Abstract
The utility model relates to a magnetically controlled, safely used switch which can be used safely. A sealing shell is adopted to seal a push-button switch and a magnetic rotary arm, and a magnetic push button located on the outer surface of the sealing shell can move along a slide way. A magnet end which is fixed on the magnetic rotary arm can revolve around the other end, and when the magnetic push button moves towards the magnet end of the magnetic rotary arm along the slide way, the magnet of the magnetic rotary arm can revolve around the other end under the function of the magnetic force of the magnetic push button to switch on or off a push button of the push button switch. Consequently, the switch-on and switch-off of the circuit occur inside the sealing shell, so the electric shock hazard cannot occur or fire accidents cannot occur due to flammable gas ignited by electric sparks produced by switch contact, and thereby the purpose of safe use is realized. The switch is mainly used as a circuit control switch used under flammable gas environments such as oil depots and filling stations, the circuit switch of mines and a switch used under damp environments, such as a bathroom light switch and the circuit control switch of a washing machine.
Description
Affiliated technical field
The circuit controling switch that can use safely when the utility model relates to a kind of control circuit, especially the magnetic control that can use safely under the environment that moist, burn into have fuel gas to exist is used switch safely.
Background technology
At present, known circuit controling switch, the secure closed measure is bad, can only can use safely under conventional environment.But,, can cause Danger Electric shock risk or fuel gas and breaking out of fire accident because the electric spark that the switch contact produces ignites as having under the fuel gas environment at moist, burn into.
Summary of the invention
In order to overcome existing circuit controling switch, cause Danger Electric shock risk easily and because switch contact the electric spark of generation ignite fuel gas and the weak point of breaking out of fire accident, the utility model provides a kind of magnetic control safe handling switch, Danger Electric shock risk not only can not take place in this magnetic control safety switch, nor understands the fuel gas because the electric spark that the switch contact produces ignite and the breaking out of fire accident.
The technical scheme that the utility model technical solution problem is adopted is: the shell of sealing is closed push-button switch, push-button switch and band magnetic acitvity arm, the outside that the binding post of push-button switch is positioned at closure is connected with the electric wire of control circuit, and the band magnetic button of closure outer surface can move along sliding tray.Band magnetic cursor is fixed with magnet end and can rotates around the other end, turns an angle and can the button of push-button switch be opened and closed.When band magnetic button along sliding tray when band magnetic cursor carry magnet one end moves, the magnet of band magnetic cursor rotates and the button of push-button switch is opened and closed at the band magnetic button magneticaction lower edge other end.Like this, the keying of circuit occurs in closure inside, thus Danger Electric shock risk can not take place or because the electric spark that switch contact produces ignites fuel gas and breaking out of fire accident, reach the purpose of safe handling.
The beneficial effects of the utility model are: can not only be applied under the conventional environment, and can have fuel gas to exist under the complex environment at moist, burn into to use, Danger Electric shock risk can not take place or because the electric spark that switch contact produces ignites fuel gas, reach the purpose of safe handling.
