Tiantai Electronics is a leading China membrane switch manufacturer. The membrane switch is composed of six layers: Graphic overlay, overlay spacer, dome retainer, circuit spacer, the lower circuit and the back adhesive. The contact of the upper circuit is downward, and it is in contact with the point of the lower circuit. The circuit contact bounces back after releasing, then the circuit is disconnected and the loop triggers a signal.

The membrane switch keyboard is a popular subcategory of membrane technology, designed for reliability, cost-effectiveness, and ease of use. Constructed from flexible yet durable polyester and polycarbonate materials, the membrane switch is overlaid with legends and graphics for clear, custom labeling. The core function relies on opening and closing an electrical circuit via layered flexible sheets; when a user presses a key, the circuit is completed momentarily, rapidly registering input and minimizing contact bounce issues seen in older mechanical contacts. This type of keyboard is especially common as membrane keypads in household appliances such as washing machines, microwaves, air conditioners, remote controls, and smart home panels, where moisture and dust resistance are paramount. They are also widely used in point-of-sale (POS) systems, kiosks, copying machines, industrial HMI panels, medical devices, automotive consoles, vending machines, printers, and telecommunications equipment, highlighting their extensive role in both consumer and industrial environments. Critical components of a membrane switch keyboard include several precision-made layers, each serving a dedicated purpose to deliver reliable, long-term performance in high-use environments: Graphic Overlay – This uppermost layer forms the visible user interface and is often coated with durable, UV-resistant graphic inks to prevent fading. It is constructed from flexible polyester or polycarbonate for flexibility and longevity, often featuring customized icons, branding, or backlighting window openings for control panel integration. Domes – Domes are integral to tactile membrane keypads, providing a physical response or ‘snap’ when pressed. Plastic (polyester or polycarbonate) is common for most consumer goods, while metal domes are used for higher precision and longer service life. Dome size, shape (such as four-legged, triangular, round, or oblong), and material directly influence tactility, key travel, and actuation force. Spacer – The spacer maintains circuit separation and defines travel distance for each keystroke. It contains punctured holes (die-cut windows) directly beneath each keypad position to permit contact between the overlay and the conductive circuit layer, preserving the reliability of the switch actuation. Circuit Layer – The circuitry, often produced via screen printing (with silver, carbon, or copper-based conductive inks) or photochemical etching, forms the functional heart of the device. Advanced designs may use printed circuit boards (PCBs) for enhanced complexity and durability, allowing for double-layer or multi-layer circuits to accommodate complex functionalities, such as multi-zone lighting or integrated sensors. Circuit Terminal – A flat ribbon cable or flexible tail connects the membrane keypad to the main controller, ensuring quick and secure integration with embedded systems, PLCs, microcontrollers, or PCBs.

Our tactile keypad switch is specifically designed to improve the functionality of electronic scales and ensure that you get precise weighing results every time, this membrane switch with metal dome to make sure the tactile feeling great.
