Rotary switches are switches that are operated by rotating a spindle. Single pole rotary switches offer the advantage of switching between two contact positions with a single turn of the spindle. These switches have seen increased popularity in consumer electronics due to their low cost and reliable functioning. 09MS45-02-4-02N is one such single pole rotary switch, which has distinctive features and properties that make it suitable for a wide range of applications.

09MS45-02-4-02N rotary switches come with a UL94V0 rated plastic housing and have a maximum insulation voltage of 250V. The contact material is silver alloy, while the normally-open contact is silver palladium. This rotary switch is designed to operate between -40°C and 85°C, with a storage temperature ranging from -40°C to 120°C. This switch is intended for dry locations and comes with an IP rating of IP 68, ensuring excellent dust resistance. Its dielectric strength is 500V RMS.

09MS45-02-4-02N has a rotational life of 20Kcy and a contact life of 10Kcy. It has a power rating of 10W at 25°C ambient temperature and a maximum contact resistance of 40mΩ. The life of this switch is long, as it can tolerate extreme temperatures and humid conditions.

The particular application fields of 09MS45-02-4-02N rotary switches are consumer electronics, automotive, audio, video and industrial use. This switch can be used in applications such as AC/DC power switching, lighting controls, low voltage switching, and fan speed control. It can also be used in light-duty applications, where the desired effect is to switch between two distinct electrical contact positions.

The working principle of this rotary switch is simple. At its most basic, the device is comprised of a spindle attached to an external knob which rotates a set of contacts. When the contacts are in a certain position, the switch is said to be ‘on’. When the contacts move to another position, the switch is said to be ‘off’. As it rotates, the contacts are pushed in a certain direction and the electrical circuit is disrupted or completed. The contacts of this switch can be moved by hand or by motor, depending upon the application.

The 09MS45-02-4-02N is an ideal solution for several industrial, automotive, and consumer applications. It offers reliable service, long life and comes in a robust package that ensures excellent dust resistance. Additionally, it offers a low contact resistance and low power consumption.
