Abstract

The invention provides an electronic delay microswitch which comprises a 9V direct-current power source, a touch electrode CM, a non-stable trigger circuit and a level output terminal. The electronic delay microswitch is characterized in that the model of a quad 2-input NAND gate circuit IC1 in the non-stable trigger circuit is CD4011. The electronic delay microswitch avoids abrasion of non-mechanical parts and especially suitable for being used in places where normal mechanical microswitches are unsuitable for being used, and electronically replaces a circuit of the mechanical microswitches, defects of the mechanical microswitches are overcome, and circuit operating states are controlled by touching the touch electrode with fingers. In addition, the electronic delay microswitch has a precise delay function which is irreplaceable by the normal mechanical microswitches, and the level outputted by the electronic delay microswitch can directly drive control circuits of light, electricity, thyristor and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic automatic control, and relates to an electronic micro-delay switch. Background technique [0002] The electronic micro-delay switch of the present invention has no wear of mechanical parts, and is especially used in places where ordinary mechanical micro-switches are not suitable, such as in the environment of frequent use or dust or dust. Mechanical micro switches are not easy to use in combination with instruments and automatic control circuits. The electronic micro-delay switch of the present invention replaces a circuit of the mechanical micro-switch with an electronic method, overcomes the defects of the mechanical micro-switch, and uses fingers to touch the touch electrode on the circuit to control the working state of the circuit , and also has a precise time delay function, which is irreplaceable for ordinary mechanical micro switches. The core component used in this electronic micro-...
