What are the main contents of metal keyboards? For a metal keyboard, it includes a panel, a backing plate, and a plurality of keys. The plurality of keys and the panel are made of metal, and it also includes a heating film that is sandwiched between the panel and the backing plate and adheres to the panel.

The heating film comprises an upper and lower insulating material cladding layer, a conductive metal line layer sandwiched between the upper and lower cladding layers, and at least two pads electrically connected to the conductive metal line layer to connect external circuits.

The metal keyboard also includes a circuit electrically connected to the heating film, and the circuit includes a microprocessor and a temperature sensor connected to the microprocessor. The microprocessor determines whether to feed power to the conductive metal line layer of the heating film based on the detection value of the temperature sensor. By setting a heating film, metal panels and keys can be heated in low-temperature applications, ensuring reliable and flexible operation of the keys.
