Pushbutton switches are used in a variety of electronic circuits, from simple control buttons to complex automation systems. Push-type switches are commonly used in home and industrial control systems, and the 37FBR1-AAP4121N can be found in many applications when such switches are needed. The capabilities and features of this switch are described and discussed here, followed by a discussion of its working principle.

Application Fields

The 37FBR1-AAP4121N is an integrated push-type switch that is widely used in various electrical and electronic products. It is a single pole, single throw (SPST) momentary switch used to control power on/off, audio and video products, toys, home appliances, and the like. This type of switch is also widely used in industrial control systems, including relays, motors, solenoids, or other devices that need momentary ON/OFF control.

Moreover, its size is as small as 6.2mm or 8.7mm, making it a versatile choice for low profile applications where its small size limits the amount of space available. It is widely accepted by associated products requiring lower contact resistance, higher insulation resistance and more secure fastening structure.

Features

This integrated switch has several advantages compared to other common types of push switches. It is hermetically sealed, that is, the interior and exterior of the switch are completely separate, which greatly enhances its corrosion resistance, dust-proof and waterproof performance, and greatly improves the service life of the switch. In addition, it has excellent anti-vibration and anti-shock properties. Compared to other push-type switches, it has a much lower contact resistance, that is, its contact resistance is 0.2Ω even when the contact is closed, and the insulation resistance is above 5MΩ, which ensures reliable and long-lasting performance.

The contact material is printed with gold plated tin, which is extremely durable and highly reliable, and can be used in harsh environments. The lead wire tail adopts a reinforced structure with an integrated seam waterproof cover, which makes the wiring process much more reliable and secure. In addition, its mechanical life is more than several hundred thousand times, without any problems even after a long period of continuous operation.

Working Principle

The 37FBR1-AAP4121N is an SPST momentary push-type switch, and its working principle is relatively simple. When the user presses and releases the switch, the switch contact goes from open to closed, or from closed to open, to generate a control signal. That is, the switch contact is closed when the user presses the switch, and open when the user releases the switch.

When the switch is pressed, the slider at the front end body will be actuated and drive the contact to achieve electrical connection, and the lead wire form the switch forms a closed circuit. When the switch is released and the switch returns to its original position due to the force generated by the springs, the contact also returns to its original position and breaks the circuit.

Conclusion

The 37FBR1-AAP4121N integrated push-type switch is a popular choice for many electronic products, from home and industrial control systems to toys and appliances. Its small size and miniaturized structure make it ideal for low profile applications, while its excellent anti-vibration, anti-shock, and corrosion resistance ensures reliable and long-lasting performance. Its simple working principle allows it to generate control signals with just a press or a release.
