Power switch, electron pressure switch etc..
Magnet assembly 13 can be the component that can arbitrarily generate magnetic field, for example, permanent magnet, hot-wire coil etc..Fig. 1
Illustrated so that magnet assembly 13 includes the first permanent magnet 131 and the second permanent magnet 132 as an example.
Wherein, the first permanent magnet 131 is opposite with the magnetic pole of the second permanent magnet 132；First permanent magnet 131 and the second permanent magnetism
Iron 132 is oppositely arranged in a second direction, and the angle between second direction and first direction is greater than zero.
It is 90 degree in Fig. 1 with the angle between second direction and first direction to be illustrated.In addition, N north-seeking pole, S in Fig. 1
South pole, the magnetic direction that magnet assembly 13 generates are the direction that N is directed toward S.
Specifically, arcing sense of current is first party when generating phenomenon of arc discharge between the first contact 11 and the second contact 12
To, i.e. horizontal direction in Fig. 1, the angle between the magnetic direction and first direction that are generated due to magnet assembly 13 is greater than zero, because
There is magnetic-field component in this, to can produce the ampere being not zero under the influence of a magnetic field in a direction perpendicular to the first direction
Power.The direction of Ampere force is vertical with arcing electric current and magnetic direction, so as to change arcing sense of current, by arcing distance
Elongation has the function that fast arc extinction, realizes the protection to contact, extends the service life of pressure switch.
In a kind of preferably way of realization, the magnetic direction that magnet assembly 13 generates can hang down mutually with first direction

Face and the position of downside, etc. for being located at the first contact 11 and the second contact 12.
It further, can also include controller in pressure switch 10, for according to the electric current flowed through in pressure switch 10
The current value of electrified wire 133 is flowed through in value, control.
Specifically, if it is determined that can then increase when the current value flowed through in pressure switch 10 is larger and flow through electrified wire 133
Current value；If it is determined that then can reduce the electric current for flowing through electrified wire 133 when the current value flowed through in pressure switch 10 is smaller
Value.
It is understood that in general, the magnetic field size of the generation of electrified wire 133 and the electric current for flowing through electrified wire 133 are big
It is small directly proportional.When the current value flowed through in pressure switch 10 is larger, the drawing that is generated between the first contact 11 and the second contact 12
Arc current is also corresponding larger, and the current value of electrified wire 133 is flowed through by increasing, the magnetic field that electrified wire 133 can be made to generate
It is stronger, to generate bigger Ampere force, and then make the speed of arc extinguishing faster.When the current value flowed through in pressure switch 10 is smaller
When, the arcing electric current generated between the first contact 11 and the second contact 12 is also corresponding smaller, leads at this point it is possible to reduce and flow through energization
The current value of line 133, to can reduce the consumption of energy while guaranteeing the effect of fast arc extinction.
It further, can also include power supply, for providing electricity for electrified wire 133 in the utility model embodiment
Stream.
In addition, can also include current monitoring component, flow through pressure switch for monitoring in the utility model embodiment
10 electric current, so that controller can control the electricity for flowing through electrified wire 133 according to the size of current of current monitoring assemblies monitor
Flow valuve.
