Test content

1) Mechanical lifespan testing

-Single point lifespan: 500000 to 1 million presses

-Multi point linkage: Simulate real program cycles (such as "power → start → pause → dehydration"), continuously 500000 times.

-Texture detection: Consistent feedback every time pressed, without any jamming, collapse, weak rebound, or looseness.

-Appearance inspection: No cracks, paint peeling, wear or exposed substrate after 500000 cycles

2) Electrical performance testing

-Reliability of conductivity: 100% triggering per press, without poor contact, signal loss, or false triggering.

-Contact resistance: ≤ 50m Ω (within 1.5 times the initial value), without arc erosion or contact oxidation.

-Function linkage: After pressing the button, the entire machine program will execute normally

-Current monitoring: The working current is stable, with no abnormal fluctuations or short circuits.

3) Environmental durability testing

-High temperature lifespan: 500000 consecutive presses at 40 ℃ environment.

-Damp heat lifespan: 300000 consecutive presses at 40 ℃ and 85% RH

-Cold temperature cycle: -10 ℃ → 23 ℃ → 40 ℃ cycle, each 100000 times, without failure.
