Test Equipment & Setup
| Item | Parameter | Value |
|---|---|---|
| Instrument | Name | Key Life Testing Machine (按键寿命试验机) |
| Test Parameters | Number of Test Cycles | 10,000 cycles |
| Test Speed | 60 cycles / min | |
| Electrical Requirement | No open-circuit event during test; conduction confirmed after test | |
| Tactile Requirement | Good hand feel (actuation feel normal throughout) |
Test Procedure
- Pre-Test: Record ambient conditions (temperature 22 °C, humidity 55 % RH). Inspect 3 sample button switches visually for any pre-existing damage. Confirm part number 41SC1TVDM04B6000 on each sample.
- Sample Placement: Mount samples on the key life testing machine fixture as shown in the sample layout (see test pictures reference).
- Program Setup: Configure the machine controller for 10,000 total cycles at a speed of 60 actuations per minute.
- Test Execution: Run the programmed cycle sequence. Monitor for any conduction failure or open-circuit event throughout the 10,000 cycles.
- Mid-Test Monitoring: Verify electrical continuity and tactile response at intervals during the test run.
- Post-Test Electrical Check: Confirm electrical conduction is still normal after completion of all 10,000 cycles.
- Post-Test Mechanical Check: Verify the ON/OFF mechanical function operates correctly; check key rebound and structural integrity.
- Visual Inspection: Examine switch surface for any damage, deformation, or abnormality.
- Acceptance Criteria: No open-circuit / non-conduction event during testing; electrical conduction confirmed after test; good tactile feel; no surface damage; key rebound normal; structure intact.
Test Data & Results

Frequently Asked Questions
What does the key life test measure for the T600 button switch?
The test measures the endurance of the BM2527 push-button switch by repeatedly actuating it 10,000 times at 60 cycles per minute. It checks that electrical continuity is maintained throughout all cycles and that the button retains good tactile feel, rebound, and structural integrity after the full test run.
Why was the test speed set at 60 cycles per minute?
60 cycles per minute is a standard accelerated-life test rate that simulates years of real-world user actuation in a compressed timeframe. It is aggressive enough to surface mechanical wear without generating heat artifacts that could distort results.
What would cause a failure in this type of test?
A failure would be recorded if any open-circuit or non-conduction event occurred during the 10,000 cycles, if the switch failed to conduct after the test, if the key rebound became sluggish or the button stuck, or if visible physical damage appeared on the switch body.
Where can I find the full specification for the ETENWOLF T600 digital tire pressure gauge?
