It is suited to builds where you want a smooth, direct keypress without a tactile bump or audible click.The MX2A generation refines the classic Cherry MX design with factory-applied lubrication, an optimised spring and improved housing geometry. This helps deliver smoother key travel, reduced spring noise and a typing feel that remains compatible with standard Cherry MX keycaps and PCBs.The housing includes a built-in recess for a standard 3mm LED, making it easier to add under-key illumination in your own keyboard or control panel design. For prototyping, it can also be paired with a matching switch breakout board for simpler wiring.Features:MX2A linear mechanical keyswitch: Designed for custom and replacement keyboards, as well as embedded human-machine interfaces.Smooth, uninterrupted keystroke: Linear action with no tactile bump or audible click.Factory-lubricated: Provides smoother operation.Gold crosspoint contacts: Self-cleaning, gold-plated triangular cross-contacts provide permanent corrosion protection.Plate and PCB mount compatible: Suitable for standard keyboard mounting approaches.Standard Cherry MX keycap compatible: Works with standard Cherry MX keycaps.Upper Housing: CAD-engineered with sub-0.01mm tolerances to ensure precise switching-slide guidance.Linear Switching Slide/Stem: Engineered to control pre-travel and keystroke feel, featuring a straight TLS surface that delivers direct triggering and the signature linear characteristics of the MX Red.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.LED recess: Built-in recess accommodates a standard 3mm LED.Specifications:Actuation point: 2.0mmTotal travel: 4.0mmActuation lifespan: Rated for more than 100 million actuationsA solid choice for keyboard enthusiasts, game controllers, macro pads and maker projects that need a reliable, smooth mechanical switch. **Product Type:** Mechanical Keyswitch ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD4VYDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--137ac6c636bb5fbcf1041d8cadbfae93fd93bddc/31671-Cherry-MX2A-Keyswitch-Red-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD41YDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--5903d25e54ffb21eec71553c55d0eab1fe1dc107/31671-Cherry-MX2A-Keyswitch-Red-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD5lYDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ab3c0f142655bf63b2c6b29b7aa506164542e642/31671-Cherry-MX2A-Keyswitch-Red-Side.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD6FYDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--8a3dd0cbf47a9686603fb4f9afe835563a41702e/31671-Cherry-MX2A-Keyswitch-Red-Back-2.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkD61YDSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--561526323d3bf59ad965af1b4925f139cf935c92/31671-Cherry-MX2A-Keyswitch-Red-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).
