Utility model content
The utility model provides the circuit changing switch that a kind of closure is good, skew does not occur Compress Spring for above-mentioned technical problem.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of circuit changing switch, comprise turn-button, rotating shaft and casket body, described rotating shaft one end connects turn-button, the other end runs through casket body, described casket body comprises top base, bottom base and multiple segmented disc, described segmented disc includes segmented disc base and segmented disc wall, on described segmented disc base, be provided with touch device, described touch device comprises movable contact body, be arranged on the movable contact spring in movable contact body and press the Compress Spring of movable contact spring, and the detent mechanism of fixing Compress Spring.
The utility model is further set to: described Compress Spring detent mechanism is that segmented disc wall cross section is rendered as trapezoidal detent.
By adopting technique scheme, cross section is trapezoidal groove, can be by stable spring one end being arranged on segmented disc wall, and spring can be shifted in long-term use procedure medi-spring one end, make switch failure.
The utility model is further set to: on described segmented disc wall, closed guard is set, and is structure as a whole with segmented disc.
By adopting technique scheme, save the protective cover of peripheral hardware, and the setting of integrative-structure, make the structure of circuit changing switch simpler.
The utility model is further set to: described segmented disc base also arranges conversion equipment, and described conversion equipment is mainly made up of rotor and rotating shaft, and described rotor is set in described rotating shaft.
By adopting technique scheme, can realize the separating, merging dynamic and static contact to change over switch.
The utility model is further set to: described movable contact body is provided with the groove that holds movable contact spring and spring, described movable contact spring both sides are provided with moving contact, described touch device also includes wiring member, described wiring member is the conductor strip that connects internal wiring and extraneous wire, described wiring member one end is provided with fixed contact, and the other end is provided with through hole.
By adopting technique scheme, can effectively fix the other end of Compress Spring, ensure that switch uses more lastingly, movable contact spring is arranged in moving contact groove, can in the time that segmented disc wall moves, dynamic and static contact be disconnected simultaneously at moving contact, wiring member one end arranges through hole, can being connected and fixed for external wire.
Compared with prior art, the utility model advantage is:
Pass through detent mechanism, make Compress Spring that skew in use can not occur and cause switch failure, enclosed segmented disc simultaneously, change over switch is moved under the environment of relative closure, so can guarantee that switch is normal, stablize and operation effectively, improve the physical life of circuit changing switch.
