Working Principle

The working principle of the PV4F2B0SS-301 pushbutton switch is fairly simple. The switch contains three terminals: a common terminal, a normally open terminal and a normally closed terminal. When the button is in its neutral position, the common terminal is connected to the normally closed terminal. When the button is pressed, the contact between the common terminal and the normally closed terminal is broken and the normally open terminal is connected to the common terminal. When the button is released, the contact between the common terminal and the normally open terminal is broken and the normally closed terminal is connected to the common terminal.
