On a non-tactile switch, the bottom side of the overlay is connected to a conductive pad, or an upper circuit layer is printed with conductive traces. When the overlay is pressed down the conductive traces connect to the lower circuit layer which sends a signal to a printed circuit board. For the Rigid circuit membrane switches, the circuit is rigid printed circuit board. The reason why the China membrane switch panel is widely used is because of some very superior performances. It can fulfill various requirements of users, from industrial equipment to medical equipment. “Customer first, quality first, create value together.” We continue to pursue technological progress, the win-win between clients and us.
Internally, the switching mechanisms are via metal domes or conductive shorting pads. Further enhancements include surface mount LEDs, water clear widows, dead fronts, back-lighting with optic fibre orelectroluminescenceand solid mounting plates. Terminations to the PCB can be via Berg connectors and Nicomatic connectors or designed to fit Ziff connectors.
A custom membrane keypad, or custom membrane keyboard, is a very versatile electronic component. When engineered correctly, membrane switches are a hard wearing and reliable form of switch technology used extensively across a wide range of electronic applications and industries. Proven and compact, our membrane keypads are manufactured from MacDermid Autotype polyester film and can incorporate embedded smd components and back lighting technologies. Membrane switches have always been the technology of choice for heavy-duty environments that require a high level of robustness. Membrane keypads can be made perfectly dust and watertight and resistant to chemicals and other forms of pollution, which make them ideally suited for outdoor and industrial environments.
With membrane keypads, functionality is critical – they must meet your specs, and they must function accurately. From simple switches to complex membrane keypad architecture for instrumentation panels and industrial keypads, NFI Corp has the experience and expertise to bring your project to life. Tactile devices can easily be incorporated into the membrane switch to provide feedback to the operator that the switch has been activated.
The upsides of Membrane consoles are aesthetic look, toughness, naturally protected and financially competitive. A Membrane Keypad switch is a straightforward electrical gadget used to coordinate the stream of low voltage, low current power through an electrical circuit. The low current levels required by film switches make them especially helpful in incorporated circuit applications. Film Keypad switches are of two sorts relying on the way of their development. Our experienced engineers help identify the right user interface technology, and integrate the components into one fully-tested interface assembly package. The rich’s specific experience and competence lie in the manufacture of screen printing, die-set and assembly technology.
