The core operational lifespan of aircraft membrane switches exceeds 5 million press cycles, with a physical ageing lifespan of 3 to 10 years. Actual longevity requires comprehensive assessment based on usage scenarios: under standard operating procedures and with effective sealing protection, performance may approach the design upper limit. However, frequent excessive force application or compromised environmental sealing may significantly reduce service life. This longevity advantage stems from aerospace-grade material selection, lightweight structural design, and high-wear-resistance manufacturing processes, substantially outperforming standard industrial or consumer membrane switches.
1) The surface material must be high-quality, corrosion-resistant, UV-resistant imported PET material;
2) The entire membrane switch product structure must meet IP65 or NEMA-4 standards, or even higher;
3) Circuitry must utilise higher-reliability FPC or PCB traces, rather than PET traces with printed silver lines;
4) After assembly onto client equipment, all openings in the membrane switch must be sealed;
5) Conduct routine inspections; should any functional failure be detected, immediately replace with new units to prevent potential hazards.
Lightweight: With a total thickness of merely 1.2–2.5mm, it is significantly lighter than conventional aluminium panels, contributing to aircraft equipment weight reduction.
Customisable: Key layouts, graphic symbols, and specialised processes (such as raised sections or viewing windows) can be tailored to meet specific aircraft operational requirements.
