How to Use Micro Switch Hinge Roller new: Examples, Pinouts, and Specs

The Micro Switch Hinge Roller (V-156-1C25), manufactured by JANDECCN, is a precision-engineered switch designed for reliable and accurate switching operations. It features a hinge roller actuator, making it ideal for applications requiring mechanical actuation with minimal force. This micro switch is widely used in safety devices, industrial automation systems, vending machines, and limit-switching mechanisms.

• Safety Devices: Emergency stop mechanisms and interlocks.
• Industrial Automation: Position detection and control in machinery.
• Vending Machines: Detecting door or lever positions.
• Robotics: Limit switches for robotic arms and moving parts.
• Home Appliances: Used in washing machines, microwaves, and other devices.

The V-156-1C25 micro switch has three terminals for SPDT operation:

1. Identify the Terminals: Locate the COM, NO, and NC terminals on the switch.
2. Connect the Circuit:
   • For a normally open (NO) configuration, connect the load between COM and NO.
   • For a normally closed (NC) configuration, connect the load between COM and NC.
3. Mount the Switch: Secure the switch in place using screws or a mounting bracket. Ensure the hinge roller aligns with the actuating mechanism.
4. Test the Actuation: Manually press the hinge roller to verify the switching action.

• Voltage and Current Ratings: Ensure the connected load does not exceed the rated voltage (250V AC) or current (15A).
• Mechanical Alignment: Properly align the hinge roller with the actuating mechanism to avoid excessive force or misalignment.
• Debouncing: If used in digital circuits, consider implementing debouncing to avoid false triggering.
• Environmental Conditions: Avoid exposing the switch to extreme temperatures or moisture beyond its rated limits.

The V-156-1C25 can be used as a limit switch in Arduino projects. Below is an example of how to connect and use it:

• Connect the COM terminal to the ground (GND) pin of the Arduino.
• Connect the NO terminal to a digital input pin (e.g., pin 2) on the Arduino.
• Use a pull-up resistor (10kΩ) between the digital input pin and the 5V pin of the Arduino.

// Define the pin connected to the micro switch
const int switchPin = 2;

// Variable to store the switch state
int switchState = 0;

void setup() {
  // Set the switch pin as input
  pinMode(switchPin, INPUT);
  
  // Enable the internal pull-up resistor
  digitalWrite(switchPin, HIGH);
  
  // Initialize serial communication for debugging
  Serial.begin(9600);
}

void loop() {
  // Read the state of the switch
  switchState = digitalRead(switchPin);
  
  // Print the switch state to the Serial Monitor
  if (switchState == LOW) {
    // Switch is pressed
    Serial.println("Switch Pressed");
  } else {
    // Switch is not pressed
    Serial.println("Switch Released");
  }
  
  // Add a small delay to avoid spamming the Serial Monitor
  delay(100);
}

1. Can this switch handle DC loads?

   • Yes, but ensure the DC voltage and current do not exceed the rated limits.

2. What is the purpose of the hinge roller?

   • The hinge roller allows for smoother actuation and reduces wear when used with moving parts.

3. Can this switch be used outdoors?

   • The switch is not waterproof. Use a protective enclosure if deploying it in outdoor environments.

4. How do I know if the switch is faulty?

   • Test the continuity between terminals using a multimeter. If there is no continuity when actuated, the switch may be faulty.
