Pushbutton switches are a type of electric switch. They are either used as on/off switches or indicator signals such as status lights or emergency stops. The PB42G02LNSWNR is a type of pushbutton switch that offers a wide array of applications and uses. In this article, we will take a closer look at the application fields, construction and working principle of PB42G02LNSWNR pushbutton switch.

PB42G02LNSWNR Application Field

The PB42G02LNSWNR pushbutton switch is a two-pole, two-position, latching pushbutton switch. It is used for applications where the appliance needs to be powered continuously, such as security systems, telecommunication systems, and industrial control systems. This switch is ideal for any type of environment since it is resistant to dust, liquid and oil. It is suitable for use in 20-40VDC/24VAC circuits, and can also be used in low-voltage applications thanks to its UL10C certificate.

PB42G02LNSWNR pushbuttons are popular in home automation applications, as they are easy to operate and reliable. They are suitable for controlling lights, curtains, garage doors, gates, and other automated devices. The switch is also found in electronics equipment, security systems, fire alarm systems, and other telecommunications equipment. It is also used in machines, electrical appliances, fuel pumps, and automotive applications.

PB42G02LNSWNR Construction

The PB42G02LNSWNR is a compact, lockable pushbutton switch. It is constructed with a zinc alloy die-cast housing and silver contact surfaces. The housing features a circular shape with two-position switches that are well marked for easy identification. The switch has a latching mechanism for sustained power to the appliances when activated. It also has a standard operating depth of 4 mm and a contact bounce of less than 3ms. The switch has a maximum switching current of 10A and a maximum carrying current of 30A.

In addition, the switch has a silver-plated air contact, which has excellent conductivity and helps to reduce contact resistance. The silver contact also helps to increase the service life of the switch. Furthermore, it features a silicon rubber terminal seal base which protects the device from dust, water, and other hazardous contaminants. It also has a standard operating temperature range of -40℃ to 85℃.

PB42G02LNSWNR Working Principle

The PB42G02LNSWNR has two positions – the on position and the off position. When the switch is in the off position, the circuit is closed and no current flows through. To turn on the switch, the button must be pushed down. This causes the latching mechanism to be activated, which creates a contact between the contacts inside the switch and the circuit is then open. This allows current to flow through the switch and the appliance being controlled is then powered up.

When the button is released, the latching mechanism is deactivated and the switch remains in the on position. The switch stays in the on position until the button is pressed again. This causes the contacts to be closed and the circuit is disrupted, and the appliance is then powered off.

Overall, the PB42G02LNSWNR is an ideal choice for any switch application. It is versatile, reliable and capable of handling a wide range of applications. Its latching mechanism provides a secure connection and prevents unintended power offs, ensuring the safety of the equipment and personnel. In addition, its construction is dust-proof and oil-resistant, making it suitable for use in harsh indoor and outdoor environments.
