Pushbutton switches

Buttons

— button — a point pressure surface, when exposed to which the electrical circuit closes, including the current consumer. The return of the button is most often implemented due to the spring mechanism — by removing the finger from such a button, the contact automatically opens, turning off the power. Pushbutton switches are used to control bells, as well as to turn on the drive on roller shutters / blinds, gates, etc. That is, the button is used where it is necessary to turn on the current consumer for a short time, without fixing the switched on position. Additionally, the switch button can be implemented by a reciprocating mechanism with fixation in several positions: the first pressing of the button statically closes the electrical circuit, and a second pressing is necessary to open the circuit. Pushbutton switches of this type work as keyboard electrical accessories, that is, the contact / disconnection of the circuit can be fixed.
