Tact switch specifications and dimensions

Touch the switch tact switch. When you use it, press the switch button to turn the switch on. When the hand is released, the switch will be disconnected. The internal structure is forced by the metal spring to achieve the on/off. Such as the IKI series of tact switches.

The tact switch is widely used in electrical appliances due to its small size and light weight, such as: audio and video products, digital products, remote controls, communication products, household appliances, security products, toys, computer products, medical equipment, car buttons, and the like.

Tact switch package type

1. SMT patch;

2, DIP plugin.

Tact switch main technical parameters

1. Environmental protection standards, including RoHS, halogen-free, and EU-related restrictions on the control of hazardous substances.

2, rated current, voltage; usually mA, 50mA 12VDC.

3. Operating strength; 50gf, 100gf, 160gf, 260gf, 320gf, 520gf.

4, operating life; operating life is generally inversely proportional to the operating strength, for 160gf, usually 6x6 switch can achieve 1 million times ~ 3 million life.

5, working environment temperature; -25 degrees Celsius to +70 degrees Celsius

6, switch stroke.

Rated voltage

Refers to the safe voltage allowed by the switch during normal operation. The voltage applied across the switch is greater than this value, which can cause a breakdown between the two contacts.

Rated current

Refers to the maximum safe current allowed to pass when the switch is turned on. When this value is exceeded, the contacts of the switch will burn out due to excessive current.

Insulation resistance

Refers to the resistance value of the conductor part and the insulation part of the switch, and the insulation resistance value should be above 100 MΩ.

Contact resistance

It means that the resistance value between each pair of contacts in the open state of the switch is generally required to be 0.1-0.5Ω or less. The smaller the value, the better.

Withstand voltage

Refers to the lowest voltage that the switch can withstand between the conductor and ground.

life

It refers to the number of times the switch can be operated under normal working conditions, and the general requirement is about 5000-35000 times.
