Tactile Membrane Switches

Membrane switches are part of a range of tactile switch devices, and are considered to be “user interfaces” or “Human Machine Interfaces” (HMIs). Membrane switches and keypads come in many configurations, and are generally used to control various kinds of circuits.

Membrane switch circuitry can be screen-printed using conductive inks (most often carbon or silver conductive ink), and membrane switch technologies offer complete customization.

Whatever your preference is for membrane switch technology, all emerge from a simple design that consists of a circuit layer, a circuit spacer layer, and pressure sensitive adhesives housed between a strong base and a protective, functional top interface layer.

When working with our e₂ip experts, we will recommend the most suitable customization options for your specific application, choosing from a wide range of membrane switch possibilities. This can mean the incorporation of other innovative technologies, or implied visual or tactile designs.

Much of the time, the customizations chosen for projects will involve the outer interface layer and different switch mechanisms.

Membrane switches and keypads are found everywhere, and are well known for offering an incredibly smooth user interface and experience. This comes from a combination of intuitive surface layout design and optimization of individual keys or buttons for sharp tactile feedback.

It is this response sensation, or tactile feedback, that distinguishes these types of membrane switches from their alternative, non-tactile switches.

A membrane switch can also be designed to visually disappear into their housings (referred to as a dead-front effect) for additional visual appeal and seamless surface integration – all while still offering clear and accessible functionality to the user.

Like many of the technologies e₂ip offers across its commercial repertoire, membrane switches and silicone keypads characteristically contain few components by design. This means added durability, portability, and ease of integration into many applications. It also means these types of units can be easy to clean, simple to maintain, and particularly suitable where sanitation is a critical factor.
