Description

Light-operated rocker switch

Technical field:

The utility model relates to the electric switch product technical field, refers in particular to a kind of light-operated rocker switch.

Background technology:

Electric switch is the device of commutation circuit switch, and it is widely used in the various electric equipments.Traditional electric switch mostly is mechanical structure, needs artificial the triggering to make its work, will cause some problems like this, and for example: the lighting in some place is not usually closed switch for forgeing owing to the people, causes power wastage.At this situation, at present some delay switchs that can extinguish have automatically also appearred, and this switch makes switch closure by acoustic control or touch sensible, and automatic disconnection behind certain hour, for example this switch of many employings in the corridor of mansion.Though this switch has overcome some deficiency of before-mentioned products, its part that still comes with some shortcomings, that is, it does not have the long-time energising of mechanical switch or the function of outage.

Summary of the invention:

The purpose of this utility model is to overcome the deficiency of the said goods, and a kind of kinetic energy of existing standard machinery switch is provided, but has the light-operated rocker switch of automatic closing function again.

The utility model is achieved by the following technical solution: it comprises that a box body as switch main body, is articulated in button and on the box body and is fixed on circuit board on the box body, and a support is positioned at the below of button, and this support is electrically connected with circuit board; Seesaw is movably placed on the support, and be respectively arranged with in the support both sides be electrically connected with circuit board and with the corresponding contact point in two ends, the seesaw left and right sides; The button lower end is provided with a telescopic elastic slide block, and this elastic slide block presses on the seesaw; One light-sensitive element that is electrically connected with circuit board also is set in the box body.

Above-mentioned box body one end face inlay card connects a printing opacity cap, and light-sensitive element is positioned at the lower end or the next door of this printing opacity cap.

After adopting this structure, seesaw has constituted a diverter switch with the contact that is positioned at the seesaw both sides, and this diverter switch realizes the function of switching by the swing of button.Realize the conducting of different circuit by seesaw with the contact of different contacts, thereby start conventional loop (promptly directly realizing the disconnection and the closure of circuit) or light-operated loop (work that can realize load by light-sensitive element whether) by switch.

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

Fig. 1 is the utility model stereogram;

Fig. 2 is the utility model cutaway view;

Fig. 3 is the utility model three-dimensional exploded view;

Fig. 4 is the circuit diagram of the utility model one embodiment.

Embodiment:

Below only be specific embodiment of the utility model, therefore do not limit protection range of the present utility model.

See accompanying drawing 1～3, the utility model mainly comprises: box body 1, button 2, circuit board 3, support 4 and seesaw 5.Wherein box body 1 is a main body of the present utility model, a cavity in the box body 1, its upper end offers two openings, button 2 is positioned at one of them opening part, and button 2 is articulated on the box body 1, and another opening part inlay card is connected with a printing opacity cap 9, be provided with a light-sensitive element 8 below the printing opacity cap 9, on this light-sensitive element electrical connection and the circuit board 3, light is injected by printing opacity cap 9, makes light-sensitive element 8 can sense the power of extraneous light at any time.Certainly, the position of this printing opacity cap 9 can be positioned on box body 1 any one end face, senses extraneous light as long as be convenient to light-sensitive element 8.In addition, circuit board 3 is fixed on box body 1 lower surface opening part.

Support 4 be positioned at button 2 under, support 4 adopts conductive metallic materials to make, it is electrically connected with circuit board 3; Seesaw 5 places on the support 4, and this seesaw 5 is one to be down the metal flap of " people " font, and it amounts to part and place on the support 4, and promptly seesaw 5 can swing on support 4.Be respectively arranged with and circuit board 3 electrical connection and the

contact points

6,7 corresponding in support 4 both sides, when seesaw 5 swings, just can contact with contact 6 or contact 7 respectively with two ends, seesaw 5 left and right sides.

The lower ends downward of above-mentioned button 2 is extended a jut 20, offers a chute in this jut 20, and also is equipped with a spring 22 in chute, and elastic slide block 21 1 ends are inserted in this chute, and the other end presses on the upper surface of seesaw 5 under spring 22 pressure.See accompanying drawing 4, this is the circuit diagram of an embodiment of the present utility model, and seesaw 5 constitutes a diverter switch with

contact

6,7, and circuit is in off-state when seesaw 5 does not contact with contact 6 or contact 7.Circuit turn-on when seesaw 5 contacts with contact 6, conventional loop start, load (being bulb) is started working; When seesaw 5 switches to when contacting with contact 7, light-operated loop start, promptly circuit need be by a triode and light-sensitive element.Light-sensitive element 8 this moment (photo resistance) is under the relatively sufficient situation of light (for example daytime), and its resistance is very big, and bulb can't operate as normal, and promptly this moment, bulb was not luminous.Behind dim light, light-sensitive element 8 resistances reduce, and this moment, bulb just began to brighten gradually.

When using the utility model, according to circuit diagram each element in the utility model is connected, and circuit element is integrated on the circuit board 3, wherein contact 6 all is extended with the perforated portion that can be connected lead with the below of contact 7 and support 4.Under non operating state, button 2 mediates, and low pressure is at the center position place of seesaw 5 under the elastic force effect of spring 22 for elastic slide block 21 at this moment, and this moment, seesaw 5 did not contact with

contact

6,7, and circuit is in off-state, and bulb does not work.When press on button 2 right sides, promptly the elastic slide block 21 of button 2 belows is pressed on the left side section of seesaw 5 under spring 22 effects, and this moment, the left side section of seesaw 5 was depressed, and contacted with contact 6.With reference to the foregoing circuit explanation, this moment, bulb began luminous.Otherwise when button 2 is pressed left, seesaw 5 contacts with contact 7, with reference to above-mentioned explanation, this moment bulb the whether luminous control that is subjected to light-sensitive element 8, when bright and clear, bulb is not luminous.After the optical fiber dimness, bulb begins luminous.Whether like this user's diverter switch as required makes bulb both can be according to bright, the dark degree of extraneous light luminous automatically or extinguish, also can directly luminous by diverter switch direct control control bulb.
