What is a switch life testing machine?

The switch life testing machine is a special equipment used to test the durability and reliability of electrical components such as switches, buttons, and relays under repeated operations. By simulating frequent switching actions in actual use, the device can evaluate the product's life, performance stability and potential failure points, providing data support for product quality improvement.

1. Working principle of switch life testing machine

What is a switch life testing machine?

The switch life testing machine simulates manual operation through motor drive or pneumatic device, and repeatedly presses, rotates or toggles the switch at a set frequency and intensity. During the test, the equipment will record the number of operations, current changes, contact resistance and other parameters, and monitor the failure of the switch through sensors.

test itemsParameter rangeTypical standards
operating frequency10-60 times/minuteIEC 61058
Number of tests10,000-500,000 timesGB/T 15092
Load current0.1A-20AUL 61058

2. Core functions of switch life testing machine

1.Automated testing: Supports preset programs to complete long-term testing without manual intervention.
2.Multi-channel synchronization: Can test multiple switches at the same time to improve efficiency.
3.Real-time monitoring: Record key data such as contact resistance and arc generation.
4.Failure determination: Automatically identify faults such as stuck switch and poor contact.

Function moduleTechnical indicators
Drive systemServo motor/cylinder, accuracy ±0.1mm
Data collectionSampling rate ≥1kHz, 16bit resolution
Security protectionOvercurrent, overheating, emergency stop

3. Application fields

Switch life testing machines are widely used in:
-Home appliance industry: Test power switches, thermostats, etc.
-Automotive electronics: Verify the light switch and central control button
-industrial equipment: Evaluate control cabinet buttons and emergency stop switches
-certification body: Used for CCC, UL and other certification tests

4. Precautions when purchasing

1.Test compatibility: Confirm that the device supports the type of switch under test (rocker, inching, rotation, etc.).
2.load capacity:Select the corresponding model according to the rated current of the product.
3.data output: Check whether Excel/PDF report generation is supported.
4.After-sales service: Pay attention to the calibration cycle and spare parts supply.

5. Industry development trends

With the popularity of IoT devices, a new generation of testing machines has begun to integrate:
-Intelligent analysis: AI predicts failure modes
-remote monitoring: 4G/5G real-time data transmission
-Energy efficiency test: Add power consumption measurement module
-environment simulation: Integrated temperature and humidity test function

Through the scientific testing of switch life testing machines, companies can effectively improve product reliability and reduce after-sales maintenance costs. When selecting equipment, it is recommended to refer to the newly released JB/T 7081-2022 "Switch Operation Life Testing Machine" industry standard to ensure the authority of the test results.
