Description of drawings

Relevant detailed structure of the present utility model, feature and effect below are lifted a preferred embodiment now, and conjunction with figs. is further described, wherein:

Fig. 1 is the combination stereogram of the utility model one preferred embodiment;

Fig. 2 is the exploded perspective view of the utility model one preferred embodiment.

Embodiment

See also Fig. 1 to Fig. 2, a kind of photosensitizing type multistage rotary switc 10 that the utility model one preferred embodiment is provided, mainly formed by a case 11, a circuit board 21, an armature 31, a bridge joint electric-conductor 41, three conducting strips 51, a diode 61 and a photoinduction element 71, wherein:

This case 11 is made up of a lid 12 and a base 14, and its inside has a room 16, and these base 14 two side ends are respectively established two trunkings 15 and are communicated with this room 16, and this lid 12 is provided with a loophole 13;

This circuit board 21 is arranged in this room 16 and is positioned at an end of this base 14, is connected in first, second electric wire 91,92;

This armature 31 is embedded at this lid 12;

This bridge joint electric-conductor 41 is sheathed on this armature 31, and the side face of this armature 31 is equipped with: two bridge joint conductive parts 42 and an insulation division 44; This armature 31 and this bridge joint electric-conductor 41 are to be located in this room 16, and must be subjected to dial changes;

These conducting strips 51, be located in this room 16, first conducting strip 511 is to be connected in this circuit board 21, and be connected with first electric wire 91, second, third conducting strip the 512, the 513rd is arranged at the other end of this base 14 and corresponding to the trunking 15 of this end, second conducting strip 512 is to be connected in the 3rd electric wire 93, and these conducting strips 51 also are located on around this bridge joint electric-conductor 41, cooperate these bridge joint conductive parts 42 and this insulation division 44 to produce different conduction states;

This diode 61 is located in this base 14, and its two end is to be connected with second, third conducting strip 512,513, and the pressure drop effect is provided;

This photoinduction element 71, be to be a photo resistance in the present embodiment, be located at this circuit board 21, and be connected in first, second electric wire 91,92, when this lid 12 covers this base 14, photoinduction element 71 is just corresponding to the position of this loophole 13, produces switch motion in order to the lightness in the sensing external world.

The one enforcement state of the utility model 10 is to make the circuit of this photoinduction element 71 be state in parallel with the circuit of this circuit board 21, when this photoinduction element 71 measures the light source deficiency in induction, its circuit promptly is path, and it measures light source when sufficient, and its circuit promptly is off state.

The utility model 10 is when using, and extraneous light source just can see through this loophole 13 and enter in this lid 12, so that make this photoinduction element 71 be able to the brightness in the sensing external world.In the time of by day, the user cuts off circuit of the present utility model, and simultaneously, this photoinduction element 71 also senses sufficient light, and therefore, its circuit all is off state.When night,, promptly can switch to conducting state, so that energized makes the bulb of light fixture shinny in case this photoinduction element 71 senses indoor light source when not enough.After the user goes home, cut this armature 31 and make its circuit form channel status, because the changeable different conduction state of the utility model provides different resistance values, therefore adjusted the brightness of light fixture.

Photoinduction element 71 of the present utility model does not exceed with connection status in parallel with 21 of this circuit boards, also must be designed to execution modes such as series and parallel, or series connection.

Via above structure, when indoor light deficiency or night, promptly automatically in the illuminating chamber, when the user returned home, indoor was to be bright state with the light fixture that is provided with the utility model 10, also come to have in the generating chamber people's vacation picture thus, reduce the probability of robber's invasion.

In sum, photosensitizing type multistage rotary switc of the present utility model, it has the aforementioned advantage that is better than prior art, meets patent condition, so file an application in accordance with the law.
