NSI Industries 79200MS - NSI's NO/NC SPDT Magnetic Reed Switch is a Single-Pole, Double-Throw switch. It draws no power while in the closed position, but when the magnet is applied, the common reed swings from the normally closed state to the normally open contact. When the magnet is removed, the reed contact moves back to the normally closed contact.

Overview

The NSI Industries 79200MS is a Single-Pole, Double-Throw (SPDT) magnetic reed switch designed for reliable actuation. This switch operates by utilizing a magnetic field to change its contact state. In its default, unactuated state, the switch is normally closed (NC). When a magnet is brought into proximity, the internal reed contact swings, opening the normally closed circuit and closing the normally open (NO) circuit. Crucially, the NSI 79200MS draws zero power when in the closed position, making it an energy-efficient component for various control and monitoring applications. When the external magnetic field is removed, the reed contact returns to its original normally closed position, ensuring a predictable and repeatable switching action. This SPDT configuration allows for versatile integration into systems requiring both a normally open and a normally closed contact based on magnetic presence. The SKU for this product is 79200MS, manufactured by NSI Industries. Its UNSPSC code is 39122241. This switch is ideal for applications where simple, reliable, and low-power magnetic sensing is required, such as door/window status monitoring, limit switching, or position sensing in automated systems. The ability to switch between NO and NC states with a single magnetic trigger simplifies wiring and logic in many industrial control scenarios.
