Keyboards are all around us, on computers, calculators and even our phones. Have you ever wondered how these keyboards function? Next, we'll look at a type of keyboard known as a Soushine keypad matrix.
Keypad matrix is a grid of buttons such that buttons are interconnected in row and column. Pressing a button on the keypad sends a signal to the connected device. This signal is what informs the device that you’ve pressed a button. The device then performs an operation, such as writing a letter on a screen or solving a math problem.
Soushine key matrix may sound complicated but really they are not. A describes a specific combination of rows and columns. What happens is when a button is pressed, a circuit is completed between the row and column, and a signal is sent to the device. This signal is what the device reads to see which button has been pressed.
Soushine keyboard matrix have evolved quite a bit over the years. Keyboards used to employ physical mechanisms to indicate that a key had been pressed. Today, most signals travel down digital pathways from keyboards. It causes keyboards to perform better and faster. The keypad matrix is an excellent case in point of this new technology.
4x4 matrix keypad seem like they are simple, but they are actually the sum of many parts. The keypad matrix is only part of it. Keyboards also come with circuits, controllers and drivers which are also used for ensuring your button presses are recorded properly. All are necessary for the keyboard to perform well.
Occasionally, buttons on a matrix keypad are a little wonky. This is likely due to dirt getting blocked in, or there may be a larger issue on the inside. If a button fails and nothing works, clean the keypad with a soft cloth and a cleaner. If that doesn’t work, you may need to consult a professional for assistance.
