The FMSMMB2068M is an integrated magnetic switch with multiple applications in various fields and industries. The device features a solid-state magnetic switch built with a MOSFET plus an integrated relay for a wide variety of switching scenarios and applications. It contains two independent magnetic poles that are normally-closed when not energized, a red LED indication light for visual alerts, and a power terminal for an operating current of up to 3A. The device is resistant to both reverse voltage polarity and reverse current, making it the perfect choice for industrial and domestic applications.

The main application fields of the FMSMMB2068M can be divided into automotive, industrial, marine, security systems, and domestic. In automotive applications, the switch provides an additional safety feature to an ignition system. Additionally, the device can be used to monitor the status of a fuel pump and let the user know when something has gone wrong. In industrial applications, the device is used to control motors, pumps, valves, and other machinery that requires external assistance to turn on or off. The switch can also be used to shut down an entire production line in the event of a fault.

In marine applications, the device can be used as part of an engine\'s emergency shutdown system, as well as to indicate when a bilge pump is turned on or off. In security systems, the switch can be used to monitor the status of doors, windows, and other entry points to ensure that they are closed and secure. Finally, the FMSMMB2068M can also be used for domestic applications such as door closers and safety sensors for kitchen appliances.

The working principle of the FMSMMB2068M is straightforward. When the device is supplied with the proper voltage, a coil inside the device is energized and creates a magnetic field. This field attracts the two internal poles, and when they touch, they close the switch. When the voltage is removed, the coil\'s magnetic field dissipates, and the two poles separate, opening the switch.

When the FMSMMB2068M is used in automotive applications, it is usually connected to an ignition switch. When the ignition is off, the switch is open and will not allow the vehicle to start. When the ignition switch is turned on, the magnetic coil will be energized, thereby closing the switch and allowing the fuel pump to be powered. When the switch opens, the fuel pump will be shut down as well.

In security applications, the switch is generally connected to a door monitor. When the door is closed, the switch will be closed and the monitor will indicate that the entry point is secure. If the door is opened, the switch will open and the monitor will alert the user of the open door.

The FMSMMB2068M is a versatile device that can be used for a wide variety of applications in automotive, industrial, marine, security, and domestic settings. Its simple yet effective working principle makes it the perfect choice for a variety of scenarios, allowing users to stay safe and secure.
