Abstract

The utility model relates to the switch technical field, in particular to a ball switch. The ball switch comprises a seat body, a plurality of contact terminals are arranged on a side wall of an inner cavity of the seat body, a contact rolling conductor which can be contacted and communicated with adjacent two contact terminals is movably arranged in the inner cavity of the seat body, a plurality of contact terminals surround the contact rolling conductor and limit the moving space thereof. When used, the utility model is inclined, the contact rolling conductor is rolled downwards under the force of gravity and is contacted with adjacent two contact terminals at the lower side at the same time, so that functional circuits which are connected by adjacent two contact terminals are conducted, thereby the functional operation of the functional circuits is implemented. The contact rolling conductor can be contacted with different contact terminals through inclining and rotating, thereby the operation of different functions is realized. In the utility model, the operation of different functions can be realized only through inclining and rotating of the ball switch, the operation is convenient, flexible and dynamic.

Description

Ball switch

Technical field:

The utility model relates to switch, is specifically related to a kind of ball switch that is used for digital product.

Background technology:

On digital products such as MP3, MP4, mobile phone, generally all be to use key switch to realize operations such as the selection of multiple function, switching; in these feature operations, often have the operation of some subfunctions again; as when selecting music playback function for use; need also to operate that different buttons is play, stopped, next, the selection operation of subfunction such as a last head; operation inconvenience does not have new meaning.

The utility model content:

The purpose of this utility model is exactly the deficiency that exists at prior art, provides a kind of and just can realize the ball switch that difference in functionality is operated by inclination or rotation or whipping.

The utility model provides duty folding technical scheme as follows: construct a kind of ball switch, comprise pedestal, four corners at described pedestal inner chamber respectively are provided with a contact terminal, be movably set with in the inner chamber of pedestal and can contact the ball conductor with adjacent two contact terminals contact conducting, four contact terminals surround contact ball conductor and limit its activity space, and four contact terminals respectively have a pin that stretches out in the described pedestal outside.

Advantage of the present utility model is: this ball switch is installed in the circuit of electronic product, when rotation or whipping electronic product, ball in the ball switch can touch wherein two pin terminals, the circuit of these two terminals can be switched on, its function also is opened accordingly, when rotating again or during the whipping electronic product, ball can move again, thereby connect two terminals in addition, switch can be connected another functional circuit, thereby carry out the feature operation of this functional circuit, by tilting and rotation can make the touch scrolling conductor contact with different contact terminal, thereby realize the operation of difference in functionality, the utility model only need rotate or whipping just can be realized the operation of difference in functionality, and mode of operation is special.

Description of drawings:

Fig. 1 is the structure principle chart after the utility model ball switch is opened loam cake;

Fig. 2 is the front view of the utility model ball switch.

Embodiment:

With reference to Fig. 1, shown in Figure 2, a kind of ball switch is provided, it includes pedestal 1, pedestal 1 is combined by loam cake 4 and base, pedestal 1 structure that is square, four corners of pedestal 1 inner chamber respectively are provided with a contact terminal 2, each contact terminal 2 all has a pin 21 that stretches out in pedestal 1 place's side, 4 contact terminals 2 are obliquely installed four corners at pedestal 1 inner chamber, the contact-making surface of each contact terminal 2 is combined into the square space that limits contact ball conductor 3 scopes of activities mutually between 3,4 contact terminals 2 of contact ball conductor.Every group of two adjacent contact terminals 2 insert in the functional circuit, have 4 functions and can supply control operation.Be movably set with the activity space of 3,4 contact terminals of contact ball conductor, the 2 restriction contact ball conductors 3 that can contact conducting in the inner chamber of pedestal 1 with adjacent two contact terminals 2.

Contact ball conductor 3 can roll in the space that a plurality of contact terminals 2 surround under the effect of gravity or external force, under the non-working condition, contact ball conductor 3 is positioned at the center of 4 contact terminals 2, all has the gap between

contact ball conductor

3 and 4 contact terminals 2, is off-state.During use, electronic product of the present utility model will be housed to rotate or whipping, contact ball conductor 3 is under the effect of gravity or knockout press, roll downwards, and contact with adjacent two contact terminals 2 that are positioned at the below simultaneously, make these adjacent two functional circuit conductings that contact terminal 2 is connected, thereby carry out the feature operation of this functional circuit, can make contact roller pearl conductor 3 and different contact terminal 2 contacts by rotation or whipping, thereby realize the operation of difference in functionality, the utility model only need tilt and rotate the operation that just can realize difference in functionality, and is easy to operate, flexible and changeable, have innervation.Different signals is exported in the inclination of its visual main body, the variation of the anglec of rotation, can realize multinomial controlled function, and conducting is stable, and is simple in structure, easy for installation.

Contact ball conductor 3 is a kind of copper ball member.
