Capacitive touch membrane switch offers great design flexibility, durability, and a sleek appearance. The technology in this style membrane switches use conductive ink printed circuitry to create an electrical circuit layer. When a human finger touches the key, an increase in the capacitance is recognized by the IC, which activates the output of the key.

Mechanical Structure of a Capacitive Touch Membrane Switch

Capacitive Touch Membrane Switch Structure

More Durable Than Traditional Membrane Switches

One of the main advantages of capacitive touch membrane switches is that there are no any mechanical components that repeat thousands of actuation cycles like metal domes in traditional membrane switches. This key advantage significantly extends the life of the product and makes it much more durable than traditional membrane switches. The overlay material can be glass, acrylic, polyester, or polycarbonate. but it should be transparent or translucent, since it needs the light pass through. The smooth top surface allows for quick wipe downs and is able to withstand harsh chemicals. These advantages make this solution extremely appealing for medical applications. We utilize our proven design techniques to completely seal the perimeter of the membrane switch from moisture, dust, and other environmental contaiminants.

Improved Esthetics

Capacitive touch membranes are an excellent solution for customers who are looking to redesign their existing, outdated product. With a sleek, glossy interface and uniform backlighting options, capacitive touch membranes can provide your existing product a major esthetic and functional improvement.
