U18J3V4QE2

Rocker Switches

U18J3V4QE2 is a type of rocker switch for industrial use, and is suitable for applications such as panel control, machine control and home appliances. It comes with a variety of mounting options depending on the required application. This rocker switch has three terminals, and it is designed to be used in two-way switching, either normally open (NO or "on") or normally closed (NC or "off").

Application Field

This U18J3V4QE2 rocker switch is designed for a wide range of applications, ranging from industrial control and motor control to household appliances. It can also be used to switch on and off circuits, with its two contact poles. This rocker switch also has various features, such as contact protection, surge suppression, dust protection, etc.

In addition, this switch is suitable for applications that require vibration and shock protection, such as elevators, escalators, and other industrial machinery. This rocker switch has a high electrical contact rating, so it can be used for higher power applications. It is suitable for controlling things such as lighting and motors, and its built-in features eliminate the need for external surge suppression.

Working Principle

Generally speaking, the U18J3V4QE2 rocker switch is actuated by a rocker or lever that applies mechanical force to its metal contacts. The contacts are usually made of metal, and when the metal contacts touch, an electrical circuit is completed and a connection is made. Depending on the position of the rocker switch, the electrical connection can either be opened or closed, allowing the current to pass from one side to the other.

When the switch is in the off position, the lever or rocker will be in the lowest position. When actuated by a certain force, the lever or rocker moves up and down through a pivot point, and the metal contacts move with it. When the contacts touch, an electrical connection is made and the current can pass through. When the switch is in the on position, the metal contacts will close and the current can flow through.

The U18J3V4QE2 rocker switch is extremely easy to use and is reliable under normal conditions. It is suitable for applications that require a high level of power and is perfect for use in situations where a high electrical current is required. It is also versatile enough to be used in diverse applications and is designed to be used in two-way switching.
