Abstract

The invention relates to an electrostatic induction switch, comprising an electrostatic inductor, a capacitor, a signal processing circuit, a switch circuit and a power supply; the electrostatic inductor is respectively connected with one end of the capacitor and the input end of the signal processing circuit, the other end of the capacitor is grounded, and the output of the signal processing circuit The terminal is connected to the input terminal of the switch circuit; the electrostatic sensor induces static electricity when the electrostatic body enters the sensing range, the capacitor stores the static electricity and generates a voltage signal, the signal processing circuit preprocesses the voltage signal, and the switch circuit realizes communication according to the preprocessed voltage signal off, the power supply supplies power to the signal processing circuit and the switching circuit. The invention is based on the principle of electrostatic induction, can control the on-off of the circuit according to the static electricity, does not need to make a sound, is not easily disturbed by the external environment, and has the characteristics of energy saving, small size, low cost and easy use.

Description

technical field [0001] The invention relates to the field of switches, in particular to an electrostatic induction switch. Background technique [0002] At present, there are many sensor switches, such as voice-activated switches, infrared sensor switches, etc. Among them, the voice-activated switch must have a certain volume before it can be turned on, and it must be turned off after a while, which will bring inconvenience to the user. Moreover, the voice-activated switch is easily disturbed by sound and malfunctions; the infrared sensor switch must have a certain amount of infrared heat source (such as the heat emitted by the human body) before it can be opened. When the heat of the human body is insulated by thick clothes, it is easy to make the switch inoperative. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electrostatic induction switch for the defects of the existing induction switch. [0004] The ...
