The Difference Between Microswitch And Tact Switch


In recent years, With the Industry production technology updates, the need for micro switches and tact switches increased quickly! It’s so important to learn the difference between tact switches and microswitch!


Tact Switch

Tact switches are ordinary electronic switches, also called vital switches, which belong to mechanical actions. At first, the tact switch appeared in Japan (a sensitive switch). People used it to meet the operating force conditions, then applied pressure to the switch operation direction. 


The Switch Function Is Closed And Connected

When the pressure is removed, the switch is opened. Its internal structure is supported by metal shrapnel. The force changes to achieve on-off. 

The tact switch comprises an insert, base, shrapnel, button, and cover plate. The waterproof tact switch adds a layer of polyimide film to the shrapnel. During use, a light press will connect the circuit, let it go, and then disconnect it.

Tact switches have the advantages of small contact resistance, accurate operating force errors, and diversified specifications. 

They are widely used in electronic equipment and white appliances, such as audio-visual products, digital, remote controls, communication, and household appliances. Electrical appliances, security products, toys, computer products, fitness equipment, medical equipment, currency detector pens, laser pen buttons, etc. Because of the environmental conditions of the light touch switch (the pressure is less than two times the elasticity/ecological temperature and humidity conditions and electrical performance), large equipment and high-load buttons are directly replaced by conductive rubber or metal shrapnel of the pot switch, such as medical equipment, TV remote control, etc.


Tact Switch Classification

Tact switches can be divided into standard type, sealed type, pendulum type, long type, SMD type, waterproof type, semi-circular array type, etc.

The contacts are silver-plated and gold-plated. Its installation methods mainly include plug-in type, surface installation, etc. The sizes are 4.5×4.5mm, 6×3.5mm, 6×6mm, 6.6×6.6mm, 8×8mm, 10×10mm, 12×12mm, and so on.


Micro Switch

microswitch is a fast machine with a small contact interval. It uses a specific stroke and force to achieve the switch action

There is a drive lever switch outside of it. The contact distance of the switch is small, so It is called a micro switch, also known as a sensitive switchSnap Action Switch. A switch can act quickly. Suitable for door switch of anti-theft system, etc.


Micro Switch Classification

There are many types of micro switches, and there are hundreds of internal structures.

They are divided into ordinary, small, and ultra-small according to the volume; 

According to the protection performance, they are divided into waterproof, dustproof, and explosion-proof; 

According to the nature of protection, they are divided into single, double, and multiple types.

Another type of strong cut-off microswitch (when the reed is not working, the external force can also make the switch open); 

The breaking capacity can be divided into ordinary, direct current, microcurrent, and large current.

According to the use environment, it is divided into ordinary type, high-temperature resistant type (250℃), super high temperature resistant ceramic type (400℃)


Generally, micro switches without auxiliary pressing devices are typically used as the primary type, and small and large strokes are derived. Different extra pressing accessories can be added according to the needs. The additional pressure can be divided into button type, reed roller type, lever rolling type, short boom type, long boom type, and other forms.

The size is small, super small, and so on.
