Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

[embodiment 1]

To shown in Figure 3, a kind of ball switch comprises external conductive casing 1, conduction ball 2, insulation chock 3 and conducting terminal 4 as Fig. 1.

This external conductive casing 1 is made by electric conducting material.The whole one-tenth of this external conductive casing is cylindric, and the one end is provided with an opening.

This conduction ball 2 is also made by electric conducting material.2 one-tenth spheroidals of this conduction ball, its smooth surface.This conduction ball is contained in this external conductive casing.

One insulation chock 3 is cylindrical, is installed in the opening of this external conductive casing, the openings of sizes of this external conductive casing 1 of size coupling.This insulation chock 3 is sealed the opening of this external conductive casing 1, conduction ball 2 can only be rolled in this external conductive casing 1, and can't roll out external conductive casing.This insulation chock 3 can also use waterproof material to seal up this insulation chock integral body, makes it that water-proof function be arranged, and improves the security performance of this ball switch.

One conducting terminal 4, this conducting terminal passes the centre of this insulation chock 3, and an end extend into external conductive casing 1 inside, and the other end exposes in external conductive casing 1 outside, but does not contact with external conductive casing 1.

This ball switch is when being connected into circuit, and this external conductive casing 1 extremely links to each other with circuit one, and another extremely links to each other conducting end 4 sons with circuit.When the part in conduction ball 2 and the conducting terminal 4 insertion external conductive casings 1 contacts, just conducting terminal 4 and external conductive casing 1 are electrically connected, thereby the circuit of connection external conductive casing 1 and conducting terminal 4 is linked together the connection of this ball switch just (ON) state.When ball away from conducting terminal the time, conducting terminal 4 just is not electrically connected with external conductive casing 1, thereby the circuit of connection external conductive casing 1 with conducting terminal 4 disconnected, and this is the state of this ball switch closure (OFF) just.

The utility model can be regulated conduction ball 2 sizes, the distance between conduction ball 2 and the conducting terminal 4 as required.Can determine like this how many angles this switch is swung and allowed conduction ball 1 contact with conducting terminal 4, thereby make this ball switch enter connection (ON) state.That is to say the distance that has changed between conduction ball 1 and the conducting terminal 4, changed sensitivity of the present utility model and responsiveness exactly.

[embodiment 2]

As shown in Figure 4 and Figure 5, be second embodiment of the present utility model, the difference of itself and embodiment 1 is further to set up a metallic sheath 5 between conduction ball 2 and external conductive casing 1.This metallic sheath 5 is cylindric, and coupling ground is contained in the external conductive casing 1, and the outer surface of metallic sheath 5 contacts with external conductive casing 1, inner surface with conduct electricity ball 2 and contact, and be insulated chock 3 and be enclosed in this external conductive casing 1 with conducting electricity ball 2.This metallic sheath can improve the contact performance of product, better guarantees the connection of ball switch to circuit.
