The toggle switch is used to turn the circuit on or off by flipping the switch handle to achieve the purpose of switching the circuit. Many people have seen the appearance, shape and pin form of the toggle switch, but the internal structure of the toggle switch is rarely seen because no one has ever dismantled it. The toggle switch has one gear, two gears, three gears, four gears, five gears, six gears, seven gears, eight gears; there are single row, double row, three row and so on. Whether it is a horizontal handle, a straight handle, or a miniature, its internal structure is similar. The iron shell toggle is divided into three forms: rubber, wave beads, and shrapnel. Among them, the shrapnel toggle has the highest lifespan, the best hand feeling, and the highest unit price; the cheap, simple and easy-to-do is the glue toggle; Compare the mid-range toggles.
Toggle the internal structure and components of the switch! The toggle switch is made of:
1. The shell is nickel-plated iron shell (salt spray 12-24 hours)
2. The rubber handle is made of plastic material (materials are divided into POM, PPA, PBT)
3. The chip is made of phosphor copper and silver (contact resistance can be less than 30 milliohms)
4. The terminal pins are composed of silver-plated brass
5. The bottom plate is composed of PCB board
6. The spring is composed of high-performance springs imported from Japan
7. Dispensing is made of sealed temperature-resistant red glue
8. The wave bead is composed of stainless steel wave column
The inner structure of the micro toggle switch is roughly the same as that of the toggle switch, but the form is different. In addition, it has many unique features. For example, compared with other switches, it has the feature of flexible slider action, which means that its switching speed is very fast, because we know that as a switch If we have pressed the switch, but cannot turn off the power in time due to its inflexible slider action, it may cause some unnecessary troubles. In addition, it has the characteristics of stable performance, which means that it is very stable during use, and there will be no small faults or problems.
