The membrane keypad for the Eurobil Stella scale is the replacement part for the waterproof 20-key keypad fitted on the Stella models (bassa and alta) by Eurobil, weight/price/amount scales used in bars, ice-cream shops, bakeries, street vendors, restaurants and trattorias. The rubber membrane seals the keys against liquids and food residue, allowing direct PLU entry, tare, and auto-zero functions even in wet environments.

Replace it when some keys no longer respond to pressing, when key presses become inconsistent due to an oxidised or worn contact beneath the membrane, or when the membrane is torn, stiff, or detached, losing its watertight seal.
