Description
Technical field
The utility model belongs to field of switches, particularly relates to a kind of knob driving switch.
Background technology
Existing rotary switch often will have flexible static contact and be arranged on switch base, movable contact spring is arranged on switch shaft, movable contact spring is made to be connected with static contact or to disconnect by rotating switch axle, but be provided with spring below each static contact of the switch of this structure, this just makes this switch inefficiency when installation, and production cost is high.
Utility model content
The purpose of this utility model be complicated for existing knob gear switch structure, installation effectiveness is low and a kind of knob driving switch of providing.
The utility model is achieved by the following technical solution:
Knob driving switch, comprises pedestal and knob, pedestal has conductive pole, conductive pole one end protrudes from pedestal end face and arranges, and extend in knob, there is multiple binding post in pedestal, there is in pedestal a disc spring, the pedestal of disc spring upper end has multiple conductive contact, conductive contact lower end contacts disc spring, and each conductive contact is electrically connected a binding post respectively, and conductive contact is connected with pedestal relative sliding, knob lower surface is provided with conducting strip, conducting strip electrical connection conductive pole.
In knob, be positioned at conductive pole upper end be provided with a conductor ball, also comprise a connecting piece, spheroid contacts brace, and make both realize electrical connection, brace is electrically connected conducting strip by wire.
Described conducting strip is the metallic conduction sheet of an indent.
The upper surface of described conductive contact is hemispherical dome structure.
The beneficial effects of the utility model: the utility model structure is simple, and original single spring design is become disc spring, make the utility model structure more simple, make it easier, quick when installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1, knob driving switch, comprise pedestal 1 and knob 2, it should be noted that, on pedestal 1, there is conductive pole 3, conductive pole 3 one end protrudes from pedestal 1 end face and arranges, and extend in knob 2, there is multiple binding post 4 in pedestal 1, have a disc spring 5 in pedestal 1, the pedestal 1 of disc spring 4 upper end has multiple conductive contact 6, conductive contact 6 lower end contacts disc spring 5, each conductive contact 6 is electrically connected a binding post 4 respectively, conductive contact 6 is connected with pedestal 1 relative sliding, and knob 2 lower surface is provided with conducting strip 7, and conducting strip 7 is electrically connected conductive pole 3.
It should be noted that in knob 2, be positioned at conductive pole 3 upper end is provided with a conductor ball 8 further, also comprise a connecting piece 9, spheroid 8 contacts brace 9, both are made to realize electrical connection, the design of spheroid 8 is in order to can be movable preferably between knob 2 and conductive pole 3, and brace 9 is by wire electrical connection conducting strip 7.Described conducting strip 7 is the metallic conduction sheet of an indent.
Further it should be noted that the upper surface of described conductive contact is hemispherical dome structure.
The utility model will arrange a disc spring 4 in pedestal, and be arranged in pedestal 1 by a pressing plate 10, disc spring 4 arranges conductive contact, disc spring has top power upwards to all conductive contacts all the time, better can contact with conducting strip, when knob be threaded to conductive contact contact conducting strip to knob time, conductive contact slightly moves upward, contact contacts conducting strip indent part, and contact has certain resistance and stops knob to continue to rotate, and makes the feel of user better.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection range of the present utility model.
