Spring contact pins are an important component used in electronic devices and equipment. These pins are used to establish a reliable and secure electrical connection between a printed circuit board (PCB) and a mating connector. They are made up of two parts: the plunger and the spring.
The plunger is a pointed metal rod that moves up and down, while the spring provides the necessary force to keep the plunger in contact with the mating connector. In this article, we will take a closer look at spring contact pins and their importance in the electronics industry, with a focus on the Promax brand from Dongguan.
The Importance of Spring Contact Pins
Spring contact pins play a crucial role in ensuring the proper functioning of electronic devices. They provide a reliable and stable connection between the PCB and the mating connector, even under extreme conditions such as temperature changes, shock, and vibration. Without a secure connection, the device may fail to operate or may experience intermittent failures, resulting in a loss of functionality and potential damage to the device.
Different Types of Spring Contact Pins
There are several types of spring contact pins available in the market, each designed to meet specific requirements of different applications. Some of the common types of spring contact pins are as follows:
Pogo Pins: Pogo pins are spring-loaded pins that are typically used in applications where a temporary connection is required, such as in test and measurement equipment.
Barrel or Bullet Pins: Barrel or bullet pins are used in applications where a permanent connection is required. These pins are soldered onto the PCB and provide a reliable and secure connection.
Swivel Pins: Swivel pins are designed to provide a stable connection even when the mating connector is misaligned. They are often used in applications where the connector may be subjected to vibration or movement.
Dual-Ended Pins: Dual-ended pins are used in applications where a connection is required on both sides of the PCB. These pins are designed with two plungers and two springs to provide a stable and reliable connection.

Tips for Choosing the Right Spring Contact Pins
When it comes to choosing the right spring contact pins, there are several factors to consider, including the following:
Application Requirements: Different applications require different types of spring contact pins. It is important to consider the application requirements such as the level of vibration, temperature, and shock resistance when selecting the right spring contact pins.
Material Quality: Spring contact pins are made using a variety of materials, including brass, stainless steel, and beryllium copper. It is important to choose high-quality materials that can withstand the rigors of the application.
Plunger and Spring Force: The plunger and spring force determine the level of force required to establish and maintain a reliable connection. It is important to choose spring contact pins with the appropriate plunger and spring force to ensure a stable and secure connection.
Durability: Spring contact pins are subject to wear and tear over time, which can lead to a loss of functionality. It is important to choose spring contact pins that are durable and can withstand repeated use without compromising their performance.
By considering these factors, you can choose the right spring contact pins for your application and ensure that your electronic devices operate reliably and efficiently.
