WHAT ARE MEMBRANE KEYPADS & KEYBOARDS?
Membrane keyboards or membrane switches are pressure design pads that have only outlines and symbols printed on a flexible flat surface. Keypads work by electrical contact between the keyboard surface and the underlying circuits when the key top areas are pressed with help of an external force. The basic principle behind the functionality of a keypad is that the contact behind the tactile key or non - tactile key closes an open loop of the circuit which ends on the flexible tail. Membrane keyboard and keypads can range from flexible keyboard, backlit keyboard, waterproof keyboard, embossed keyboard, hybrid keyboard, front facia keyboard, tactile and non - tactile keyboard and many more.
