Product Description
Circuit Rating: 35V (DC), 100mA, 1W Contact resistance: 10 ~ 500 (Varies according to the lead lengths and different from those of the material used) Insulation resistance: 100M 100V Dielectric Strength: 250VRms (50 ~ 60Hz 1min) Electric shock jitter: <5ms Life span: tactile type: one million timesThe mechanical properties Operating pressure: Touch feeling: 170 ~ 397g (6 ~ 14oz) Switch travel: touch-type: 0.6 ~ 1.5mmThe environment parameters Operating temperature: -40 to +80 Storage temperature: -40 to +80 Temperature: from 40,90% to 95%, 240 hours Vibration: 20G, max. (10 200Hz, the Mil-SLD-202 M204.Condition B)How keypad works & How to scan them? The working principle is very simple. Pressing a button shorts one of row lines to one of column lines, allowing current to flow between them. A microcontroller can scan these lines for a button-pressed state. To do this, it follows steps below. 1.Microcontroller sets all column and row lines to input. 2.Then, it picks a row and sets it HIGH. 3.After that, it checks column lines one at a time. 4.If column connection stays LOW, button on the row has not been pressed. 5.If it goes HIGH, microcontroller knows which row was set HIGH, and which column was detected HIGH when checked. 6.Finally, it knows which button was pressed that corresponds to detected row & column.Package Included: 6 X 16keys 4X4 Membrane switch keypad
