Embodiment Construction

[0026] see figure 1 and figure 2 , the multifunctional button structure 10 includes a movable contact 11 , a fixed contact 13 and a circuit board 15 . The fixed contact 13 is electrically connected to the circuit board 15 and opposite to the movable contact 11 . The movable contact 11 is pressed by an operating button (not shown in the figure), so that the movable contact 11 establishes an electrical connection with the circuit board 15 by contacting the fixed contact 13, so that the circuit board 15 generates a corresponding trigger signal.

[0027] Please also refer to image 3 , the movable contact 11 is in the shape of a dome with one side open and raised toward the opposite side, and has a certain degree of elasticity. The movable contact 11 includes an outer surface 111 , an inner surface 113 and a dome 115 formed by protruding from the inner surface 113 toward the outer surface 111 . A central movable contact portion 1151 protrudes from the inner middle of the dom...

Abstract

The invention provides a multifunctional press key structure. The multifunctional press key structure comprises a circuit board, a moveable contact, a central fixed contact, a first outer side fixed contact and a second outer side fixed contact, wherein the moveable contact and the central fixed contact are arranged on the circuit board; the first outer side fixed contact and the second outer side fixed contact are arranged on the circuit board sequentially and positioned on the outer side of the central fixed contact; the moveable contact comprises a central moveable contact part, an outer side moveable contact part and a normal contact part; when the moveable contact moves towards the direction of the circuit board, the outer side moveable contact part contacts the first outer side fixed contact and the central moveable contact part is separated from the central fixed contact, the circuit board outputs a first trigger signal; and when the outer side moveable contact part contacts the first outer side fixed contact and the central moveable contact part contacts the central fixed contact, the circuit board outputs a second trigger signal.

Description

technical field [0001] The invention relates to a key structure, in particular to a multifunctional key structure applied to portable electronic devices. Background technique [0002] At present, buttons that use movable contacts to complete the trigger function are generally used as switches, such as the camera on / off button of a mobile phone. When the operation button is used to press the movable contact, the movable contact is electrically connected to the fixed contact on the circuit board to realize electrical conduction and switch conduction; when the operation button is released, the movable contact and The fixed contact is separated to realize the switch off. [0003] But above-mentioned button that adopts movable contact to complete the trigger function only has two states of electric on or off, and along with the continuous enlargement of mobile phone display screen and the smaller and smaller size of mobile phone, there are fewer and fewer buttons on the mobile p...
