Several types of lightly touching switches need to be introduced to you, of which the most commonly used are usually on and off. Here we give you a detailed introduction.
The function of light touch switch can be divided into two types: one is normally open and the other is normally closed. The most common type is the normal open type, which means that the line is generally disconnected, and the touch of the bullet plate and the base is pulled by pressing the button handle lightly. At this time, the switch is considered to be on, and the button handle shrapnel and the gun point are separated. At this time, the switch is considered to be separated, and the function of the product is OK. When the line is disconnected, the resistance value of the two circuits is 30m ohm. When the switch is on, the touch resistance of the two circuits is 0. At this time, the switch function is very good. Normally closed type is relatively rare, because this is not in line with the usual product design, normally closed type is to correct the switch is on under normal circumstances, when the switch is pulled, the circuit and function are disconnected. The resistance of this switch is contrary to that of normal opening, so it is generally not recommended.
Whether normally open or normally closed light touch switches must be composed of more than two pins, so as to constitute a set of switch functions, normally two feet, four feet, five feet. Why are there five foot switches? Because fifth feet are used for grounding. Of course, there are three feet, generally three feet are more lateral pressure, this third foot is for fixed planning, so we can rest assured that the use of force to press is no problem.
