About This Category

Keyboard membranes (also called key pads, key overlays, or rubber key mats) are the flexible input layers that sit above the switch matrix on the console's alphanumeric keyboard, control panel, or TGC / mode section. They translate finger press into a switch closure and also seal the underlying electronics from dust, gel, and routine clinical fluids. Membrane replacement is one of the most common preventive-maintenance actions on aging ultrasound consoles, since the elastomer surface wears, delaminates, or loses tactile response well before the electronics behind it fail.
