Membrane switches comprise multiple layers of flexible film, including circuit layers, isolation layers, and surface decorative layers, achieving touch functionality through precision printing and lamination processes. Not only can they replace traditional mechanical buttons, but they can also integrate backlighting, haptic feedback, and even flexible displays, earning them the title of ‘the unsung heroes of in-car interaction’.
Lightweight and space-saving: With a thickness of just 0.5–2mm, they enable automotive manufacturers to achieve minimalist cabin designs.
Exceptional environmental adaptability: Waterproof and dustproof to IP67 standards, maintaining stable operation under extreme temperatures (-40°C to 85°C).
Exceptional longevity: Button lifespan exceeds 1 million actuations, far surpassing the 500,000-actuation standard of mechanical buttons.
Design flexibility: Supports customised patterns, translucent effects, and seamless integration with 3D curved glass surfaces.
Membrane switches have found extensive application within the automotive sector, particularly in areas such as instrument panels, door control panels, and entertainment systems. Below are the primary applications of membrane switches in vehicles alongside their advantages:
Membrane switches are frequently employed for menu selection and function adjustment on automotive instrument panels, such as volume control and temperature regulation. Their slim design and high sensitivity make them an ideal choice for interior vehicle controls.
Membrane switches can be employed for door locking, window operation, and rear-view mirror adjustment functions. Their waterproof and dustproof properties render them suitable for use in demanding automotive environments.
Membrane switches are extensively employed in automotive entertainment systems, such as auxiliary control buttons for touchscreens. Their high reliability and extended lifespan ensure stable performance under conditions of vibration and elevated temperatures.
Membrane switches may also be utilised for functions including air conditioning control, seat adjustment, and lighting control within vehicles.
