Rotary Switches

Rotary switches are electromechanical devices used to control electrical circuits by manually rotating a shaft or lever. They usually consist of three or more contact points arranged in a circle or helix. The 44UA30-02-2-04N is a type of rotary switch commonly used in a variety of applications to provide reliable switching actions with long life.

Application Field

The 44UA30-02-2-04N rotary switch is typically used in industrial, commercial, and consumer products. It is a cost-effective solution for a variety of switch applications, such as manual switching of voltage levels, controlling multiple circuit branches, selecting among several discrete output signals, controlling the speed of motors and other machinery, and operating electrical circuits for on/off functionality. This type of rotary switch is also ideal for a variety of lighting applications, such as lamps and decoration lighting systems.

Working Principle

The 44UA30-02-2-04N rotary switch consists of an insulated rotational sleeve, which turns a cam, which moves a cylindrical contactor. The cam and contactor move a contact terminal located in a groove, which can make and break contact with a number of stationary contact terminals. As the contactor rotates, it makes and breaks electrical circuits and changes the current paths of the connected circuits. The 44UA30-02-2-04N rotary switch offers a longer service life than other comparable devices, due to its robust construction and sealed design. It has a rugged die-cast aluminum body, double-sealed steel bearings, and a gold-plated, corrosion-resistant shaft. Its contact terminal minimizes noise and is reliable and resistant to vibration, shock, and dust. The 44UA30-02-2-04N is also designed with a anti-vibration contactor, which reduces arcing and extends the service life of the contact points.

Conclusion

The 44UA30-02-2-04N rotary switch is a robust and reliable device designed for a variety of switch applications. It offers a long service life, due to its die-cast aluminum body, double-sealed steel bearings, and gold-plated, corrosion-resistant shaft. It is ideal for a variety of commercial and industrial applications, such as manual switching of voltage levels, controlling multiple circuit branches, selecting among several discrete output signals, controlling the speed of motors and other machinery, and operating electrical circuits for on/off functionality.
