The pushbutton switch (like the PS9-143B) is a mechanical device used to control the flow of electricity. They are made of a number of components including a single or multiple contacts, a switch body, and a lever or knob. These components vary depending on the application, and can range from small, miniaturized switches to larger, more robust switches.

The purpose of the pushbutton switch is to isolate one circuit from another, as well as open or close a circuit when a button is pushed. The contact in the switch is either normally open (NO), normally closed (NC), or changeover (CO). When the button is depressed, the contact inside the switch physically moves and either opens or closes the connection of the circuit.

Pushbutton switches are commonly used in a variety of applications including automotive, industrial, home automation, and commercial. Automotive pushbutton switches are generally used to control engine functions, such as ignition and starter systems. Industrial pushbutton switches are commonly used to control machinery, and can also be used in safety systems. Home automation applications often use pushbutton switches to control lighting, HVAC, or security systems. Commercial pushbutton switches are used to control various types of equipment.

The PS9-143B is a standard mini pushbutton switch, and is used in a variety of applications. It is a NO/NC switch, meaning that the contact is normally open but can be closed when the button is pressed. The contacts are rated for AC and DC voltages up to 30V, and have a current rating of 2A. The switch body is constructed of molded plastic and the lever is nickel plated. It is a single pole, single throw switch, which means only one contact is inside the switch.

The working principle of the PS9-143B is simple when the button is pressed, the internal contact moves and closes the connection of the circuit. This allows electricity to flow through the circuit and activates whatever device or system is connected to it. Conversely, when the button is released, the connection is broken and the circuit is no longer powered.

Pushbutton switches are versatile, reliable, and easy to use. They offer a simple, straightforward way to control the flow of electricity, and are well-suited for a variety of applications. The PS9-143B is a robust switch that can easily handle high-voltage, low-current circuits and is suitable for a variety of uses.
