1. Before installing the tact switch, please confirm in advance whether the switch load of the selected specification is required to be used. Usually, the welding method of each switch with different specifications will be different. The way is also different, for example, the pins are divided into plug-in type and patch type. Once the selected switch does not meet the use, it can not be used by installing the touch switch.
2. Secondly, for the case where the key cap of the light touch switch falls off, the cap of the general switch is fixed by the four rivet points on the base, but as long as the four rivet points are loose, or the rivet point of the switch is welded After the high temperature shrinks, it will cause deformation and will cause the cover to fall off. Therefore, in the selection of the switch, we must pay attention to the material selection of the switch. First, the base of the switch must be made of high temperature resistant material, and the mounting riveting point of the switch must be fixed, so that the switch cover can be solved. The problem.
3. Regarding the waterproofing of the tact switch, the current general waterproof rating of the switch is IP6, but it is not guaranteed to be 100% waterproof. Therefore, please do not let water vapor contact or wet hands on the switch button. Push-button switch to avoid accidents such as short circuit caused by water vapor intruding into the switch, and in serious cases, there may be some electric shock hazards.
4. For the key operation of the light touch switch, the operating force of the switch should not be too large, otherwise the excessive load and weight may cause the deformation of the switch's internal panel spring, which may cause some bad induction actions. In particular, if excessive load is applied to the lateral pressure type of some switches, the riveted part of the switch will be damaged, so that the rear will also cause other hidden troubles.
5. In the normal use of the switch, there are often some situations where the switch button does not respond or is invalid when pressed. The cause of this general problem may be the excessive accumulation of dust and debris in the components inside the switch. As for the conduction that affects the line, it will be caused by the unresponsive phenomenon of these switch buttons. Therefore, after using the switch for a period of time, the internal cleaning work of the switch must be performed regularly to ensure that the switch can operate safely.
In addition, there are still many problems in the operation of the touch switch. Due to the time relationship, I will not mention them one by one. In general, as long as you have a basic knowledge of the switch, you can Avoid failures that reduce the hidden dangers of some switches. Otherwise, some minor operations will be improper, and will also cause post-causal failures.
