Type analysis of light touch switch

 

 

There are many kinds of light touch switches, such as equilateral standard type, ultra-thin patch type, sealed in-line type, ultra long life flat type, etc. Electronic sorting out some commonly used types of touch switches, hoping to help you.

 

1、 Equilateral standard

 

The surface shape is square, and the actuator is the standard type on the top surface, so it is an equilateral standard touch switch. There are many kinds of such light touch switches, such as 6.0 * 6.0, 12.0 * 12.0, 6.2 * 6.2, 5.2 * 5.2, 4.9 * 4.9, 7.2 * 7.2, etc. in addition, they have SMD and dip. It is suitable for a variety of operation panels and has a wide range of applications.

 

2、 Ultra thin patch type

 

Its pin is patch type and its height is only 0.8mm, so it is an ultra-thin patch type light touch switch. Its ultra-thin characteristics determine that it is suitable for high-density installation.

 

3、 Sealed in-line

 

Sealed structure is adopted, and the pin is in-line, so it is a sealed in-line light touch switch. It has strong dustproof and waterproof ability and is widely used in home appliances such as air conditioners and washing machines.

 

4、 Super long life flat

 

The service life is up to 1 million times. The actuator is standard flat type, so it is an ultra long service life flat touch switch. Its contacts are made of stainless steel silver plated material, which reduces the connection resistance and greatly enhances the conduction reliability. It is applicable to the operation panel of processing machine tools and household appliances of industrial machinery.

 

5、 Short stroke patch type

 

The stroke of the actuator is only. 15 + / -. 05mm, and the pin is patch type, so it is a short stroke patch type light touch switch. Its short stroke also determines its high service life of 200000 times. It is widely used in vehicle equipment, such as automobile anti-theft remote controller and so on.

 

6、 LED high insulation resistance type

 

The circuit has led, and its insulation resistance is greater than 1000m Ω, so it is led high insulation resistance light touch switch. It is widely used in digital video and audio.

 

7、 Transverse operation type in-line plug-in

 

The actuator is on the side and the pin is in-line, so it is a lateral operation in-line touch switch. Four pins, two of which are fixed and grounded, and the other two are contact on-off terminals. It is widely used in communication equipment.

 

8、 Double acting key SPDT type

 

There is a double actuator, and the contact is SPDT, so it is a double action key SPDT light touch switch. Its insulation resistance is up to 1000m Ω and is widely used in on-board equipment.
