Now many electrical appliances will enhance the requirements, use thin film touch switch, this kind of touch switch specific specifications and parameters, we also need to know more about it.
The thin film touch switch tact switch, when using the switch button, the switch can be switched on. When the hand is loosed, the switch is broken and its internal structure is connected by the force of the metal projectile. For example, the IKI series film of the game is light touch switch.
Light touch switch is 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, car keys and so on.
Light touch switch specification of thin film
6x6mm, 12X12MM, 5x5mm, 3x6mm
Light touch switch size of thin film
The 2 * 4 series of structures are: switch /2 x 4 x 3.5;
3 x 3 Series: H=0.35/0.7/1.5/2.0;
3 * 4 series: small turtle, two feet, four feet, four legs, big turtle.
3 * 6 Series: the structure has 3 x 6 x 2.5 red head and white head.
3 * 6 x 4.3 and 3 * 6 * 5 pins, patches, brackets, side buttons;
The 4.5 * 4.5 series: H=3.8/4.3/5/6/7/8.
5.2 * 5.2 series: the structure is: no lid 0.8h, flat cover, copper head, plastic head 1.5, 1.7, 2.5, 4.3h;
6 * 6 Series: H=2.5/2.7/3.1/3.4/3.8/4/4.3/4.5/4.8/5/5.5/6/6.5/7/8/9/12.
Type of thin film light touch switch package
1, SMT patch;
2, DIP plug-in.
Main technical parameters of light touch switch of thin film
1, environmental protection standards, RoHS, halogen free, and the EU and other areas of harmful substances control value limits.
2, rated current, voltage; usually Ma Ma, 50mA 12VDC.
3, operation intensity; 50gf, 100gf, 160gf, 260gf, 320gf, 520gf.
4, operation life; operation life is generally inversely proportional to operation intensity; take 160gf, usually 6x6 switch can achieve 1 million ~300 life.
5, working environment temperature; -25 degrees Celsius to +70 degrees Celsius.
6. Switch stroke.
It refers to the safe voltage permitted by the switch when it is working normally. The voltage at the two ends of the switch is greater than this value, causing a breakdown between the two contacts.
The maximum safe current allowed when the switch is connected. When this value is exceeded, the contact of the switch will burn down due to the excessive current.
The resistance value between the conductor part and the insulation part of the switch, and the insulation resistance value should be above 100M ohm.
When the switch is in the open state, the resistance value between each pair of contacts is generally less than 0.1-0.5 ohm. The smaller the value, the better.
The lowest voltage that the switch can withstand between the conductor and the ground.
It refers to the number of switches that can operate under normal working conditions, generally around 5000-35000 times.
