micro switches for sale Micro switches are precision components with compact mechanical structure to accomplish rapid switch in different circuits. To buy the appropriate micro switch for specific applications, there are five aspects we should pay attention to.

Depending on the application positions, we would have different requirements in the dimensions of switch cases. For instance, mini waterproof housing with dimensions around 10mm or even smaller, is mainly used in automotive vehicles, which usually carry signal current and requires switching in limited space. While it comes to home appliances, the situation is different. Basic micro switch housing with dimensions exceeding 15/20 mm would be adopted to endure higher current and harsh environment of extreme heat and cold.

Even for the same switch series, there are different electrical loads up to the application situation. We need to clarify which configuration is the most suitable solution to the end products using micro switches. The rating load of switches should comply with that of the application positions.

Switch performance also relies on the setting of several mechanical parameters-PT, OT, MD, RT, OF, TF, RF, TTP, OP, RP, FP. Among them OP (Operating Position) and OF (Operating Force) are the most important elements deciding whether the switch is suitable to be used in the application position.

All global markets have their compulsory access permit certifications such as UL or cUL for North America, ENEC for Europe, and CQC for China etc. Manufacturers should check whether the switches have been granted neccessary certifications before decision making.

Some custom projects may need special design like gold plated contacts, thermoplastic cases/pin plungers, extraordinary terminals or atuating levers etc. In this case, selecting a trustworthy switch manufacturer with strong R&D and real-time production capability is particularly important. Unionwell is definitely your NO.1 choice!
