Membrane switches
A solid and proven technology
Ever since their first introduction in the 1970s, membrane switches have formed the basis for solid and reliable user interfaces for any type of environment. Known for their robustness and resistance to heavy weather conditions and pollution, they are highly recommended for outdoor applications, industrial environments and heavy-duty work. But they are still a perfect fit for medical equipment or communication devices as well, as they are easily adaptable to new technologies.
Robust and resistant
Membrane switches have always been the technology of choice for heavy-duty environments that require a high level of robustness. Keypads can be made perfectly dust and watertight and resistant to chemicals and other forms of pollution, which make them ideally suited for outdoor and industrial environments. They are also easy to clean, enabling maximum hygiene for medical and pharmaceutical applications such as hospitals and cleanrooms. This does not mean, however, that membrane switches cannot look the part – Quad Industries offers a wide range of high-quality finishing options, including soft-touch keypads or a brushed steel look.
Versatile and future-proof
Although membrane switches have been around for many years, they have proven to be very versatile and easily adaptable to new technology. Quad Industries offers a wide range of modern features, including wireless connection via printed NFC, BLE or WiFi antennas, seamless integration of capacitive touch sensing and visual feedback for users through the integration of LEDs and or electroluminescence.
