MATRIX Ball Rolling Switch Module GPIO, 3.3/5V Small 2.54 mm pitch pin-header PCB Dimension(mm): 16x 16 The Matrix-Ball_Rolling_Switch module is a ball switch. It is easy to use. You can just con-nect it to a master device with dupont cables. It works with all FriendlyARM boards, Raspberry Pi boards and Arduino boards. Its electrical characteristics are very similar to a mercury switch's however a mercury switch is easily broken, oxidized, leaking and not environment-friendly. This ball switch prevents all these issues.The switch is free to move any angle and if that angle is between 15 degrees and 45 degrees a signal will be generated and used as an input to a Schmitt trigger.
