A rotary switch is an electrical switch that is activated by rotating the switch barrel through a predetermined arc to a certain position. The 09A30-05-3-02N model is a surface-mount type of rotary switch that is distinguished by its small body size of 0.6 x 0.6 inches (15.24 x 15.24 mm). It is also designed with a standard host of 500 operations and a lifecycle of 10,000 cycles. Its contact materials consist of silver with gold plating.

This model is commonly used in low voltage DC (direct current) applications, and is best suited for on/off applications due to its single pole-double throw (SPDT) configuration. In single pole-double throw configurations, a single input switch provides two outputs (one being “off”, the other being “on”). The 09A30-05-3-02N has a switching of 0.4VA (max) and a 30-degree mechanical indexing that is adjustable from 30 to 330 degrees. Other traditional applications of rotary switches are volume control, lighting control, and multiplexing.

Principle of Operation

The 09A30-05-3-02N rotary switch operates on a simple principle. A cam mounted on the switch shaft turns a stationary contact block. The motion of the cam opens and closes the contacts connected to the contact block in various positions of the switch. This is known as a mechanical connection and is used in applications that require the switch to remain stable in one position. As the cam rotates, it forces the contacts connected to the switch body internally to open or close in order to make or break the circuit. The contact that is closed will remain so until the switch is moved to another position, at which point the contacts that were closed will open and the contacts that were open will close.

Application Field

The 09A30-05-3-02N rotary switch can be used in a variety of applications. For example, it can be used to control electrical systems such as lighting systems, heating/ventilation and other similar home appliance control systems. It can also be used as a switching device to perform multiplexing by connecting multiple contacts and switches. Additionally, because of its small body size, it can be used in computer applications, such as controlling the power supply to various components. Additionally, it can be used in security systems or to control access to certain areas.

In automotive applications, the 09A30-05-3-02N can be used for vehicle control, speed control, and brake control. Additionally, it can be used to control ventilation and fans, as well as for diagnosis and operation control. It can also be used in audio/visual systems, such as for switching between sound channels.

The 09A30-05-3-02N rotary switch is a reliable and durable switch that is suitable for many applications. It is a versatile and cost-effective solution for a variety of applications and is an ideal choice for those looking for a high-quality product with a wide range of options.
