Abstract
The utility model provides a photosensitive reflection type multi-throw switch. The switch comprises a base plate, a housing cover and a knob. Small holes are arranged at four corners of the base plate, corresponding to small holes at four corners of the housing cover. The base plate has a light source area and a photoresistor area, and is provided with a hollow cylindrical projection for a rotating shaft of the knob to be plugged into. A knob port, a wire inlet and a wire outlet are arranged on the housing cover. The knob is composed of a rotating handle, the rotating shaft and a planar reflective mirror, wherein the planar reflective mirror is fixed on the rotating shaft. The beneficial effects of the utility model are that the use of the switch is safe, and people is prevented from directly contacting high voltage; and the switch can be used for controlling multiple circuits.
Description
Technical field
The utility model relates to a kind of switch, particularly relates to a kind of photosensitive reflective switches of putting more.
Background technology
Hotel guest-room is often used plug-in card charging type switch, but the switch usually using in family is button, often directly to be connected on the circuit of electrical appliance, dangerous in the time of can causing like this touching switch, the utility model utilizes the large electric current of Small current control to make use safer by photo resistance special efficacy just, and can control different circuit by the position difference of knob.
Utility model content
The technical solution of the utility model: a kind of photosensitively reflectively put switch more, it is characterized in that: it is to consist of base plate, casing cover and knob; On described base plate four jiaos to have the aperture having on four jiaos of aperture and casing covers corresponding, base plate is provided with source region and photo resistance region, is also provided with hollow cylinder projection and inserts to hold the rotating shaft of knob on base plate; On described casing cover, have knob mouth, incoming line and line outlet; Described knob forms by rotating handle, rotating shaft and plane mirror, and plane mirror is fixed on rotating shaft.
As this novel further improvement, photo resistance region consists of a plurality of photo resistance control circuits, and the photo resistance in photo resistance control circuit is towards difference; Source region and photo resistance region occupy plane mirror one side, and source region is for producing LASER Light Source circuit.
Superiority of the present utility model: make the use of switch avoid more safely people directly to touch high voltage, and can control a plurality of circuit.

Embodiment
As shown in drawings: a kind of photosensitively reflectively put switch more, it is characterized in that: it is to consist of base plate 1, casing cover 2 and knob 3; On described base plate 1 four jiaos to have the aperture 5 having on 2 four jiaos of aperture 4 and casing covers corresponding, base plate 1 is provided with source region 6 and photo resistance region 7, is also provided with hollow cylinder projection 8 and inserts to hold the rotating shaft 9 of knob 3 on base plate 1; On described casing cover 2, have knob mouth 10, incoming line 11 and line outlet 12; Described knob 3 by rotation 13, rotating shaft 9 and plane mirror 14 form, plane mirror 14 is fixed on rotating shaft 9.
As this novel further improvement, photo resistance region 7 consists of a plurality of photo resistance control circuits 15, and the photo resistance in photo resistance control circuit 15 is towards difference; Source region 6 and photo resistance region 7 occupy plane mirror 14 1 sides, and source region 6 is for producing LASER Light Source circuit 16.
Using method of the present utility model is: when this switch uses, for being horizontally fixed in plane, in the time of opening switch, first the switch opens of controlling circuit of light sources, more knob is turned round to different positions be the different circuit of connection.
Operation principle of the present utility model is to utilize the photoelectric characteristic of photo resistance, wherein photo resistance of the present utility model is for a little less than having incident light, resistance reduces, incident intensity, resistance increases the photo resistance of characteristic, first when producing beam of laser, source region is radiated on the plane mirror of knob, so laser beam changes light path by plane mirror, under suitable angle, laser beam is finally beaten in one of them photo resistance of photo resistance control circuit, so the resistance of photo resistance becomes the situation that has made greatly to change the original thresholding ground connection of diode, make circuit turn-on, in the time will connecting another road, rotating knob impinges upon in the photo resistance on this road laser beam, so this road is with regard to conducting.
