Pushbutton Switches: 8121J81ZGE52 Application Field and Working Principle

Pushbutton switches are electromechanical instruments used to control electric current in a circuit. They are typically operated by a plunger or a lever, but can also be operated by other sources such as a foot pedal or thumb lever. Pushbutton switches are classified into many different types, such as momentary, two or three-position, illuminated, subminiature and industrial. The 8121J81ZGE52 is a type of illuminated pushbutton switch.

Application Field

8121J81ZGE52 is ideally used in a wide range of applications, such as medical equipment, consumer electronics, industrial and automotive control systems, computer and communications equipment. These switches are commonly used in high power applications and are suitable for use in harsh environments. They are also ideal for applications that require extra protection from dust and dirt, such as those in industrial process automation.

Working Principle

The 8121J81ZGE52 operates with the principle of a simple two-state actuation. When the plunger is pressed, it transfers a current through the switch, turning it "on". To turn it "off", the plunger must be released, which causes the switch to open, breaking the current and turning the switch off. This switch is illuminated, making it easier to identify in dimly lit or dark areas. The illuminated section of the switch is filled with a special fluorescent material that causes it to glow when current passes through it. As such, the switch can be easily identified even in darkness.

Conclusion

The 8121J81ZGE52 is an illuminated pushbutton switch that is ideal for a wide range of applications, from medical and consumer electronics to industrial and automotive control. It operates with a simple principle, whereby pressing the plunger results in a current passing through the switch, turning it "on", and releasing the plunger breaking the current, turning it off. The illuminated section of the switch is filled with a special fluorescent material, making it easy to identify in darkness.
