What is a ball switch

         In simple terms, just like turning on or turning off a light, the switch touches the metal plate inside and the light turns on, and it turns off when it leaves. The ball switch also uses a similar principle. Using the rolling of the beads in the switch to make contact with the metal terminal or change the route of light travel, the effect of conduction or non-conduction can be produced.

         There are currently many different types of ball switches, including angle sensors, vibration sensors, centrifugal force sensors, and photoelectric ball switches. In the past, this type of switch was dominated by mercury switches, and mercury (mercury) was used as the element to touch. However, since the governments of various countries have gradually banned mercury, the touch element has been replaced by a ball.

        The ball switch has a wide range of applications, such as: tire pressure monitoring system (TPMS), bicycle lights, digital photo frame rotation, screen rotation, video lens flip, anti-theft system, etc. The ball switch is suitable for rotating occasions.
