Brief Description of membrane switch
A membrane switch is an electrical control for turning a circuit on and off.
Membrane switches are more cost-effective and take up less design space than mechanical switches or buttons because of their low profile.
Membrane switches are easy to clean which makes them ideal for Medical or industrial controls.
You may have held a dozen membrane switches and not even known it.
A slim-profile plastic remote controller, keypad, or touchpad with buttons consisting of raised impressions in a sealed outer layer is almost certainly a membrane switch.
The advantages of membrane switches
Membrane switch keypads are convenient, inexpensive, and highly portable.
Membrane switch (also known as a touch switch or membrane keypad) is constructed from flexible layers or ''membranes'' thin like plastic wrap but made of polyester – sandwiched together like stacked sheets of paper. These layers can interact with each other when stimulated from the top down of membrane switch.
The flexible, pressure-sensitive membranes have a circuit printed on them with conductive ink. Common materials for this ink include copper, silver, or graphite.
The circuit of membrane switch can be actuated by pressure from the upper layer, printed with a graphic to indicate where to touch.
The interacting layers are sealed together with adhesive to create a self-contained, low-voltage circuit in a tiny package.
Features of membrane switches
Membrane switches are considered ''momentary action”switches.
Simply, this means that these circuits are always ''open''.
By pressing a button on the outer layer, the printed circuitry is then momentarily ''closed”until the pressure is released.
This closing triggers the action or function of the membrane switch.
Comparing this to a mechanical switch, the same function can usually be achieved with a traditional toggle switch but constructed from bulky metal or plastic parts.
Numerous functions of a touchscreen can be fulfilled by a membrane switch, but with far less circuitry and voltage requirements.
For many applications, membrane switches are the ideal solution.
