Embodiment:

The utility model includes protecgulum 10 and egative film 20, and protecgulum 10 adopts insulating material to make.Protecgulum 10 is fixed on the egative film 20, and protecgulum 10 has fixed touching plate 30, movable contact spring 40 and spring 42 with the space internal fixation that egative film 20 surrounds, and fixed touching plate 30 is fixed on the egative film 20, and an end of spring 42 connects movable contact spring 40, and the other end is fixed on the egative film 20.The utility model also includes the magnet 50 that cooperates with movable contact spring 40.

Rotating shaft 12 is housed on the protecgulum 10, and movable contact spring 40 is connected with rotating shaft 12 and can 12 rotates around the shaft.

Fixed touching plate 30 of the present utility model is a metal wire, and movable contact spring 40 is an iron plate, to realize contacting and disconnection of movable contact spring 40 and fixed touching plate 30.Certainly, fixed touching plate 30 also can adopt other conducting element.

Fixed touching plate 30 and spring 42 are drawn lead by egative film 20 respectively, external power supply 60 and electrical appliance 70, and fixed touching plate 30 and spring 42 all can conduct electricity.

The utility model can be realized by following several modes:

One: see Fig. 1, fixed touching plate 30, spring 42 lay respectively at the both sides of rotating shaft 12.

When magnet 50 was taken away, movable contact spring 40 was because the elastic force effect that gravity of self and spring 42 make progress, and its left end is sagging to contact conduction with fixed touching plate 30;

See Fig. 2, when being put in magnet 50 on the protecgulum 10 and placing the top of movable contact spring 40 left ends, movable contact spring 40 12 rotates around the shaft, and movable contact spring 40 is attracted by magnet 50 and upwards flicks, and left end upwards disconnects with fixed touching plate 30, and pressing spring 42 under the right-hand member.

Two: see Fig. 3, fixed touching plate 30, spring 42 are positioned at the same side of rotating shaft 12.When magnet 50 was taken away, movable contact spring 40 was because the elastic force effect that gravity of self and spring 42 make progress, movable contact spring 40 12 rotations around the shaft and disconnecting with fixed touching plate 30;

See Fig. 4, when being put in magnet 50 on the protecgulum 10 and placing movable contact spring 40 left ends when top, its left end is subjected to the attraction of

magnet

50 and 12 rotations around the shaft, upwards swing of left end, and pressing spring 42 under the right-hand member, until contacting conducting with fixed touching plate 30.

The utility model can also adopt the mode of fixed magnet 56 on movable contact spring 40, for example:

Three: see Fig. 5,6, by outside protecgulum 10, moving the effect that opposite polarity magnet 52 reaches circuit turn-on and disconnection.
