multi-directional switching device

Abstract

A button assembly comprises an insulation body, a first contact terminal, a second contact terminal, a third contact terminal, a first movable terminal, a second movable terminal and a pressing piece, wherein the first contact terminal, the second contact terminal and the third contact terminal are fixedly held in the insulation body; the first movable terminal is located above the first contact terminal; the second movable terminal is located above the second contact terminal; and the pressing piece can act on the movable terminals. The pressing piece is installed on the insulation body. The pressing piece comprises a pressing portion and an embossment portion which is protruded towards a movable terminal direction, wherein two ends of the pressing portion are extended so as to exceed the insulation body. When a force is applied to the pressing portion, the pressing portion drives the embossment portion to move towards the movable terminal direction. When the first movable terminal is pressed by the embossment portion and then is connected to the corresponding first contact terminal, at this time, the first contact terminal is connected to the third contact terminal. When the second movable terminal is pressed by the embossment portion and then is connected to the corresponding second contact terminal, at this time, the second contact terminal is connected to the third contact terminal.

Description

【Technical field】 [0001] The invention relates to a key assembly, in particular to the position of the key in the key assembly. 【Background technique】 [0002] For the prior art related to the present invention, please refer to the Chinese patent whose publication number is CN103474275. This patent discloses a side button assembly, which includes a switch mounted on a circuit board, a side button that can be pressed against the switch, and a stopper that can block the side button. The mounting part on the circuit board and the blocking surface perpendicular to the mounting part, the side button is provided with a raised part aligned with the switch, the distance from the blocking surface to the side button is greater than the distance from the switch to the side button, and the side button is first in contact with the switch The design of holding the stop part on the circuit board by screws is more complicated in structure, and because the installation part of the stop part...

This patent discloses a side button assembly, which includes a switch mounted on a circuit board, a side button that can be pressed against the switch, and a stopper that can block the side button. The mounting part on the circuit board and the blocking surface perpendicular to the mounting part, the side button is provided with a raised part aligned with the switch, the distance from the blocking surface to the side button is greater than the distance from the switch to the side button, and the side button is first in contact with the switch The design of holding the stop part on the circuit board by screws is more complicated in structure, and because the installation part of the stop part is perpendicular to the stop surface, the stop surface is easily deformed due to excessive force, so the side When the key presses the switch, it is also easy to change the vertical angle between the blocking surface and the installation part, and the function of the stopper part disappears.
