Toggle Switches

8S2021-Z is an industrial-grade toggle switch developed by Siemens for applications in various fields. It has a maximum contact rating of 16A and 250VAC, and can be used in tough operating environments with excellent reliability and safety performance. The device is well suited for oil-tight enclosures and is designed to smoothly and reliably operate in temperatures up to 125°C.

Application Field

This toggle switch is suitable for industrial applications in a number of fields. It is most commonly used in permanent installations in switches, electrical control panels, and electromechanical assemblies for automotive, construction, material handling, and other special industry applications. It meets UL and CSA standards, and is also commonly used in residential, commercial, and light industrial applications.

Working Principle

8S2021-Z operates using the basic principle of a standard toggle switch, using a lever to establish an on or off state. When the lever is flipped to the "On" position it completes the circuit by establishing a connection between the two terminals on either side, allowing current to flow. Releasing the lever to the "Off" position breaks the connection between the terminals and stops the current flow.

The 8S2021-Z is configured in the classic toggle switch form with its basic function of connecting and disconnecting electrical circuits. It has a simple, efficient design that offers reliable performance in any application. The toggle switch is constructed from durable components, making it resistant to shock and everyday wear and tear.

Due to its low contact resistance, the 8S2021-Z can be used for single-pole and three-pole applications. It also has a high current carrying capacity and good environmental protection, and is suitable for applications requiring high levels of shock resistance. Furthermore, its snap-acting action ensures consistent and reliable contact performance.

safety Protection

The 8S2021-Z provides an extra margin of safety when used in hazardous locations. It features an insulation treatment that meets UL and CSA requirements, allowing it to meet the highest standards of safety and protection. The toggle switch also features a shutter that guarantees mechanical stability, protecting against accidental contact and shock. Additionally, an optional seal helps protect the switch from dust and ingress.

Conclusion

The 8S2021-Z toggle switch from Siemens offers a reliable, long-lasting solution for a wide range of applications. Its robust design, low contact resistance, high current capacity, and safety features make it an ideal switch for industrial, residential, and commercial needs. With its simple, efficient design, the 8S2021-Z will provide reliable performance for years to come.
