The LSN4L (Linear Stationary Non-Contact 4 Limit) is a type of snap action limit switch. It is a specialized mechanical device used to control a circuit when the opening or closing of a door, window, or other type of opening is detected. It was designed to provide reliable operation in environments where conventional limit switches may not be suitable. It can also be used in other applications such as industrial automation, motion control, door activation, and security systems.

The LSN4L consists of two main components: the base unit and the switching unit. The base unit is a metal block that attaches to the mounting surface, typically a wall or door frame. A cover is included with the base unit and is used to protect the switch from dirt and moisture. The base unit also includes an adjustable bracket that allows for easy installation and mounting.

The switching unit includes two electrical contacts, two magnets, and a plate. The two electrical contacts are used to complete the circuit when the magnets are brought together. The magnets within the switching unit are arranged in two rows and are separated by a plate. The plate acts as an insulator to limit the flow of current between the two contacts. The magnets align with each other when the door or window opens, which causes the plate to move away and the contacts to close. When the door or window closes, the magnets become misaligned, which causes the plate to move back into position and the contacts to open. This motion detects the movement of the door or window and completes the circuit.

The LSN4L offers many benefits compared to conventional limit switches. It is cost effective, requires no wiring or modifications, and is maintenance free. It is also more reliable than other types of switches because of its non-contact design, and it is resistant to dirt and moisture.

The LSN4L is a versatile and reliable solution for a wide range of applications. It is commonly used in industrial automation, motion control, door activation, and security systems. It can be used to detect when a door or window is opened or closed, or to detect movement in a system. It is also used in other applications where reliability and low maintenance are of paramount importance.
