Detailed description of the invention
Referring to figs. 1 through Fig. 3, this utility model knife switch embodiment is described further.
A kind of knife switch, including base 1, protective cover, inlet wire assembly 4, contact knife assembly 5 with go out line component 6, described inlet wire
Assembly 4, contact knife assembly 5 and go out line component 6 and be sequentially arranged on base 1, described protective cover includes contact knife cover 3 and mounting cup 2, described
Contact knife cover 3 covers at out on line component 6 and contact knife assembly 5, and described mounting cup 2 covers on inlet wire assembly 4；Described contact knife cover 3
The one end being mounted opposite cover 2 is provided with clamping step 31, and described mounting cup 2 is provided with the positioning step for docking with clamping step 31
21, the other end of the described relative contact knife cover 3 of mounting cup 2 is provided with elastic clamping hook 22, described base 1 be provided with for elastic clamping hook 22
The draw-in groove 11 of clamping；Described contact knife cover 3 offers placed channel 7, offers screwed hole, described screw thread in described placed channel 7
