The Retroclick is a tactile switch designed to replicate the feel and aesthetic of vintage electronic devices. It provides a satisfying "click" feedback when pressed, making it ideal for applications where user interaction and nostalgia are key. The Retroclick is commonly used in custom keyboards, retro-style gaming consoles, audio equipment, and DIY electronics projects. Its robust design and unique tactile response make it a favorite among hobbyists and professionals alike.
The Retroclick is a simple yet versatile component. Below are its key technical details:
Parameter | Value |
---|---|
Operating Voltage | 3.3V to 5V |
Maximum Current Rating | 50mA |
Contact Resistance | ≤ 100mΩ |
Insulation Resistance | ≥ 100MΩ at 500V DC |
Operating Temperature | -20°C to +70°C |
Actuation Force | 50g to 70g |
Lifespan | 1,000,000 actuations |
The Retroclick typically has two or four pins, depending on the model. Below is the pin configuration for the most common 4-pin variant:
Pin Number | Description |
---|---|
1 | Switch Terminal 1 (Input) |
2 | Switch Terminal 2 (Output) |
3 | Switch Terminal 1 (Duplicate) |
4 | Switch Terminal 2 (Duplicate) |
Note: Pins 1 and 3 are internally connected, as are pins 2 and 4. This redundancy ensures a stable connection in various mounting configurations.
Below is an example of how to use the Retroclick with an Arduino UNO to toggle an LED:
// Define pin connections
const int retroclickPin = 2; // Retroclick connected to digital pin 2
const int ledPin = 13; // LED connected to digital pin 13
// Variable to store the LED state
bool ledState = false;
// Variable to store the last button state
bool lastButtonState = LOW;
// Debounce timing variables
unsigned long lastDebounceTime = 0;
const unsigned long debounceDelay = 50; // 50ms debounce delay
void setup() {
pinMode(retroclickPin, INPUT_PULLUP); // Set Retroclick pin as input with pull-up
pinMode(ledPin, OUTPUT); // Set LED pin as output
}
void loop() {
// Read the current state of the Retroclick
bool currentButtonState = digitalRead(retroclickPin);
// Check if the button state has changed
if (currentButtonState != lastButtonState) {
lastDebounceTime = millis(); // Reset debounce timer
}
// If the debounce delay has passed and the button state is stable
if ((millis() - lastDebounceTime) > debounceDelay) {
// If the button state is HIGH (pressed)
if (currentButtonState == LOW && lastButtonState == HIGH) {
ledState = !ledState; // Toggle the LED state
digitalWrite(ledPin, ledState); // Update the LED
}
}
// Update the last button state
lastButtonState = currentButtonState;
}
Explanation of the Code:
The Retroclick does not respond when pressed:
Erratic behavior when pressing the switch:
The tactile feedback feels weak or inconsistent:
Q: Can the Retroclick handle AC signals?
A: The Retroclick is primarily designed for low-voltage DC applications. Using it with AC signals is not recommended unless the voltage and current are within the specified limits.
Q: How do I clean a Retroclick switch?
A: Use compressed air to remove dust and debris. Avoid using liquids or solvents, as they may damage the internal components.
Q: Can I use the Retroclick in outdoor applications?
A: The Retroclick is not weatherproof. For outdoor use, consider enclosing it in a weather-resistant housing.
By following this documentation, you can effectively integrate the Retroclick into your projects and troubleshoot any issues that arise.
