近年来,随着集成电路技术的发展与应用,大大缩小了仪器的体积,进而对仪器面板上的开关、按钮等也要求进一步小型化。为适应这种情况,在一些电子仪器中出现了设计新颖的触模开关。与传统的机械开关相比,它的体积小、工作可靠、寿命长,并且不需要在面板上开很大的安装孔,对一些要求密封防潮的野外仪器很适用。 In recent years, with the development and application of integrated circuit technology, the size of the instrument has been greatly reduced, and further miniaturization of switches, buttons and the like on the instrument panel is also required. In order to adapt to this situation, in some electronic devices appeared in the design of the new touch switch. Compared with the traditional mechanical switch, it is small, reliable, long life, and do not need to open a large hole in the panel, for some of the requirements of the field of moisture-proof sealed instrument is suitable.
