Component Overview

Ultrasound-console key mats are typically molded silicone or rubber overlays with printed legends, mounted over a snap-dome or membrane-switch PCB. Common failure modes include lost tactile response, cracked silicone around high-use keys (freeze, store, print), and fading of the printed legend. Replacement membranes are matched by console / control-panel part reference; OEM-style parts preserve the original key layout and legend set.
