Abstract

A push button assembly for use in an electronic device includes a plate, a circuit board, an elongated button and an elastic element. The plate is arranged within the electronic device. The circuit board is fixed to the plate. The circuit board includes a switch. The elastic element is fixed to the plate. The elastic element includes an elongated depressible portion arranged between the circuit board and the button. The depressible portion extends along a lengthwise direction of the button and is deformable by depression of elongated button. The disclosure also provides an electronic device having the push button assembly.

Description

technical field [0001] The invention relates to a key device and a portable electronic device using the same. Background technique [0002] In the existing keys, the function of the key is usually activated by directly pressing the DOME (switch assembly). For a long button, if a DOME is used, there is a big difference in the feel between pressing a position farther from the DOME and pressing a position closer to the DOME, which easily makes the user mistakenly think that the button is not pressed correctly. Contents of the invention [0003] In view of this, it is necessary to provide an improved elongated button device to solve the above problems. [0004] An electronic device, which includes a key device and a main board, the key device and the main board are electrically connected through a flexible circuit board, the key device includes a substrate, a circuit board and a key body, the substrate is fixed In an electronic device, the circuit board is arranged on the su...
