When the pressure is removed, the switch is turned off. Its internal structure is realized by the force change of the metal shrapnel. On and off. The tact switch is composed of an insert, a base, a shrapnel, a button, and a cover. Among them, a waterproof tact switch adds a layer of polyimide film on the shrapnel. The tact switch has plug-in tact switch, patch tact switch, dustproof and waterproof tact switch, small turtle tact switch (side type, vertical type) medium turtle type tact switch (side type, vertical type) ) and many other forms. There are three packages for tact switches: bulk artificial plug-in, SMT patch package, and DIP plug-in taping package. Tact switches are loved by many industries in the market because of their small overall size, small contact resistance, crisp feel when pressed, complete specifications and sizes, and various types. Widely used in: 3C products, automobile industry, information industry,Waterproof Light Switch home appliances, medical equipment, building monitoring systems, smart phones and other industries. The solution to the failure of the boat-shaped switch: There is a metal sheet inside the boat-shaped switch, and there is a spring fulcrum in the middle. The spring displacement and the aging deformation of the plastic bracket will cause the switch to be inflexible. You can take it apart after the power is turned off. Maybe it can be restored. The neutral line inside the switch is straight through, and has nothing to do with the switch components. Therefore, if the switch trips the air switch, the insulation layer of the neutral line passing through the switch is damaged. You can cut off the damaged section and re-wire it. Pay attention to the insulation. . It may also be that the pin of the indicator light is short-circuited, just re-wire it.
