These silicone elastomer keypads are just waiting for your fingers to press them. Go ahead, squish all you like! (They're durable and easy to clean, just wipe with mild soap and water) These are just like the light up rubber buttons you find on stuff like appliances and tools, but these are open source and easy to integrate into your next project.\u003c\/p\u003e\n\u003cp\u003eEach button is 10mm x 10mm square and 10mm tall. There is 5mm of grid spacing between the buttons. You can 'tile' the button pads edge-to-edge and they'll grid up correctly. You can also cut the pads down if you like, the silicone is very soft. The way they're molded, they give about 3mm of travel when pressed for a very satisfying feel. They are completely quiet, however.\u003c\/p\u003e\n\u003cp\u003eOn the bottom of each button is a conductive pad ring which can close a properly design contact underneath. \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_Trellis\" target=\"_blank\"\u003eAdafruit have an EagleCad library which has objects for the buttons and optional LEDs so you can use them in your next PCB design.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eEach button is 10mm tall and can fit a 3mm LED inside quite easily. 5mm LEDs are too big, so stick with 3mm here. The LED is optional, having it or not does not affect the 'action'. but it's nice to backlight buttons.
