the FRN91-13BB, it is 2.1mm. The contact material is silver, which provides excellent electrical contact and long-term durability.

The FRN91-13BB is also self-illuminating, which means that it has an LED light that is triggered when the switch is activated. This LED can be used as a warning or indication light, or just for aesthetic purposes. The LED is rated for up to 1W and is available in either blue or red colors.

Finally, the FRN91-13BB also has a slow-make feature. This feature is designed to prevent switch bounce and reduce electrical noise when the contacts make or break. It works by delaying the energization of the contacts until the switch has been pressed for a set amount of time. This feature makes the switch more reliable and increases its durability.

Conclusion

The FRN91-13BB is a rocker switch that is used in a variety of industrial applications. It has both momentary and maintained contact operations, which makes it suitable for controlling machinery and electrical components. The self-illuminating LED and slow-make feature make it an ideal switch for a wide range of projects. With its robust design and reliable performance, the FRN91-13BB is sure to provide years of reliable service.
