Liquid spills are among the most common causes of keyboard failure in foodservice environments, especially in food preparation equipment like coffee machines. Mechanical keyboards are not built to withstand exposure to water, coffee, dust, or food particles. In contrast, membrane keyboards are engineered with sealed layers that provide effective protection against splashes and contaminants.

While membrane keyboards are designed for durability, prolonged daily use can lead to the gradual degradation of the internal rubber or silicone membrane. When replacement becomes necessary, both quality and compatibility are critical.

We offer membrane keyboards specifically designed for Thermoplan Mastrena coffee machines, fully compatible with OEM part number 107.104. Manufactured with high-quality materials, our keyboards have been rigorously tested by service professionals from leading restaurant chains—including Starbucks—to ensure outstanding performance, durability, and peace of mind in demanding operational environments.

Note: Ensure that the surface to which the keypad is applied is clean and free of debris prior to membrane switch installation.

We also invite you to explore our range of commercial kitchen equipment spare parts, especially high-wear components for Mastrena coffee machines, such as grinder burrs and the steam wand, temperature probe - 40500.1866. We offer high-quality commercial kitchen parts to keep your equipment operating at peak performance.
