Combined keying switch device

Abstract

The present invention discloses a combined type key switch device. Said key switch device includes the following several portions: key panel, switch platform, base seat, in which the key panel has four keys, and the switch platform has four contact switches, a cross-shaped pressure lever and its fixing frame. Besides, said invention also provides connection mode of all the above-mentioned portions and the concrete working principle of said key switch device.

Description

technical field [0001] The invention relates to a switch device, in particular to a switch device with a plurality of combination keys. Background technique [0002] The control panels of various electrical equipment in the automobile body are generally equipped with a plurality of key switches, knob switches or other forms of switches that control the operation of its internal components. The control panel of the domain is not compact enough in structure, and the overall design style of the panel is relatively boring and monotonous, which is difficult to satisfy users. Therefore, combining multiple switches into an integrated structure is one of the solutions to the aforementioned problems. However, the combined key switch device also has defects: due to the close distance between the keys themselves, the keys are prone to interference with each other. For example, pressing a key may cause the linkage of another key, resulting in misoperation, especially in The above pheno...

[0002] The control panels of various electrical equipment in the automobile body are generally equipped with a plurality of key switches, knob switches or other forms of switches that control the operation of its internal components. The control panel of the domain is not compact enough in structure, and the overall design style of the panel is relatively boring and monotonous, which is difficult to satisfy users. Therefore, designing a combination of multiple switches into an integrated structure is one of the solutions to the aforementioned problems.

However, the combined key switch device also has defects: due to the close distance between the keys themselves, the keys are prone to interference with each other. For example, pressing a key may cause the linkage of another key, resulting in misoperation, especially in The above phenomenon is more obvious when the number of combined switches is large. For this reason, the usual solution is: in the combined switch device, each key is produced completely independently of each other, and then assembled together through a shell. This structure The defect of the combined switch is: under normal circumstances, the marks on the surface of the key switch with different functions are different, which makes the process of producing and assembling the combined switch more complicated, and the production efficiency is not high, and disassembly, maintenance and assembly are even more complicated. for inconvenience
