Specific embodiment
Technical scheme of the present invention 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, is fixedly installed on conversion and opens
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, is met
Requirement；
Moving contact part 3 includes 301, two U-shaped tension springs 302 of moving contact part shell and moving contact ontology 303；U-shaped drawing
It is three sections that spring 302, which divides,；First and third section symmetrical, and two sections vertical with second segment, and the shape of second segment is straight line, and first and third section is
Vertical pulling spring；303 middle part of moving contact ontology extends outwardly for long circular, both sides and is respectively formed two contacts；The side of two contacts
Face is both provided with dynamic silver point 307, when moving contact ontology 303 rotates clockwise, on dynamic 307 and first static contact 5 of silver point
First quiet silver point contact of setting, main power source conducting；When moving contact ontology 303 rotates counterclockwise, another dynamic silver point 307 and the
The the second quiet silver point 601 set on two static contacts 6 contacts, stand-by power source conducting；In addition, the oval annulus of moving contact ontology 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 ontology 303 are each formed with groove 305 with oval cyclic annular position transition position；
301 center of moving contact part shell is equipped with the square hole to match with the rectangular 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 ontology 303, and moving contact ontology 303 is stuck in moving contact part
301 inside of shell；A pair of of pin 304 is provided on moving contact part shell 301, two U-shaped tension springs 302 are divided by pin 304
It is not fixed on moving contact part shell 301, the middle part of two U-shaped tension springs 302 is stuck in the groove 305 on moving contact ontology 303
Place；
301 inside of moving contact part shell is symmetrically fixed with the first locating part 308 and the second locating part 306；First limit
Position part 308 is arranged on dynamic 307 side of silver point of the setting of moving contact ontology 303, tangent with the side of the moving contact ontology 303；For
307 and second quiet silver point 601 of silver point is made to produce after contacting when moving contact part shell 301 drives moving contact ontology 303 to rotate
Raw contact pressure.First locating part 308 and the second locating part 306 and 303 phase section of contact body are arc surface.
When in use, the square shaft 2 of change-over switch is passed through from the square hole that 301 center of moving contact part shell is equipped with, rotation
Square shaft 2 can drive moving contact part shell 301 to rotate synchronously simultaneously, then moving contact ontology 303 be driven to rotate.Such as Fig. 7 institutes
