How to Use Selector 2x5 Positions Stereo: Examples, Pinouts, and Specs

The Selector 2x5 Positions Stereo, manufactured by Audiophonics, is a rotary switch designed for stereo audio circuits. It allows users to select one of 10 different input or output channels, making it ideal for applications where multiple audio sources or destinations need to be managed. This component is commonly used in audio amplifiers, preamplifiers, and audio distribution systems to provide seamless switching between audio signals.

• Audio amplifiers and preamplifiers
• Home theater systems
• Audio mixing consoles
• Multi-source audio distribution
• DIY audio projects

The Selector 2x5 Positions Stereo is a high-quality rotary switch with the following technical specifications:

The Selector 2x5 Positions Stereo has a total of 12 pins, as described in the table below:

1. Mounting the Selector: Secure the Selector 2x5 Positions Stereo to your panel or enclosure using the provided mounting hardware. Ensure the shaft is accessible for easy rotation.
2. Wiring the Selector:
   • Connect the common pin for the left channel (Pin 6) to the left channel of your audio circuit.
   • Connect the common pin for the right channel (Pin 12) to the right channel of your audio circuit.
   • Wire the input/output pins (Pins 1-5 for the left channel and Pins 7-11 for the right channel) to the respective audio sources or destinations.
3. Testing the Selector:
   • Rotate the switch to each position and verify that the correct audio source or destination is selected.
   • Ensure there is no signal crosstalk or distortion.

• Signal Integrity: Use shielded cables for audio connections to minimize noise and interference.
• Contact Resistance: Periodically clean the contacts to maintain low resistance and ensure reliable operation.
• Voltage and Current Ratings: Do not exceed the specified voltage (125V AC) and current (0.3A) ratings to avoid damaging the switch.
• Mechanical Durability: Avoid excessive force when rotating the switch to prevent wear and tear.

While the Selector 2x5 Positions Stereo is primarily used in analog audio circuits, it can also be interfaced with an Arduino UNO for digital control or monitoring. Below is an example of how to read the switch position using the Arduino:

// Example code to read the position of the Selector 2x5 Positions Stereo
// using an Arduino UNO. The switch is connected to analog pin A0.

const int selectorPin = A0; // Analog pin connected to the selector's common pin

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
}

void loop() {
  int selectorValue = analogRead(selectorPin); // Read the analog value
  int position = map(selectorValue, 0, 1023, 1, 10); 
  // Map the analog value to one of the 10 positions
  
  Serial.print("Selector Position: ");
  Serial.println(position); // Print the current position to the Serial Monitor
  
  delay(500); // Wait for 500ms before reading again
}

Note: To use the Selector 2x5 Positions Stereo with an Arduino, you may need to add resistors to create a voltage divider for each position. This ensures that each position corresponds to a unique voltage level that can be read by the Arduino's analog input.

1. No Signal Output:

   • Cause: Incorrect wiring or loose connections.
   • Solution: Double-check the wiring and ensure all connections are secure.

2. Signal Crosstalk Between Channels:

   • Cause: Poor shielding or improper grounding.
   • Solution: Use shielded cables and ensure proper grounding of the circuit.

3. Switch Feels Stiff or Difficult to Rotate:

   • Cause: Dust or debris inside the switch mechanism.
   • Solution: Clean the switch with compressed air or a contact cleaner.

4. Audio Distortion or Noise:

   • Cause: High contact resistance or poor-quality connections.
   • Solution: Clean the contacts and use high-quality connectors and cables.

Q: Can this selector be used for mono audio circuits?
A: Yes, the Selector 2x5 Positions Stereo can be used for mono audio circuits by wiring only one channel (left or right).

Q: Is the switch compatible with digital signals?
A: While the switch is designed for analog audio signals, it can handle low-frequency digital signals within its voltage and current ratings.

Q: How many cycles can the switch handle before failure?
A: The Selector 2x5 Positions Stereo is rated for thousands of switching cycles, ensuring long-term durability.

Q: Can I use this selector for video signals?
A: No, this selector is not suitable for high-frequency video signals due to its design and contact resistance.
