Abstract:
Disclosed are a key, a switch assembly, a signal transmitter and a signal transceiving system. The signal transmitter comprises: a control panel, a bottom housing, a sealing piece and the key; the sealing piece cooperates with the key and the bottom housing to form a sealing cavity; the control panel is located in the sealing cavity, and the control panel is connected to a switch part; and a thin-walled region of the key abuts against and triggers the switch part when subjected to an external force. The key is divided into the thin-walled region and a thick-walled region; the thickness of the thin-walled region is less than 2 mm, the ratio of the area of the thin-walled region to the thickness is greater than 1177.5 mm, and deformation variables can be generated under the action of the external force; and the thick-walled region is used for fixing the key. The signal transmitter has a simple overall structure, is convenient to operate, and is easy to disassemble and assemble. It is convenient for a user to replace or repair internal parts thereof, and the signal transmitter clamps tightly, is not prone to loosening, and has a good waterproof and dustproof performance.
