09A90-03-1-02N

A rotary switch is an electrical switch with multiple positions. Its name derives from its rotating actuator which, when rotated, moves between various positions, electrically connecting or disconnecting different circuits. A common example of a rotary switch is the selector knob found on stereo systems and several other consumer electronics. The 09A90-03-1-02N rotary switch is a multi-pole, low-power switch and are mainly used in low cost applications.

Application Field of 09A90-03-1-02N

The 09A90-03-1-02N is designed for commercial product applications, where cost and complexity are concerns. Its design combines the features of the basic rotary switch mechanism with the more complex features of those used in higher-end applications. It is suitable for applications such as remote switches in helicopters, telescopes, tractors, and much more. While the 09A90-03-1-02N is not suitable for high power applications, its low power rating, combined with its low cost make it ideal for many low to mid range applications.

Working Principle

The 09A90-03-1-02N rotary switch uses contacts and wipers to generate a circuit connection when the switch is rotated. The switch has two positions for the actuator, a turning arm and a switch point. When the turning arm is in the off position, the switch point is in contact with the contacts and wipers, which disconnects the circuit. When the turning arm is activated, it changes the position of the switch point to a contact point, which forms a connection with the circuit. In this way, the 09A90-03-1-02N rotary switch can be used to control the flow of electrical current or to control the operation of a device or machine.

The 09A90-03-1-02N rotary switch is a robust, reliable and efficient switch, suited to many applications. Its basic components are very simple, making it relatively inexpensive and straightforward to use. Moreover, its low power rating and low cost make it ideal for many low to mid range applications.
