Micro Limit Switch Classification and application micro switch

Classification and application of micro limit switch

There are many types of micro-switches, and there are hundreds of internal structures. They are divided into ordinary type, small size and ultra-small according to the volume. According to the protective performance, there are waterproof type, dustproof type and explosion-proof type. Single type, double type, multiple type.

There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch open); according to the breaking capacity, there are common type, DC type, micro current type, large current type.

According to the use environment, there are common type, high temperature resistant type (250 ° C), super high temperature resistant ceramic type (400 ° C)

The micro switch is generally based on the non-auxiliary pressing attachment, and is derived from a small stroke type and a large stroke type. Different auxiliary pressing accessories can be added as needed. According to different pressing accessories, the button can be divided into button type, reed roller type, lever roller type, short moving arm type and long moving arm type.

It is small in size, ultra-small, super small and so on. Functionally, it is waterproof. The most common application is the mouse button.

(1) Small micro switch:

The general size is 27.8 wide, 10.3 high and 15.9, and the parameters are high in capacity and low in load.

(2) Ultra-small micro switch

The general size is 19.8 Width, 6.4 Height and 10.2. It has different performances with high precision and long life.

(3) Super small micro switch

The general size is 12.8 inches wide and 5.8 high and 6.5. This type has a very thin design.

(4) Waterproof type

Micro switch application

Micro-switches are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, etc. in automatic switching and safety protection. Military fields such as tanks have been widely used in the above fields, and the switches are small, but they play an irreplaceable role.

At present, the micro-switches on the market in China have different mechanical lifes ranging from 3W to 1000W, generally 10W, 20W, 50W, 100W, 300W, 500W, and 800W. Bronze, tin bronze, stainless steel wire reeds, foreign ALPS can be achieved up to 1000W times, their reeds are made of rare metal titanium.
Can be applied to such as computer mouse, car mouse, automotive electronics, communication equipment, military products, test equipment, gas water heaters, gas stoves, small appliances, microwave ovens, rice cookers, float equipment, medical equipment, building automation, electric Tools and general electrical and radio equipment, 24-hour timers, etc.
