Change-over switch

Abstract

The invention discloses a change-over switch. The change-over switch comprises an epoxy glass fiber extrusion rod, a change-over switch supporting structure, a quick mechanism bottom plate, a change-over switch moving arc contact bracket and a static arc contact mounting and fixing mechanism, the change-over switch supporting structure is provided with a change-over switch moving main contact anda rotating support. The epoxy glass fiber extrusion rod is positioned in the change-over switch supporting structure; the quick mechanism bottom plate is formed by integrally flanging and stretching ametal part; the thickness of the rotating support is 9.5 mm; the static arc contact mounting and fixing mechanism comprises a screw-shaped contact, a pressing plate and a locking nut; the screw-shaped contact penetrates through the through holes in the change-over switch moving arc contact bracket and the pressing plate and is in threaded connection with the locking nut, the locking nut is tightly attached to one side of the pressing plate, the change-over switch moving main contact is of a macromolecule integral clamping plate structure, and a flexible connection structure is arranged on thechange-over switch moving main contact. The static arc contact mounting and fixing mechanism is reliable in mounting and positioning.

Description

technical field [0001] The invention relates to the technical field of switch, in particular to a switch. Background technique [0002] The toggle switches on the motherboard are used to control various circuits or components in the system. These switches are called dip switches, and they are usually packaged in a plastic box as a group of two or more. The existing switching switches are unreliable in installation and positioning, have low mechanical strength, short service life, and are not fast enough. Contents of the invention [0003] The purpose of the present invention is to provide a switch to solve the problems raised in the background art above. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a diverter switch, including an epoxy glass fiber extrusion rod, a diverter switch support structure, a quick mechanism bottom plate, a diverter switch dynamic arc contact bracket, and a static arc contact inst...
