Membrane switches are essentially a sandwich of thin layers that are bonded together using pressure sensitive adhesives

Depending on the application requirements, a membrane switch will consist of as few as 4, and as many as 9 layers. The ultimate purpose of a membrane switch is to serve as the interface between man and machine, enabling an operator to communicate with a piece of equipment, instrument, or machinery. Because of the relatively short travel of membrane switches, it is often necessary to provide users with some type of feedback.

This type of membrane switch uses metal dome as the upper circuit layer of the switch. By pressing the key, the metol dome central point will connect the lower circuit, then trigger with a singal. Metal dome is usually made of stainless steel, which is flexible and can be pressed more than one million times. This three-layer switch, comprised of graphic overlay, a circuit spacer, and a screen-printed silver ink circuit, is the simplest type of membrane switch.

Moisture seals can be added for the extra durability your device needs. This protective layer is submersible and able to withstand moisture and water spray. Join our Social Community and keep in touch with all our latest technology investments, current news, upcoming events, and promotions.

We currently specialise in the low to medium volume manufacture of flexible and rigid membrane switch panels. Despite their difference, tactile and non-tactile membrane switches are often successfully combined within the same membrane switch panel. The principle of a non-tactile switch is similar to that of a tactile switch, except it does not elicit a tactile response. Non-tactile switches are self-contained units with the bottom of the overlay attached to a conductive pad.

The antimicrobial protection is directly integrated into the hard-structured coating to ensure an even distribution of the antimicrobial agent across the entire overlay for the product’s service life. Hoffmann + Krippner membrane switches offer over one million operations or switching cycles, in a variety of environmental conditions. 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.

Depending on the size of the button, the material is thick, the touch force is increased, and the response is slow; the material is too thin, the feel is poor when touched, and the rebound is not obvious. Will work with you to select the best materials for your application. We manufacture high-quality membrane switches for a variety of industries, including medical, appliances, transport, and industrial.
