In restaurants and cafés, coffee machines are often used in environments with a high risk of splashes. Water conducts electricity, which can cause short circuits and damage mechanical keyboards. The risk increases if the liquid reaches internal electronic components.

In food preparation equipment like coffee machines, keeping the keyboard clean is essential for both functionality and hygiene. With mechanical keyboards, if coffee is spilled, it’s common for some keys to stick or stop working properly.

For this reason, membrane keyboards are frequently used in sectors such as kitchen equipment, as they are sealed and offer greater resistance to liquids. These keyboards are designed to withstand spills and splashes; their layers are firmly bonded and sealed. However, due to this construction, they cannot be disassembled or repaired easily without damage.

Because of all this, membrane keyboards are the best choice if you need something durable and easy to clean for kitchens or café environments.

And if you're using a Thermoplan Mastrena 1 automatic coffee machine, we've got you covered: we propose a membrane keyboard, part number 107.105 made from high-quality materials, like LEXAN overlay, to ensure long-lasting performance—even in tough conditions.

In addition to membrane keyboards, we also supply a selection of high-wear replacement parts for Thermoplan Mastrena coffee machines, designed to support long-term performance and minimize downtime, such as Grinder Burrs, Thermoplan Mastrena Temperature Probes, Removable Steam Wands.
