Touch the switch tact switch. When in use, press the switch button to turn on the switch. When the hand is released, the switch will turn off. The internal structure of the switch is realized by the force of metal shrapnel. For example, the IKI series of Lingyi touch switch.

 

Due to its small size and light weight, touch switch is widely used in electrical appliances, such as audio-visual products, digital products, remote control, communication products, household appliances, security products, toys, computer products, medical equipment, car buttons, etc.

Package type of touch switch

 

1. SMT patch;

 

2. Dip plug-in.

 

Main technical parameters of touch switch

 

1. Environmental standards, including RoHS, halogen-free, and the European Union and other regions to limit the control value of hazardous substances.

 

2. Rated current and voltage: usually Ma pole, 50mA, 12VDC.

 

3. Operation force: 50gf, 100gf, 160gf, 260gf, 320gf, 520gf.

 

4. Operating life: the operating life is generally inversely proportional to the operating force, for example, 160gf, 6x6 switch can achieve a life of 1 million ~ 3 million times.

 

5. Working environment temperature; - 25 ℃ to + 70 ℃

 

6. Switch travel.

 

Rated voltage

 

It refers to the safety voltage allowed by the switch in normal operation. If the voltage applied to both ends of the switch is greater than this value, it will cause ignition and breakdown between the two contacts.

 

Rated current

 

It refers to the maximum safety current allowed to pass when the switch is on. When this value is exceeded, the contacts of the switch will be burned due to excessive current.

 

insulation resistance

 

It refers to the resistance value of the conductor part and insulation part of the switch, and the insulation resistance value shall be more than 100m Ω.

 

contact resistance

 

It refers to the resistance value between each pair of contacts when the switch is on. It is generally required to be less than 0.1-0.5 Ω. The smaller the value, the better.

 

Withstand voltage

 

It refers to the lowest voltage that the switch can bear between conductor and ground.

 

life

 

It refers to the number of times that the switch can be operated under normal working conditions, generally about 5000-35000 times
