Touch the switch tact switch lightly, press the switch button lightly to make the switch turn on. When the switch is released, the switch will be disconnected. The internal structure of the switch is realized by the force and elasticity of the metal shrapnel. For example, IKI Series Touch Switch.
Because of its small size and light weight, light touch switch has been widely used in electrical appliances, such as video and audio products, digital products, remote control, communication products, household appliances, security products, toys, computer products, medical equipment, automobile keys and so on.
Specification of touch switch
6x6mm, 12x12mm, 5x5mm, 3x6mm
Light touch switch size
The structure of 2 x 4 series includes: Beibei switch/2 x 4 x 3.5;
3 x 3 series: H = 0.35/0.7/1.5/2.0;
3 x 4 series: small turtle with two feet, four feet, medium turtle with four feet, big turtle;
3 x 6 series: structure: 3 x 6 x 2.5 red head and white head;
3 x 6 x 4.3 and 3 x 6 x 5 pins, patches, brackets and side pressing;
4.5 X 4.5 Series: H = 3.8/4.3/5/6/7/8.
5.2 x 5.2 series: structure: 0.8h without cover, flat cover, 1.5, 1.7, 2.5, 4.3h with copper head and plastic head;
6 x 6 series: H = 2.5/2.7/3.1/3.4/3.8/4.3/4.5/4.8/5.5/6.5/7/8/9/12.
Packaging Types of Touch Switches
1. SMT patch;
2. DIP plug-in.
Main Technical Parameters of Touch Switch
1. Environmental protection standards include RoHS, halogen-free and EU limits on the control value of hazardous substances.
2. Rated current and voltage; usually milliampere, 50mA 12VDC.
3. Operation strength: 50 gf, 100 gf, 160 gf, 260 gf, 320 gf, 520 gf.
4. Operating life; Operating life is generally inversely proportional to operating force. Take 160gf as an example, 6 X6 switch can achieve 1 million to 3 million times of service life.
5. Working environment temperature; - 25 degrees Celsius to + 70 degrees Celsius
6. Switching stroke.
Rated voltage
It refers to the safe voltage allowed by the switch in normal operation. If the voltage at both ends of the switch is greater than this value, the ignition breakdown between the two contacts will occur.
Rated current
The maximum safe current allowed to pass when the switch is switched on. When this value is exceeded, the contact of the switch will burn out due to excessive current.
insulation resistance
The resistance value of the conductor part and the insulation part of the switch should be above 100M.
contact resistance
When the switch is on, the resistance between each pair of contacts is generally required to be below 0.1-0.5_. The smaller the value, the better.
Withstand voltage
The lowest voltage that a switch can withstand between conductor and ground.
Life
It refers to the number of times that the switch can be operated under normal working conditions, which generally requires about 5000-35000 times.
