Abstract

A press key set is set on a circuit board of an electronic device including a shell, a light conductor, an elastic actuating unit, a luminous mode set and a switch, among which, the mode includes a light diode and a flexible CB, one end of which is soldered with the light diode and housed in the light conductor after fixedly connected with the actuating unit, the other is welded to the CB having a switch. The manufacturing method includes: providing a shell, a light mode set and a switch to assemble the above mentioned parts on the CB of the electronic device.

Description

【Technical Field】 [0001] The invention relates to a button and a manufacturing method thereof, in particular to a button applied to a portable electronic device and a manufacturing method thereof. 【Background technique】 [0002] For prior art related to the present invention, please refer to US Patent No. 5,747,756 published on May 5, 1998. The key disclosed therein includes a bump, a light-emitting layer, an excitation layer, and a transparent layer. The backlight is provided by the light-emitting layer, which covers the excitation layer and the circuit board. The excitation layer is provided with convex pillars, which pass through the holes on the light-emitting layer and extend to the transparent layer on the surface of the keyboard. The convex post on the excitation layer functions as a light pipe to guide light from the light-emitting layer. However, the protruding pillars disclosed in the prior art are all soldered on the same circuit board. When the keys are pressed, the k...
