Rotary switches are an important part of the electrical and electronic systems. As the name implies, this switching device is used to control and distribute power. The 09S90-02-2-02N is a rotary switch that is typically used in industrial applications. Here, we discuss its application field and working principle.

The 09S90-02-2-02N rotary switch is primarily used in high voltage and current applications. These switches are resistant to short circuit and overload. The 09S90-02-2-02N has contacts that are rated for high-voltage applications up to 2500V and high-current applications up to 1000 Amps. It also features a high-temperature rating, ensuring that the switch operates up to 140 °C without degradation or damage.

Since the 09S90-02-2-02N rotary switch is designed for use in industrial applications, it conforms to the relevant IEC standards and has additional certifications such as the UL, IEC and CSA. The 09S90-02-2-02N is a UL-approved device that is UL and CSA listed.

Now let\'s look at the working principle of the 09S90-02-2-02N rotary switch. Rotary switches are mechanical devices that rely on the contact resistance between external control elements, such as a cam and a set of contacts. In a rotary switch, an arm or cam is attached to an external control element in order to actuate the switch. When the external control element is actuated, the switch\'s arm rotates, whereby it makes or breaks contact with the set of contacts.

In the case of the 09S90-02-2-02N rotary switch, a simplified version of the above mechanism is employed. It features an external crank arm that rotates in order to change the position of the switch contacts. The crank arm is connected to a shaft which is driven by an external actuator, such as a motor.

The position of the switch contacts is indicated on the switch enclosure, making it easy to identify the current state of the switch. When the actuator is actuated, it rotates the crank arm which in turn rotates the shaft and changes the position of the switch contacts.

In conclusion, the 09S90-02-2-02N is a rotary switch typically used in industrial applications due to its robust build and high power ratings. It relies on a simple mechanical mechanism to activate the switch contacts, a mechanism which is driven by an external actuator.
