Two types of light touch switch are introduced. What specifications and details are there? Let's give you a detailed introduction.
Two types of light touch switch are introduced to you, usually according to different specifications to appear different types:
The function of touch switch can be divided into two types: one is normally open type and the other is normally closed type. The most common type is the normal open type, which means that the line is generally disconnected, and the button handle is pressed to touch the shotpoint contact between the shrapnel and the base. At this time, the switch is considered to be on, and the shrapnel and the shotpoint are separated when the button handle is released. At this time, the switch is regarded as separate, and the performance of the product is OK. When the line is disconnected, the resistance of the two circuits is 30m ohm, and when the switch is on, the contact resistance of the two circuits is 0, so the performance of the switch is very good. Normally closed type is relatively rare, because it is not in line with the conventional product design. Normally closed type refers to the switch is on, when the switch is activated, the circuit and function are disconnected. The resistance value of this kind of switch is the opposite of that of normal switching, so it is generally not recommended to use.
Whether it is open or closed, the touch switch must be composed of more than two pins, so as to form a group of switch functions, normally two feet, four feet and five feet.
Why are there five-legged switches?
Because the fifth foot is for grounding, I think you all know what the grounding foot is for. Of course, there are three feet, generally the three feet are more lateral pressure, this third foot is designed for fixed, so you can rest assured that use, hard to press is no problem.
