What is a Pushbutton?。
A pushbutton is a type of button that is activated by pressing it down.

The pushbutton typically consists of two parts: the button cap and the switch mechanism. The button cap is the part that is pressed by the user, while the switch mechanism is the electrical component that is activated when the button is pressed.。
The switch mechanism in a pushbutton can be of various types, but the most common one is the single-pole single-throw (SPST) switch. This type of switch has two contacts – the normally open (NO) and the common (COM) – which are connected when the button is pressed. When the button is released, the contacts are disconnected, and the circuit is broken. Other types of switches can also be used in pushbuttons, such as the double-pole single-throw (DPST), which has two NO and two COM contacts.。
Applications of Pushbutton。
