Description

TECHNICAL FIELD

[0001] The utility model relates to a spring piece, especially a circular spring piece applied to a tactile switch key. BACKGROUND

[0002] The tactile switch is a small electronic switch widely used in various electronic devices. When the user applies sufficient operating force to make the switch reach the closed state, the circuit will be connected. Once the user removes the applied pressure, the switch will be immediately disconnected, thereby cutting off the circuit, which only needs slight touch to complete the on-off operation. The tactile switch mainly relies on the deformation of the metal spring piece under pressure to realize the on-off function of the circuit. The components of the tactile switch include an insert, a base, a spring piece, a button and a cover plate. The insert is usually used to fix the position of the switch. The base is the support structure of the entire switch. The spring piece is the core component to realize the switch function. The button is the interface for user operation. The cover plate can protect the internal structure.

[0003] The main function of the spring piece is to provide elastic force and ensure the tightness of the connection. However, in actual application, due to the shape and structural characteristics of the spring piece, it is easy to deviate during assembly or use, which affects the stability and service life of the tactile switch.
