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. **Product Type:** Mechanical Keyswitch ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD81YDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--f8db3dc5ea83c4a06e082af063ce270915804b0f/31672-Cherry-MX2A-Keyswitch-Blue-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD9FYDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--bdd00ed22045fd617633f414fa9e11701b1992a4/31672-Cherry-MX2A-Keyswitch-Blue-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD9VYDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--b05193db75080151aab870185d5728c0d3d9d382/31672-Cherry-MX2A-Keyswitch-Blue-Side.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD9lYDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--39a38d7edd5aa1f13332d23b8307da39bbb4fe92/31672-Cherry-MX2A-Keyswitch-Blue-Back.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD91YDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--772ae1153fd0d8788331ade077c9df4978d859c6/31672-Cherry-MX2A-Keyswitch-Blue-Scale.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
