Metal button switch is widely used and used. What is the structure of metal button switch? Today we will introduce to you.
Metal button switches are also widely used in the electronic switching industry, second only to light touch switches, in some large machine tools or daily elevators and other mechanical and electrical appliances will be more used. Because of the corrosion resistance of the metal button switch, the dustproof and waterproof effect is very good, and the metal key cap, as well as the internal structure of the switch lead to its long service life. So in everyday life we can only know about it in the switching of electrical appliances, but do we have an understanding of its internal structure? How do we know how metal button switches restrict current welding on PCB? Next, let the macro electronic switch factory detail the metal button switch structure to you.
Metal button switch with lamp lock button switch has a metal sheet inside the switch, the middle spring fulcrum, spring displacement and plastic support aging deformation, the switch is not flexible, can be removed after power failure to see, if not plastic damage, may be restored. The zero line inside the switch is straight, and the switch components have nothing to do with it, so because the switch air-jump switch, is through the zero line of the switch insulation layer damage, you can cut off the damaged section of the re-wiring, pay attention to insulation to ensure. It may be that the foot of the indicator lamp is short circuited, and the connection can be reconnected.
Characteristic of wave switch: wave switch is also called ship switch, which has the characteristics of large on-off capacity, reliable performance and safe use. Some switches also have indicator lights, which are very convenient to use. It is mainly used for conversion of power circuit and working circuit state.
Metal button switch features: button switch has self-locking and non-self-locking, self-locking button switch press, then turn on or break the self-locking. Then press it and reset it to the initial state. Metal button switch is easy to install, reliable performance, suitable for a variety of instrumentation and electronic equipment in the role of on-off power supply and conversion circuit.
