Description

Intelligent key switch Technical Field The invention relates to the technical field of switches, in particular to an intelligent key switch. Background Along with the increasing of the living standard of people and the continuous development of the Internet, the wall switch is gradually upgraded by the traditional mechanical switch to become an intelligent key switch, and the intelligent key switch can realize in-situ replacement with the traditional mechanical switch, realize the control and use of multiple scenes of families and meet the requirements of modern home decoration. The working principle of the intelligent key switch is that the relay on the power circuit board is triggered after the key is pressed to the light touch switch in the switch, so that the power on-off of the switch is realized. In the prior art, the key of the intelligent key switch is usually pressed in two modes, one is that one end of the key is fixed through a rotating shaft, the other end of the key is pressed to touch and press the tact switch to realize the power on-off of the switch, and the other is that the middle part of the key is fixed through the rotating shaft, and the upper end or the lower end of the key is pressed to touch and press the tact switch to realize the power on-off of the switch.
