The working principle of the vibration switch
A vibration switch is a switching device capable of sensing and responding to vibration or vibration. Its working principle is based on the internal mechanical structure, when a certain vibration or impact force is applied from the outside, these structures or components will be deformed, which triggers the switch to close or break. Common types of vibration switches include ball type, spring type, piezoelectric type, etc. Each type has its specific application scenarios and advantages and disadvantages.
The ball type vibration switch usually contains one or more freely rolling metal balls, when the external vibration reaches a certain strength, the metal ball will roll and impact the contact of the switch, thereby changing the connection state of the circuit. The spring type vibration switch uses the elastic deformation of the spring to sense the vibration. When the vibration reaches a certain amplitude, the spring will deform and trigger the switch. The piezoelectric vibration switch uses the piezoelectric effect of piezoelectric materials to convert the vibration into electrical energy, and then controls the state of the switch.
