As a kind of micro tilt sensing switch, ball switch plays an important role in various electronic products. It uses conductive beads to roll under the action of gravity, touching both ends of the circuit, so as to achieve the circuit on and off. The ball switch not only has a small structure, light weight, but also has significant advantages such as power saving, single function and stability. In the design of the intelligent remote control, the application of the ball switch is mainly reflected in the induction Angle change, the realization of automatic control and so on, especially for the wake up function of the intelligent remote control. When selecting, multiple factors need to be considered comprehensively to ensure that the ball switch can meet the specific application needs.
1. Working principle and type
The ball switch works based on the rolling of conductive beads inside the tube. When an external force (such as tilt, vibration) acts on the switch, the conductive bead will roll to the contact point, thus conducting the electrical circuit. According to the different application scenarios, the ball switch can be divided into many types, such as single bead switch, double bead switch, multi-angle induction switch and so on. Single-bead switches are often used for simple tilt sensing, while double-bead switches provide a more stable trigger signal for applications that require higher precision and reliability. The multi-angle induction switch can sense the tilt in different directions, which is suitable for more complex control needs.
