Pushbutton switches are used for a variety of applications in both industrial and commercial settings, from signal and hazard applications, to high-security areas. The 8221SDV4GE is an especially effective and versatile pushbutton switch that offers easy installation and reliable operation. This article will discuss the application field and working principle of the 8221SDV4GE.

The 8221SDV4GE is capable of withstanding extreme temperatures, shock, and vibration and is able to function reliably in the most demanding and hazardous fields. Its rugged construction can withstand exposure to hostile chemicals and environments, making it an ideal choice for many applications, including industrial machinery, automotive, and medical devices.

The 8221SDV4GE is designed with a four-pole construction and contact rated voltages of up to 300V. This allows it to be connected to four terminals to create a circuit, allowing it to control and manage power flow. In addition to this, the 8221SDV4GE can be used as a contact switch to detect the opening and closing of a circuit. This function makes it useful for monitoring current flow and providing a means of protection in automotive and medical environments.

The working principle of the 8221SDV4GE is based on the Reed switch. This type of switch uses a magnetic field generated by an external magnet to open and close a contact. When the magnet is absent, the circuit remains closed and when the magnet is present, the contact opens, providing an interrupt to the circuit. The 8221SDV4GE has a built-in magnetic field sensor that can detect the presence and absence of an external magnet, allowing for flexible control over the operation of the switch.

The 8221SDV4GE is a highly reliable and versatile switch, making it an ideal choice for applications in industrial, medical, and automotive settings. Its four-pole construction and contact rated voltages of up to 300V means that it can be used for a variety of different applications. In addition, the built-in magnetic field sensing capability enables the switch to detect external magnets, allowing for more precise control over its operation.
