{"title":"Cherry MX2A Blue Clicky Mechanical Keyswitch","handle":"cherry-mx2a-keyswitch-blue","url":"/products/cherry-mx2a-keyswitch-blue","description":"This blue MX2A switch gives custom keyboards, replacement builds and embedded human-machine interfaces the classic Cherry clicky feel. It has a tactile bump and a distinct audible click at the actuation point, so each keypress provides clear physical and sound feedback.The MX2A generation refines the original MX design with factory-applied lubrication, an optimised spring and improved housing geometry for smoother key travel, reduced spring noise and a better typing feel. It remains compatible with standard MX keycaps and PCBs.The housing includes a built-in recess for a standard 3mm LED, making it suitable for under-key illumination. For prototyping or simple wiring, pair it with a compatible Cherry MX switch breakout board.Features:MX2A clicky mechanical keyswitchTactile bump with audible clickFactory-lubricated for smoother operationGold crosspoint contactsPlate and PCB mount compatibleCompatible with standard Cherry MX keycapsUpper Housing: CAD-engineered with sub-0.01mm tolerances to ensure precise switching-slide guidance.Two-Part Switching Slide/Stem: This specialised two-part construction features a bulged TLS surface to deliver a distinct audible click sound with tactile feedback at the exact point of actuation.Gold Crosspoint Contact: Self-cleaning, gold-plated triangular cross-contacts meet at precise right angles to provide permanent corrosion protection.Precision Coil Spring: The high-density molecular structure of the spring’s metal alloy is individually calculated and optimised to provide consistent pressure resistance for the switch's specific actuation force.Dual-Functional Housing Base: Engineered from a plastic polymer/glass-fibre blend to serve as both the internal mount for the switching mechanism and the external mounting surface for the keyboard.Built-in recess accommodates a standard 3mm LEDSpecifications:Actuation point: 2.2mmTotal travel: 4.0mmActuation life: Rated for more than 100 million actuationsUpper housing tolerance: sub-0.01mm tolerancesA useful switch for keyboard projects, repairs and physical control panels where audible, tactile feedback is preferred.","vendor":"SparkFun","product_type":"Mechanical Keyswitch","in_stock":true,"options":[],"variants":[{"id":16396,"title":"Default Title","sku":"SF-COM-31672","mpn":"COM-31672","price":4.18,"on_sale":false,"in_stock":true,"available_quantity":96}]}
