Article introduction

Tact switches are frequently used in daily life and work, because the specifications of tact switches are diverse and the applications are also different. If you do not understand the basic knowledge of the touch switch, it is easy to cause the switch to malfunction during use, and it will cause the entire device circuit to fail to work normally. In response to this situation, the manufacturer of tact switches, Gangyuan Electronics, summarized the details of the use of tact switches in daily life.

Precautions during installation

When the welded joint of the switch is not completely cooled, do not lightly touch or shake the contact position, otherwise the switch may loosen. Deformation phenomenon When using a welding switch, do not use high-concentration water-soluble flux, otherwise, when the temperature is too high, the oxidized material of the water-soluble flux will corrode the switch.
The standard waterproof rating is IP6.7. However, the larger the double-digit number after the IP, the stronger the waterproof capability, but it is more expensive than the price. Therefore, when purchasing a switch in general, please use the switch to purchase the corresponding waterproof level according to the requirements of the actual application scenario.

Push switch requirements

Do not press the switch frequently to avoid failure of circuit breaker detection circuit components, which may cause some switch buttons to malfunction. In addition, every time the button switch is activated, a certain amount of current is activated, so often deselecting the switch will also cause unnecessary energy consumption.

Precautions for switch cover

Do not scratch the switch cover on the switch installation cable, otherwise the exposed part of the iron core will easily penetrate some water and gas, which will easily cause line leakage or short circuit. As long as the switch is touched, it will cause a dangerous electric shock accident.

Switching current load regulations

When using a touch switch, you should pay attention to whether the switch current load meets the equipment requirements, because the current load capacity of switches of different specifications is quite different. If the working voltage and working current of some electrical appliances do not match the selected switching power supply, it is easy to cause circuit overload. When the working temperature is too high, the working current will burn directly.

Summarize

The touch switch is a switch that requires manual operation of the button. To operate the switch, you only need to press the switch button to force the internal metal shrapnel to jump to perform the switch function, so the switch must be replaced each time. The button strength is not enough to hold the button with too much strength, otherwise the button strength will damage the induction shrapnel of the touch switch.
