Sealed Micro Switch Feature

Sealing

Our sealed micro switches use advanced sealing technology and meet IP67 protection performance, which is higher than the common IP40, IP65 and other sealing performance. It can effectively prevent water and dust from entering the switch, and it can work stably for more than half an hour even if it is completely immersed in water.

High Temperature Resistance

Excellent temperature resistance is a prerequisite for the stable operation of the switch. Unionwell's sealed micro switches have undergone rigorous temperature resistance tests to ensure stable operation in the range of -40°C~+85°C. They can easily cope with the high temperature working environment of automobile engines and industrial equipment.

Multiple Voltage Specifications

It has multiple rated voltage specifications, such as 250VAC/15A, 125VAC/5A and other rated voltage specifications to choose from, suitable for high-load equipment applications.

Durability

High sealing often leads to high durability. The electrical life of this type of micro switch can reach 100,000 times, the mechanical life can reach 500,000 times, the service life can reach 7 to 8 years, and it has a strict test report.

Multiple Lever Types

Application Of Sealed Micro Switches

The excellent performance of sealed switches makes them widely used in automobiles, home appliances, electronic consumer products, industrial equipment and other fields.

Automotive

Sealed switches are key components of automobile detection systems. For example, G3 ultra-small micro switches and G9sealed mini micro switches are often used in automobile door lock systems to achieve position detection functions. Another example is the G19 waterproof sealed seat switch used in automobile adjustment systems to provide passengers with more precise seat adjustment functions.

Household Appliances

There are also many sealed switches hidden in household appliances, such as the G5W11 waterproof and dustproof micro switch, which is mostly used in ice makers, sweeping robots and other systems. It provides steering control detection in sweeping robots. Another example is the SWD refrigerator door switch, which is more common and is located inside the refrigerator. When the refrigerator door is closed, the switch is pressed to disconnect the circuit and turn off the refrigerator light. In addition, there are more common types of door micro switches, such as Whirlpool microwave door switches.

Consumer Electronics

The small size of sealed micro switches allows them to be installed in small devices such as mobile phones, walkie-talkies and toys. G9A waterproof miniature micro switches and G10 subminiature are often used in walkie-talkie control systems. Another common example is the keyboard switch we use every day, which is actually a type of micro switch. Unionwell has recently launched a new Tesla magnetic axis keyboard switch, which is a testimony to our technological innovation.

Industrial Equipment

Industrial equipment is often in a harsh working environment with heavy humidity, so the application of sealed switches is essential. The G11 DPDT dustproof limit switch is an ideal choice for industrial equipment control switches. Another example is the G12 basic limit switch, which some customers have integrated into the control operating system of a tower crane. Each operating lever uses 4 of these roller-type limit switches, corresponding to the four directions of front, back, left, and right.

FAQ

What is a sealed switch?

A sealed switch is an electrical device enclosed within a protective casing, shielding its internal components from environmental factors such as dust, moisture, and debris. This casing creates a barrier that prevents contaminants from entering the switch mechanism, ensuring its reliability and longevity. Sealed switches are commonly used in various industries and applications where exposure to harsh conditions is prevalent, such as automotive, industrial, and outdoor settings.

What wires are usually used for Unionwell sealed switch G303?

The most commonly used wire gauge is UL1007.

What operating forces can the G5W11 sealed switch have?

The main operating forces of the G5W11 sealed switch are 15 grams, 25 grams, 50 grams, 100 grams and 200 grams, of which 15 grams and 25 grams are only suitable for small currents of 0.1A.

Why is the maximum current of our G9 series sealed switch 6A IP67, while our G91 series can reach 10A IP40? Can the G9 current reach 10A IP67?

G91 Is not sealed, but can reach 10A. G9 miniature micro switch is sealed, but the heat of the current cannot be dissipated, so it is difficult to reach 10A.

What is the main purpose of the G11 sealed switch?

The G11 sealed switch is mainly used on electric valves with explosion-proof requirements.

What are the main applications of the G16 series sealed micro switches?

The G16 sealed micro switches are mainly used in car door locks.
