In modern cars, the door lock switch is a tiny component, but it carries multiple functions such as control, safety, and feedback. It not only determines whether the user can smoothly complete the door opening and closing operations, but also affects the normal operation of the vehicle anti-theft system and smart entry system.

The 4th CPSE 2025 will be held at the Shanghai Automobile Exhibition Center from May 14 to 16, 2025. Unionwell will bring a variety of new energy micro switch products to the grand debut, and sincerely invite you to visit our booth (S09-21).

If you have learned about micro switches, you will know that there are four types of switch circuits: SPST, SPDT, DPST and DPDT. Perhaps you have more or less learned about the previous switches, but today we will discuss in detail the most complex DPDT circuit switch. What is a DPDT switch?

Those who are familiar with micro switches know that micro switches can be divided into four circuit modes: SPST, SPDT, DPST, and DPDT. The most widely used are SPST, SPDT, and DPDT. Let's continue with the previous article "What's the difference between SPST and SPDT switches?" and continue to explore What's the difference between SPST, SPDT and DPDT?

In industrial automation, electrical equipment manufacturing and precision control systems, the selection of micro switches is crucial. SPST and SPDT micro switches are two common switch types and are often used in different control logic scenarios. So what is the difference between SPST micro switches and SPDT micro switches? What application scenarios are they suitable for? Which switch better meets project requirements?

In the automation, electrical control and automotive industries, micro switches are an indispensable core component. A careful observation will reveal that most micro switches use the SPDT circuit mode. So how to use the SPDT micro switch correctly? Today, this article will explain this issue to you from a professional perspective!

Those who are familiar with micro switches know that there are four types of micro switches: SPST, DPST, DPDT and SPDT. Among them, SPDT (Single Pole Double Throw) micro switches have become one of the most widely used types due to their flexible circuit switc...

Unionwell is excited to announce our participation in the upcoming electronica China 2025, one of the most influential exhibitions for the electronics industry in Asia. We warmly welcome all partners, customers, and industry professionals to visit our booth and experience our innovative switch solutions in person.

This article will introduce the wiring method of micro switch in detail to ensure that you can complete the connection correctly and safely.

Microwave ovens are common household appliances in our daily lives, but over time, some minor problems may occur, such as when the Frigidaire microwave oven fails to start, stops running, or the door is not completely closed but still operates. Don't rush to replace it, maybe it's just the micro switch on the microwave door that is broken. So how should we detect if the microwave door switch is faulty?

In fact, this is a professional name for circuit switches in the electronics industry. Currently, there are four types of micro switches: SPST (single pole single throw), SPDT (single pole double throw), DPST (double pole single throw), and DPDT (double pole double throw). This article mainly talks about the more common SPDT switches and DPDT switches, so that you can better understand their differences and advantages and disadvantages.

 

The micro switch is responsible for controlling the conversion of electrical signals, and the conversion of electrical signals is related to the circuit mode. There are four circuit modes of micro switches: SPST, SPDT, DPST and DPDT. Among them, the most used is the SPDT circuit micro switch. So why is SPDT the most used micro switch circuit? What is the difference with other circuit modes? This article will give you a detailed answer!

In the control system of a golf cart, micro switches play a vital role, for example in the operation of the accelerator pedal. The control of the accelerator pedal and the monitoring of the brake system both rely on the precise control of the micro switch. So how does the micro switch work in a golf cart?
