Product Overview
This membrane switch is an OEM component manufactured by Bunn for their beverage equipment lineup, including coffee brewers and iced tea machines. It operates as a normally open momentary contact switch with a push button action. The switch mounts to a panel and uses solder terminals for electrical connection. Its compact dimensions (4 x 6 x 9 inches) allow it to fit into a variety of Bunn machines without modifying the chassis. The membrane design seals the electronics from moisture and debris, improving reliability in busy commercial kitchens. Bunn recommends using only genuine OEM parts to ensure safety and optimal machine performance. The Switch Membrane ITB is controlled via touch and follows the X-10 connectivity protocol, compatible with many Bunn models. Installation requires basic soldering skills and knowledge of the machine's wiring diagram. The plastic housing and metal contact material provide long service life under frequent use. Each unit comes as a single count, so multiple switches may be needed for multi-function panels. Bunn offers this switch as part number 42005, ensuring customers receive an exact match for their equipment.

The Bunn 42005.0000 membrane switch is constructed with a plastic outer housing that protects internal components from spills and dust. The contact material is metal, providing reliable electrical conductivity over thousands of cycles. Its compact dimensions — 4 inches by 6 inches by 9 inches — make it suitable for retrofitting into Bunn machines without requiring panel modifications. The switch uses solder terminals for secure connections, a standard method in commercial appliances.
The membrane top layer is responsive to touch and provides a sealed interface. This design is common in beverage equipment where moisture resistance is critical.
