Embodiment
The technical solution of the utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Fig. 1~8, a kind of contact system of change-over switch, including moving contact part 3, be fixedly installed on conversion and open
The first static contact 5 and the second static contact 6 on shell 1 outside the Pass；The distance between first and second static contact is set as required, met
Use requirement；
Moving contact part 3 includes moving contact part shell 301, two U-shaped extension springs 302 and moving contact body 303；It is U-shaped to draw
302 points of spring is three sections；First and third section symmetrical, two sections vertical with second segment, and second segment is shaped as straight line, and first and third section is
Vertical pulling spring；The middle part of moving contact body 303 stretches out for long circular, both sides forms two contacts respectively；The side of two contacts
Face is provided with dynamic silver point 307, when moving contact body 303 turns clockwise, on a dynamic static contact 5 of silver point 307 and first
The the first quiet silver point contact set, main power source conducting；When moving contact 303 rotate counterclockwise of body, another dynamic silver point 307 and
The the second quiet silver point 601 set on two static contacts 6 is contacted, stand-by power source conducting；In addition, the oval annulus of moving contact body 303
Position is also connected by soft litzendraht wire 8 with the face terminals 7 being fixed on shell 1；
Two contacts of moving contact body 303 are each formed with groove 305 with oval ring-type position transition position；
The center of moving contact part shell 301 is provided with the square hole matched with the square main shaft 2 of change-over switch, moving contact part
The interior edge of shell 301 matches with the oval annular profile of moving contact body 303, and moving contact body 303 is stuck in moving contact part
The inner side of shell 301；It is provided with a pair of pins 304 on moving contact part shell 301, two U-shaped extension springs 302 pass through 304 points of pin
It is not fixed on moving contact part shell 301, the middle part of two U-shaped extension springs 302 is stuck in the groove 305 on moving contact body 303
Place；
The inner side of moving contact part shell 301 is symmetrically fixed with the first locating part 308 and the second locating part 306；First limit
Position part 308 is arranged on moving contact body 303 and sets the dynamic side of silver point 307, and the side with the moving contact body 303 is tangent；For
The quiet silver point 601 of silver point 307 and second is set to be produced after contacting when moving contact part shell 301 drives moving contact body 303 to rotate
