What is a Sealed Micro Switch?
A sealed micro switch is a precision switch with a snap-action mechanism. Its sealed design prevents environmental influences on the internal contacts. Depending on the required protection, sealed micro switches can be further categorized as dustproof and waterproof.
Dustproof sealed switches primarily protect against dust, particulate matter, and fine impurities found in industrial environments. Typically offering IP40 protection, they effectively block particles larger than 1mm or airborne dust from entering the contact area, preventing malfunction or poor contact due to accumulation. They are suitable for applications exposed to dust risks, such as textile machinery, household appliances, and power tools, and are an ideal choice for equipment requiring long life and stable operation.
Waterproof sealed switches offer enhanced liquid protection, often with an IP65 or IP67 rating, and can withstand water jets, humidity, and even brief immersion. Internally, they utilize a sealant or double-layer seal to protect the contacts from moisture corrosion, maintaining highly reliable signal output. Widely used in car door lock systems, outdoor control panels, kitchen appliances and other environments with frequent humidity or water contact, it is a true sealed snap action switch

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.
Application of Sealed Micro Switches
Sealed micro switches are widely used in automotive door locks, industrial limit switches, home appliance safety systems, and medical device controls.
