Ball switch description
Simply put, just like turning on or turning off a light, the switch touches the metal plate inside and the light turns on, and when it leaves it, it turns off. The ball switch uses a similar principle. By making use of the rolling of the beads in the switch, making contact with metal terminals or changing 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 sensor switches, 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was used as the element to touch, but since governments in various countries have banned mercury, the touch element has been replaced by a ball.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 frame rotation, screen rotation, video lens flip, anti-theft system, etc. The ball switch is suitable for rotating occasions.
