The Conduction Of Tactile Switch Button

The tact switch is made by the internal metal shrapnel force to realize the on-off, the distance between the metal sheet and the base bubble point contact is called the trip. The stroke is divided into long stroke, short stroke and medium stroke, and its stroke is determined according to the structure, size and performance requirements of the tactile switch itself. The shortest short stroke limit is 0.8mm, known as the small stroke, generally using ultra-thin. The middle stroke is between 0.13 and 0.3mm, generally used in plug-in type. Long stroke between 3.0-0.5, generally applied to silicone buttons and heavy products. The smaller the stroke, the smaller the button sound, on the contrary, the higher the stroke, the greater the sound, the lower the life. Can be set according to the mechanism of the switch itself, can achieve sound and silent effect. Influencing factors on the product: the length of the trip is the most direct influencing factor is the action force, the action force is usually divided into: light (120g below), heavy (300g above) and standard strength (150-250g), the shorter the stroke of the switch is lighter, its life is higher; On the contrary, the greater the strength of the trip, the higher the life; Middle stroke is the most standard stroke, its life is moderate and very in line with human engineering, so it is widely used.
