Snap action switches, also called limiting switches, are electromechanical devices that are used to actuate relays, make and break circuits, or actuate overload protection devices when a certain threshold value is exceeded. The switch is actuated by mechanical movement of an actuator to a set point which, in turn, causes the switch contacts to make or break an electrical circuit. The switch is normally spring loaded and typically consists of two parts - a switch body and a sliding actuator. The switch body has two actuator travel points (limit points) which correspond to two electrical connections. When the actuator reaches one of these two points, the switch contacts are open or closed, respectively. The D4NL-4EDG-B4 is an industrial grade snap action switch from Omron. It is designed for use in control panels and power supplies, and is ideal for controlling motors, pumps, and other heavy-duty industrial machinery.

The D4NL-4EDG-B4 has two types of actuators – plunger and cross-roller – each with different operation characteristics. The plunger actuator works on the principle of compression, while the cross-roller actuator works on the principle of friction. Both types of actuators have a reliable, accurate response when reaching their preset limit points, while the plunger type is usually more responsive. In addition, the D4NL-4EDG-B4 has a longer life cycle and greater reliability compared to other snap-action switches due to its superior construction.

The D4NL-4EDG-B4 has a metal base and a robust plastic housing, making it resistant to dust, oil, chemical vapors, and other contaminants. It also has a low current rating of only 1.75A, making it suitable for controlling low-power devices. Its important components, such as the contacts and actuator, are also highly durable and can withstand a wide range of temperatures.

In order to use the D4NL-4EDG-B4 switch, it must be connected to a device or a circuit. First, the actuator must be set to make contact when it reaches the limit points. This can be done by using the two adjustment screws on the top of the switch body. Then, the switch body can be mounted onto its surface or bracket using screws or rivets. The switch contacts should then be connected to the desired device or circuit. Once the connection is made, the switch will actuate when the preset limit points are reached.

The D4NL-4EDG-B4 is an industrial grade snap action switch that is ideal for industrial applications. It features a reliable, accurate response when it reaches its set limit points, and a long life cycle and greater reliability thanks to its superior construction. In addition, it is also highly resistant to dust, oil, chemical vapors, and other contaminants, and is suitable for controlling low-power devices, making it an ideal choice for industrial applications.
