Ⅰ.Common G10B Micro switch Fault Types

No Electrical Continuity

The circuit does not conduct when the switch is pressed.

Possible causes:

Contact wear or damage

Poor terminal connection

Internal structural failure

Poor Contact (Intermittent Operation)

The signal becomes unstable, switching between ON and OFF.

Possible causes:

Contact oxidation or contamination

Moisture affecting conductivity

Insufficient contact pressure

Failure to Reset

The switch does not return to its original position after being pressed.

Possible causes:

Spring fatigue

Mechanical blockage

Installation stress or deformation

Abnormal Actuation

Unstable or inconsistent tactile feedback during operation.

Possible causes:

Wear of internal metal spring structure

Long-term mechanical fatigue

Assembly deviation

Ⅱ.Micro switch Troubleshooting Methods

Basic Inspection Steps

Disconnect power supply for safety

Check for visible damage or deformation

Verify wiring connections are secure

Perform electrical continuity testing

Multimeter Testing Method

A multimeter is commonly used to check Micro switch performance:

Set the multimeter to continuity or resistance mode

Connect probes to switch terminals

Manually press the switch and observe readings

Evaluation criteria:

Normal: Conducts when pressed, open when released

Abnormal: No change or unstable signal

Ⅲ.Fault Diagnosis and Solutions

Ⅳ.Troubleshooting Recommendations

Cleaning Method

Suitable for minor contact issues:

Use electronic contact cleaner

Avoid corrosive liquids or water

Ensure complete drying before reuse

Replacement Criteria

Direct replacement is recommended when:

Internal structure is damaged beyond repair

Instability remains after cleaning

Mechanical action is clearly abnormal

Usage Precautions

To reduce failure rates:

Do not exceed rated electrical load

Avoid frequent overload operation

Prevent long-term exposure to humidity or contamination

Avoid excessive mechanical stress during installation

Ⅵ.FAQ

1. Does no continuity always mean the Micro switch is faulty?

Not necessarily. It may also be caused by wiring issues or external circuit problems. Testing is required for confirmation.

2. Can poor contact be repaired?

Minor contamination can sometimes be improved by cleaning, but structural wear usually cannot be permanently repaired.

3. How can I quickly check if a Micro switch is working?

Use a multimeter to test continuity changes during actuation. This is the most direct method.

4. How should Micro switch faults be handled?

First check wiring and appearance, then perform electrical testing, and finally decide whether cleaning or replacement is needed based on results.
