LF Push-Button Panel Membrane for Coffee Machines

A push-button panel membrane replaces the touch-sensitive interface on commercial coffee machines, converting finger pressure into electrical signals that start and stop the brewing cycle. The membrane sits beneath the outer panel, sealed against moisture and steam. Each button corresponds to a specific function—espresso, steam, hot water, or programme selection—so the operator can select the desired output without opening the machine.

To use the membrane, the operator presses the button firmly until it clicks. The click confirms the circuit is closed and the command is sent to the machine's control board. No tools or calibration are needed; the membrane is a direct drop-in replacement for the original part.

The membrane is constructed from a flexible polymer layer printed with conductive ink pathways. These pathways connect to a ribbon cable that plugs into the machine's control board. The outer surface is smooth and wipe-clean, resisting the build-up of coffee oils and steam condensation that can interfere with operation over time.

This 5-button membrane is designed to fit Pavoni and Bar commercial coffee machines. It restores the original control layout and functionality, ensuring the machine responds to each press as intended.

Cleaning is limited to wiping the surface with a damp cloth and mild detergent. Avoid solvents or abrasive pads, which can damage the printed circuits and shorten the membrane's service life.

The catalogue places this part under Coffee Machine Spares, Membrane Switches.
