A Bunn 39168 Membrane Switch controls portion selection inputs for reliable and consistent dispensing.
The membrane switch provides the user interface that registers portion selections and sends the correct input to the hot water dispenser for reliable dispensing control. Its sealed membrane-style construction supports consistent response, while also resisting moisture, spills and repeated button use in demanding service environments.
The membrane switch may need replacement if portion buttons respond inconsistently, require extra pressure or fail to trigger the expected dispensing cycle. Physical signs can include worn or lifting overlay sections, while environmental signs may include moisture exposure, heat-related surface damage or residue buildup that could affect button performance.
