Acrylic chest tags are a common form of identity identification, mainly made of acrylic sheet, which has the characteristics of high transparency, strong customizability, and good weather resistance. Acrylic chest tags are usually composed of acrylic sheets, iron tags, backboards, and double-sided tape. Acrylic board is the main material for Acrylic chest tags, with characteristics such as high transparency and weather resistance, and can be customized according to different needs. Iron plaques are usually made of metal materials and can be engraved with employees' names, positions, company names, and other information. The backboard is used to secure the chest badge to clothing and is usually made of plastic or metal material. Double sided tape is used to stick backboards and iron plates.

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.

Tiantai Electronics is China manufacturer and supplier who mainly produces tactile switch keypad with many years of experience. Tactile membrane keypads are momentary contact switches, meaning they are only active while being pressed. Tactile keypads provide physical feedback to the user through a metal dome or formed plastic dome beneath the overlay.

In the filed of modern electronic components, the gold-plating metal dome membrane switch has emerged as a crucial element, widely used in various electronic devices.

Tiantai Electronics is a leading China capacitive touch membrane manufacturer. A capacitive membrane switch is a touch sensitive switch that activates when the user makes contact with the sensor. The membrane switch uses capacitive sensing technology to perform the functions of a traditional membrane switch with a simple, light touch.
