In the field of micro switches, based on differences in circuit structure, micro switches are divided into four types: SPST switches, SPDT switches, DPDT switches, and DPST switches. Their applications differ. So what are the differences between these four types of micro switches? This article will explain the differences in detail!

Switches are an indispensable basic component in our modern devices and daily lives. However, switches come in various types and have different applications. For example, while micro switches and regular switches may sound similar, they are actually quite different. This article will explain in detail: What is the difference between a micro switch and a regular switch?

In the field of electronic components, "Switch" and "Micro Switch" are two types of components most often compared together. However, while these two types of switches may seem similar, there are significant differences between them. This article will provide a detailed explanation of "What Is The Difference Between A Switch and A Micro Switch?"

This article will provide a comprehensive analysis of the key technologies and engineering value of sealed micro switches, covering their definition, working principle, type classification, typical applications, and selection guidelines.

Unionwell was named one of Huizhou's Top 10 high-tech SMEs in 2025, highlighting 30 years of innovation, CE/ISO-certified sealed subminiature micro switches and advanced smart manufacturing.

Subminiature micro switches have become an indispensable core component in modern electronics and smart device manufacturing. However, not all subminiature micro switches can meet business needs, making custom subminiature micro switches a top choice for large projects. This article will provide detailed information on custom subminiature micro switches!

Among micro switches, subminiature micro switches are widely used in various fields due to their small size, fast response, and high reliability. They have become an indispensable component in the manufacture of many electronic devices. This article will provide a detailed introduction to subminiature micro switches.

In modern electrical control systems, snap action micro switches are widely used in a variety of applications, from automobiles to industrial equipment to household appliances, thanks to their high precision, fast response, and stable performance. This article will comprehensively introduce the applications of snap action micro switches in various fields!

Unionwell showcased its latest automotive micro switches, waterproof switch solutions, and magnetic keyboard switches at the 2025 Hong Kong Electronics Fair, highlighting innovation and reliability.

While a snap action micro switch is often referred to as a micro switch, it's actually somewhat different. A key feature of the snap action micro switch compared to other switches is its snap-action mechanism, resulting in a fast response. This article provides a comprehensive and detailed introduction to the snap action micro switch.

Therefore, we've compiled this list of sealed switch manufacturers to help you quickly find a reputable, high-quality manufacturer. We hope this helps!

Unionwell announces its 2025 National Day and Mid-Autumn Festival holiday from October 1-7. Plan your orders in advance to ensure smooth delivery.

However, choosing the right switch type for different application requirements is crucial. Among all micro rocker switches, SPST and DPDT are the two most common types. These two types differ significantly in their structural principles, performance characteristics, and application scenarios. This article will explain the differences between the two in detail.

Automotive micro switches play a vital role in modern cars. From door locks and window controls to lights and wipers, they ensure the proper functioning of the vehicle while providing a more convenient driving experience. This document introduces the five most commonly used and applicable micro switches for automotive door applications, helping buyers make the right choice.

Waterproof micro switches are used in many fields, including automobiles, home appliances, and industrial equipment. However, few people pay attention to the reason why waterproof micro switches are waterproof. Because waterproof micro switches are sealed at the factory, it is impossible to remove the outer shell to observe the internal structure. This article will provide you with an in-depth dissection of the waterproof micro switch and explore its internal structure!

Micro switches offer a variety of circuit configurations, with SPDT micro switches being the most widely used. However, requirements for electrical parameters, protection levels, mechanical lifespan, and actuator structure vary significantly across applications. Choosing the right SPDT micro switch for your application presents a challenge for many buyers.

However, despite rigorous design and production testing, automotive micro switches can still experience various failures over time. These failures not only affect vehicle functionality but can also pose safety risks and increase after-sales maintenance costs. This article will analyze common automotive micro switch failure types, explore their root causes, and provide practical preventative measures.
