Abstract

The invention discloses an optical coupling touch switch. The optical coupling touch switch is characterized by being mainly composed of an optical coupling chip U1, a current switch chip U2 and the like. According to the optical coupling touch switch, a human body only needs to touch different touch chips, an illuminating lamp can be turned on or turned off, and compared with a traditional mechanical switch, the optical coupling touch switch has the advantages that no mechanical wear is generated, the service life is longer, and the problem that the mechanical switch is prone to be damaged due to mechanical wear is effectively solved.

Description

technical field [0001] The invention relates to a touch switch, in particular to an 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. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current mechanical switch is easily damaged, and provide an optical coupling touch switch. [0004] The object of the present invention is achieved through the following technical solutions: an optical coupling touch switch mainly consists of an optical coupling chip U1, a current switch chip U2, a field...
