Anàlisi profunda del principi bàsic del circuit de l'interruptor de botó

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). 　　

Els botons en miniatura utilitzen cautxú conductor o làmines de metall com a conductors i es poden utilitzar com a interruptors de selecció d'estat per a petites ràdios de semiconductors, comandaments a distància, detectors de moneda i altres productes.
