Abstract

The utility model relates to a magnetic-controlled switch comprising a bottom piece on which an electricity conducting support frame is fixed. The electricity conducting support frame is connected with one electrode of a power supply, and a movable contact piece is hinged on the electricity conducting support frame and is matched with a magnet which controls the movable contact piece to be connected or disconnected with the other electrode of the power supply. An elastic member is fixed on the bottom piece, one end of the movable contact piece is connected with the elastic member and the other electrode of the power supply is fixed on the bottom piece through an electric appliance. The utility model controls the movable contact piece to rotate by putting a magnet on or off from a position above the movable contact piece, so that the movable contact piece is connected or disconnected with the other electrode of the power supply, and then the movable contact piece, the electricity conducting support frame, the power supply and the electric appliance form an electric current loop or open loop. The utility model controls a circuit by moving the magnet and has the advantages of simple structure and convenient use. The utility model can interest children.

Description

Magnetic switch

Technical field:

The utility model relates to the switching technique field, refers in particular to a kind of magnetic switch simple in structure, easy to use.

Background technology:

The application of magnetic switch is very wide, and as antitheft door, cabinet etc., as common magnetic switch, its structure is comparatively complicated, and every requirement is all very high.Much be fit to the e-book that children use and developed in the market, circuit by configuration reaches the effect of reading aloud, to improve children's learning interest, and on these small-sized e-book and some other toy, adopt above-mentioned general magnetic switch, can increase manufacturer's production cost greatly, and the magnetic switch of complexity is applied on the small electrical philosophical works and the toy also is very inconvenient.

Summary of the invention:

The purpose of this utility model is to provide a kind of magnetic switch simple in structure, easy to use at the deficiencies in the prior art, and it can be applied on the small electrical philosophical works and other toys for children.

For achieving the above object, the utility model adopts following technical scheme: it includes egative film, is fixed with conducting bracket on the egative film, and conducting bracket links to each other with an electrode of power supply, is hinged with movable contact spring on it; This movable contact spring is combined with the magnet of another utmost point break-make of a control movable contact spring and power supply.

Be fixed with elastic component on the described egative film, an end of movable contact spring is connected with elastic component.

Another utmost point of described power supply is fixed on the egative film via electrical appliance.

Described movable contact spring contact upper fixed has sheet metal, and sheet metal connects another utmost point of power supply.

The utility model is by placing or take away magnet above movable contact spring, control the rotation of movable contact spring, thereby another electrode that makes movable contact spring and power supply connects or disconnects, and then makes movable contact spring, conducting bracket, power supply, electrical appliance constitute a current circuit or disconnection.Realize control by moving magnet to circuit, simple in structure, easy to use, can promote children's interest.

Embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.

See Fig. 1,2, it includes egative film 2, be fixed with conducting bracket 5 on the egative film 2, movable contact spring 4 activities are fixed on the conducting bracket 5, conducting bracket 5 connects an electrode of power supply 7, and it also includes the magnet 1 that cooperates with movable contact spring 4, by moving magnet 1, make it pick up movable contact spring 4 or disconnection, thereby realize another utmost point conducting or disconnection of movable contact spring 4 and power supply 7.Movable contact spring 4 is a conducting element, can directly conduct electricity between it and the conducting bracket 5.

Be fixed with elastic component 6 on the egative film 2, an end of movable contact spring 4 is connected with elastic component 6, and elastic component 6 can be sponge, rubber-like working of plastics and other elements.

Another utmost point of power supply 7 is fixed on the egative film 2 via electrical appliance 8, and the contact of this electrode is revealed on the egative film 2, and an end of movable contact spring 4 can contact with the contact of this electrode.

See Fig. 1, the schematic diagram during for the first embodiment conducting of the present utility model; Another electrode of power supply 7 and elastic component 6 are fixed on a side of conducting bracket 5, when magnet 1 moves to the opposite side of conducting bracket 5, this end of movable contact spring 4 is picked up, around conducting bracket 5 rotations, movable contact spring 4 other ends press down, and contact conducting with the electrode of its below, and power supply 7, electrical appliance 8, movable contact spring 4, conducting bracket 5 constitute a current circuit at this moment, electrical appliance 8 work, and elastic component 6 is compressed.

Seeing Fig. 2, is the schematic diagram of first embodiment of the present utility model when disconnecting; Remove magnet 1, elastic component 6 resets, and with top on the movable contact spring 4, movable contact spring 4 and electrode is disconnected, and circuit is disconnected, and electrical appliance 8 quits work.

Fig. 3, the 4th, the schematic diagram when second embodiment conducting of the present utility model and disconnection; Another electrode of power supply 7 and elastic component 6 are separately fixed at the both sides of conducting bracket 5, so its operation principle is similar to above-mentioned first embodiment, just do not give unnecessary details one by one here.

Schematic diagram when Fig. 5 is the 3rd embodiment conducting of the present utility model; In movable contact spring 4 contact upper fixed sheet metal 9 is arranged, sheet metal 9 connects another utmost point of power supply 7.When magnet 1 moved to movable contact spring 4 tops, this end of movable contact spring 4 was picked up, and connected with sheet metal 9, and power supply 7, electrical appliance 8, movable contact spring 4, conducting bracket 5, sheet metal 9 constitute a current circuit at this moment, electrical appliance 8 work, and elastic component 6 is compressed.
