AI Technical Summary
The contacts of existing changeover switches are prone to loosening when installed in the insulating base because they are only in contact with the base, which can lead to poor contact and affect normal use.
The positioning structure includes a connecting block, a collar, and a cylinder. By rotating the collar on the connecting block, the collar is fitted onto the cylinder, ensuring that the contacts are tightly inserted into the insulating base. Combined with the elastic effect of the spring, a tight connection is achieved.
This ensures tight contact between the changeover switch contacts and the insulating base, preventing loosening and guaranteeing reliability and sealing during normal use.
