Membrane Switch Characteristics
Membrane switches are available in various forms and are capable of providing different feedback levels to the user. When you work with us, you’ll notice we use terms such as audible, tactile, snap acting dome and poly-dome when discussing the feel and behavior of your membrane switch.
Characteristics of traditional membrane switches – Traditional switches use a printed polyester membrane with a printed layer of conductive silver ink as the circuit and actuation layers. Membrane layers are separated by a spacer that provides a gap between the upper and lower circuit to keep the switch in an open state. Pressing on the switch location compresses the upper circuit and causes the printed silver contact area to bridge the gap, close the contact, and complete the circuit. When pressure is released, this restores the gap. This type of membrane switch does not provide any feedback to the user other than the event taking place.
Additional options – We can also incorporate a thermal-formed polyester switch layer at the contact locations (printed with conductive silver) that are embossed (raised) to form a dome. These poly-domes then take on some of the behavior of a snap acting metal dome to provide positive tactile feedback, but they generally do not provide audible feedback. Another option is to employ a hybrid design that incorporates a printed circuit board (PCB) as the lower circuit and any combination of membrane, dome or poly-dome employed as the upper circuit.
