Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a small-angle swing-piece switch structure. Background Art

[0002] In a traditional pendulum switch, when the button is pressed and turned, the toggle block is pressed to cause the toggle block to rotate. When the toggle block rotates, the pendulum is driven to rotate, thereby achieving contact or separation between the silver contacts of the pendulum and the silver contacts of the outlet terminal, thereby realizing the on and off of the pendulum switch. However, due to errors caused by the manufacturing and installation processes, the silver contacts of the pendulum and the silver contacts of the outlet terminal cannot contact reliably, which may cause the switch to fail. In addition, the low sensitivity of the pendulum may also cause the switch to fail.

[0003] Therefore, further improvements are necessary. Utility Model Content
