₨ 150.00
3X4 Flexible Matrix Keypad has 12 buttons, arranged in a 3X4 grid. It’s made of a thin, flexible membrane material The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to connect the key pad.
3X4 Flexible Matrix Keypad membrane switch is a printed electronic circuit that uses pressure to open and close a circuit.
The membrane switch circuitry is most often screen printed using conductive inks, which are typically made of silver, carbon, and/or graphite.
It’s made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything.
The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.
12 Key Membrane Switch Keypad provides a useful human interface component for microcontroller projects.
Membrane switches are part of a range of devices considered to be user interfaces (also called operator interfaces, or man-machine interfaces) along with display-based touch screens, and mechanical switches such as push-button, toggle, rocker, and slide switches.
The ultimate purpose of a 3X4 Flexible Matrix Keypad is to serve as the interface between man and machine, enabling an operator to communicate with a piece of equipment, instrument, or machinery.
12 key Membrane Switch Keypad is high-quality soft touch feeling button keypad with 100 million life-stroke lifespans and good resistance to environmental conditions.
This is a membrane keypad with no moving parts. A female 7-pin berg connector is require for interfacing it with your microcontroller circuits.
