Premium Quality Keyboard Membrane for 16K/48K Rubber Key Models
If your vintage computer is suffering from unresponsive keys or a completely dead keyboard, the membrane is usually the culprit. Our UK-made replacement keyboard membranes are manufactured to high standards, providing a tactile and reliable solution to bring your hardware back to life. These are brand-new components, designed to replace the ageing, brittle membranes found in original 1980s hardware.
Extensive Compatibility: ZX Spectrum and Clones
While designed specifically for the iconic Sinclair ZX Spectrum 16K and 48K (rubber key models), the versatility of this membrane makes it an essential part for many international variants and clones.
This membrane is a confirmed fit for:
- Timex Sinclair T/S 1500: The upgraded American ZX81 clone that uses the Spectrum-style rubber key case.
- Microdigital TK85 & TK90X: Popular Brazilian clones that rely on this specific membrane layout.
- CZ-2000: The Argentine version of the Spectrum.
- Most 16K/48K Clones: Any machine utilising the standard 16K/48K rubber key matrix.
Why Choose a UK-Made Replacement?
Not all membranes are created equal. By choosing a UK-manufactured part, you are ensuring:
- Precision Engineering: Exact fit for the internal mounting pillars.
- Durable Connector Tails: Enhanced flexibility to prevent the cracking common in older designs.
- High Conductivity: Premium conductive inks for instant key registration.
Installation and Maintenance Tips
Replacing your membrane is a straightforward process that requires only a screwdriver and a little patience. Ensure that the internal connectors are clean before seating the new tails. Because these membranes are newly manufactured, they offer a significant lifespan increase over “new old stock” parts that may have degraded in storage.
Please Note: This membrane is intended for rubber key models only and is not compatible with the ZX Spectrum+ (plus) or 128K “Toastrack” models.
