What is the power of tap switch? We will introduce the specific standards below

Because the touch resistance is less, the standard is diversified, and the precise operation force error is various, it is widely used in electronic equipment and white household appliances,
For example: video and audio products, remote control, communication products, digital products, home appliances, toys, computer products, fitness equipment, medical equipment, security products, etc. Because touch the switch to the environmental conditions (application pressure is less than 2 times of elastic force / environmental temperature and humidity conditions and electrical performance), large equipment and high load buttons are directly replaced by conductive rubber or metal spring of the switch, such as medical equipment, TV remote control, etc.
The tap switch is going to be popularized and miniaturized. It can improve the power of the tap switch and make it miniaturized and lightweight. The limited voltage and current of the switch and connector need to be left with a certain margin. The tap switch is to turn the circuit on or off by pushing the handle of the switch, so as to achieve the purpose of switching the circuit. Common varieties include single pole double position, single pole three position, double pole three position and double pole double position. It is generally applicable to low-voltage circuit, with the characteristics of flexible slider action, reliable and stable performance. It can be divided into small current light touch switch and large current light touch switch according to current. When the power supply of the tap switch is normal, all kinds of EPS power supplies directly supply the power supply for the load through the bypass. The backup ups and Online Interactive UPS in the UPS power supply supply the regulated and purified power supply for the load through the bypass. The online UPS in the UPS power supply always supplies the pure inverter alternating current with the same frequency, phase and small error as the power supply.
Metaldome technical standard table of metal film switch:
No. skill index classification: the key life of testing instrument 1 corresponding to general skill index. Circle 1. Can hit 1 million times;
1. After 1 million times of force and clickratio tests, compared with the initial value, the change rate is less than 30%;. Waist circle
2. The occupation requires 500000 times, and our company will test according to the requirement of 1 million times;
3. After 500000 times of force and clickratio tests, the change rate is less than 30% compared with the initial value; gp-ra-500-3 longevity tester
4. Shrapnel shape: round / waist round / Quadruped / triangle / abnormity/
5.Force/ClickRatio。 Force: 100gf ~ 300gf; (tolerance: ± 20GF). Clickratio: 50 ± 15% (conventional) manual or S205 load curve tester
6. The range of shrapnel is 0.13-0.22mm (different from shrapnel of different standards) and the 5-scale tolerance of S205 load curve tester. Tolerance of incoming shrapnel: + 0, - 0.05mm (Convention) jt-300a projector
