Touch switch is an emerging product of scientific and technological development. He generally refers to a type of wall switch designed using the principle of a touch-sensing chip, which is a replacement for the traditional mechanical button-type wall switch. Touch switches that can be more intelligent and more convenient to operate have the incomparable advantages of traditional switches, and are a very popular decorative switch for home products.
Touch switches are classified into resistive touch switches and capacitive touch switches according to the switch principle. According to the wiring method, they are divided into single-fire wire touch switches and two-wire touch switches (fire wire and neutral wire). From a global perspective, most countries use single-fire wire wiring rules. Therefore, early touch switches were dominated by single-fire control. With the deepening of applications, the stability of zero and hot wire control is higher. The load is greater. The market is dominated by zero and fire control.
Touch wall switches are another successful application of electronics to replace machinery. The touch switch has no metal contacts, does not discharge or ignite, saves a large amount of copper alloy materials, and greatly reduces the requirements for mechanical structure. It directly replaces traditional switches, with comfortable operation, excellent feel, precise control and no mechanical wear. At the same time, the touch switch is more humane. You can choose the text prompts on the switch yourself. The personalized text labels show the effect of the liquid crystal display. The crystal panel emits a faint light. Let people form a sense of orientation and contour.
