In industrial environments such as restaurants and cafés (including Starbucks), coffee machines often operate in areas with a high risk of splashes. Since water conducts electricity, contact with electronic components can cause short circuits and system failures—especially in mechanical keyboards. The risk increases significantly if liquid penetrates the internal components of the machine.

Moreover, in kitchen equipment, regular cleaning of the keyboard is essential to ensure both functionality and hygiene. In mechanical keyboards, liquid spills—such as coffee—can cause sticky keys and unresponsive input, hindering daily use.

For these reasons, membrane keyboards are commonly preferred in commercial and hospitality applications. Their sealed construction provides high resistance to splashes and simplifies cleaning. These components are made of permanently bonded layers, which makes them non-repairable in case of damage, but extremely reliable in demanding environments.

As such, membrane keyboards offer an effective and long-lasting solution in settings with high exposure to liquids and dirt, such as food preparation areas, coffee machines, blenders, and other commercial kitchen equipment.

The Thermoplan Mastrena, a super-automatic coffee machine of Swiss origin, is known for its high performance and premium price. That’s why our replacement parts for Thermoplan provide a cost-effective and dependable alternative to keep your equipment running in optimal condition.
