Rotary switches are frequently used in applications that require multiple connections and physical separation between the inputs and outputs. The 09A90-03-1-04N is a type of rotary switch, also referred to as a rotary selector switch, that has a 9-pole 10-position rotary switch. It is intended for manual control applications requiring high contact reliability.

The 09A90-03-1-04N has an external mounting side which has a detent on the rotor, so that it can move precisely from one position to the next, and has a secure position when moving to a new setting. This provides the user with an intuitive way to switch between settings. An open contact will automatically disengage when the switch is moved away from it.

The 09A90-03-1-04N rotary switch is used in applications such as controlling motor speed, selecting between different systems or signals, and changing the direction of a signal. The switching mechanism across the 9 poles and 10 positions allows for various combinations of straight-through, on/off, and center-off connections. It is suitable for use in environments which experience high shock and vibration.

The 09A90-03-1-04N works on a simple principle. Electrical power enters into one of the terminals. This energizes the switch and completes the circuit to the other terminal. As the switch is turned, different terminals and contacts make and break connection, thus allowing the user to select different settings. The static contact pressure ensures that a strong connection is always made, whereas the wipe contact ensures that no dust or other impurities interfere with the electrical connection.

The 09A90-03-1-04N rotary switch is specifically designed for applications that require a reliable manual control with snap action. Its pole count and positions make it suitable for any application needing multiple inputs, outputs, and combinations thereof. Its rugged construction ensures that it is reliable even under harsh conditions, making it a great choice for many applications.
