Pushbutton Switches

Pushbutton switches are the most common type of switch and can be found in a wide variety of applications. A pushbutton switch is a type of switch that is activated by pushing a mechanical button. Pushbutton switches range from simple momentary contact switches to more advanced switches that offer multiple functions and light/sound indicators.

The PB22G02LXNS is a two-pole pushbutton switch from NKK Switches. This switch is suitable for various applications including control and signaling in industrial, commercial, and consumer applications. The PB22G02LXNS operates using a momentary contact; when the pushbutton is pressed, a circuit is created, and when it is released, the circuit is broken. Depending on the configuration, this contact can be normally open (NO) or normally closed (NC), and can achieve ratings up to 5A 125 Vac/48 Vdc.

PB22G02LXNS Application Field

The PB22G02LXNS has a broad range of application fields depending on the different configurations and how it is wired. It is commonly used in industrial applications for control and signaling, such as elevator controls, as well as industrial machines. In commercial applications, the PB22G02LXNS is often used for status indication and input taking control of such as lightings, air conditioning, and audio/video systems. In consumer applications, the PB22G02LXNS is often found in everyday household items such as washing machines, cell phones, and video game consoles.

PB22G02LXNS Working Principle

The PB22G02LXNS features a two-way contact system, meaning when the pushbutton is pressed, a circuit is created, and when it is released, the circuit is broken. This contact system is earthed and there is a diode between the two contacts, which act as a spark-choke for the gap. This spark-choke stops sparks from forming within the switch and ensures the contacts close and open properly.

The contacts are activated by the movement of a contact arm. When the pushbutton is not pressed, the contacts are closed and a circuit is created. When the pushbutton is pressed, the contact arm is moved and the contacts open, breaking the circuit. Depending on the configuration, this contact could be normally open (NO) or normally closed (NC).

The PB22G02LXNS also features an audible click when the switch is pressed. This click is created by the contact arm deforming a contact point. This click can be used as an indicator that the switch has been activated. This audible click can also be disabled by pressing the pushbutton switch gently.
