Pushbutton Switches have a long history of being used for user input, ranging from doorbells to the alarms in a missile defense system. Likewise, the 8121SD2AGE Pushbutton Switch is an essential component to a wide range of automated machinery and equipment. Knowing the application fields and its working principle can aid in faster troubleshooting, maintenance and repairs.

Application Fields

The 8121SD2AGE Pushbutton Switch is found in everyday products, such as cell phones, televisions, microwave ovens, and even refrigerators. It is especially used in communications and Wi-Fi network devices, electronic games and toys, and in industrial automation, such as digital control panels and programmable logic controllers (PLCs).

The 8121SD2AGE Pushbutton Switch is also used in aerospace and military systems, from unmanned aerial vehicles (UAVs) to satellites. It is also utilized in laboratory and engineering inspection systems, instrumentation, and advanced medical equipment.

Working Principle

The 8121SD2AGE Pushbutton Switch has a contact sheet composed of three layers: one is the surface sheet where the actual pushbutton is located, while the other two are insulation layers that provide electrical insulation between the contact sheet and the circuit board. When a user presses the pushbutton surface sheet, the electricity is driven through the contact sheet, allowing the circuit board to connect an electrical signal and initiating a command.

The 8121SD2AGE Pushbutton Switch also incorporates a failsafe mechanism that disconnects the electricity supply once the user releases the pushbutton surface sheet, preventing accidental activation. The contact sheet is also mechanically resilient and highly durable, as it is made of stainless steel and other quality materials tested under extreme circumstances.

Due to its long-lasting and reliable design, the 8121SD2AGE Pushbutton Switch is widely used in a variety of different markets, from the harsh aerospace and military environment to the simpler home appliances market.

Conclusion

The 8121SD2AGE Pushbutton Switch is a reliable and highly resilient quality switch, found in far-reaching industries from the home appliances all the way to the aerospace and military markets. Its application fields are a result of its failsafe design and its contact sheet, which is composed of three layers to ensure both electrical insulation and robustness in all operating conditions.
