Дълбок анализ на принципа на основната верига на бутонния превключвател

The button switch is a term used in the old standard, and is referred to as a button in the new standard (GB2900·18). The button switch is a low-voltage switch device used to cut off and switch on the control circuit. The rated current of the contact of the button switch is 5A. Therefore, the circuit controlled by the button switch is a small current circuit. 　　

Buttons have single-pole double-position switches or double-pole double-position switches, which are divided into start button, reset button, check button, control button, limit button, etc. according to their kinetic energy and purpose. 　　

Button switches are divided into moving on (normally open) and moving off (normally closed). 　　

Миниатюрните бутони използват проводими гумени или метални листове като проводници и могат да се използват като превключватели за избор на състояние за малки полупроводникови радиостанции, дистанционни управления, детектори за валута и други продукти.
