Abstract

The invention discloses a high stability optical coupling touch switch. The touch switch is characterized in that the touch switch is composed of an optical coupling chip U1, and a current switch chip U3. According to the invention, a user can turn on or turn off a lighting lamp simply by touching different touch pieces. Compared with traditional mechanical switches, the touch switch allows no mechanical friction, has long service life, and effectively avoids the problem of easy damage due to mechanical friction of a mechanical switch.

Description

technical field [0001] The invention relates to a touch switch, in particular to a high-stability optical coupling touch switch. Background technique [0002] At present, household lighting lamps are usually controlled by a mechanical switch, and the power supply of the lighting lamp is controlled to be turned on and off by controlling the conduction and closing of the mechanical switch. However, in the process of using the mechanical switch, it is very easy to be damaged due to repeated operation, which causes great mechanical wear and tear, which brings great troubles to people. In order to solve the above problems, a touch switch has appeared on the market at present, and the human body can control the opening and closing of the lighting lamp by touching the touch switch. There is no mechanical wear and tear of the touch switch, and its life is much longer than that of the mechanical switch. However, the currently used touch switch still has a relatively large defect, t...
