Abstract
The utility model discloses a magnetic force on-and-off switch whose casing forms two cavities, namely an upper cavity and a lower cavity. Two contacts are mounted on the cavity body at the upper partof the upper cavity, and extend out the upper cavity of the casing but into the inside of the upper cavity; the lower ends of the two contacts are aligned; a permanent magnet is arranged in the uppercavity and in sliding fit with the inner wall of the upper cavity; an electric conductor is fixed at the upper part of the permanent magnet; three linkage permanent magnets with same lengths are mounted in the lower cavity; the polarities of the three permanent magnets are opposite to one another, wherein the permanent magnet in the middle has the polarity opposite to that of the permanent magnetin the upper cavity; a handle is fixed at the lower part of the permanent magnet; the lower cavity is as long as four permanent magnets in together; the three permanent magnets are in sliding fit with the inner wall of the lower cavity; and a handle moving groove is formed on the casing at the lower part of the lower cavity. When the three permanent magnets are located in left position or the right position, one of the three permanent magnets is always selected to correspond to the permanent magnet in the upper cavity from top to bottom. The magnetic force on-and-off switch is a switch with the advantages of moisture prevention, electric-shock avoidance and good contact performance.
Description
Technical field
The utility model relates to a kind of appliance switch, especially a kind of magnetic force on-off switch that is fit to be installed on the wall.
Background technology
At present, the movable contact spring of the hand switch of prior art and the contact pressure between the contact all provide by spring, because spring is after strain repeatedly, its elastic force can diminish gradually, like this, meeting loose contact between the movable contact spring of switch and contact, thus cause virtual connection even sparking.In addition, the movable contact spring of the hand switch of prior art be directly installed on handle be on the movable housing of one, such switch does not have moisture-proof function, particularly in the bathroom, because the phenomenon that switch electric leakage causes the person to get an electric shock and die happens occasionally.So designing all good appliance switch of a kind of humidity resistance and contact performance is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of humidity resistance and all good magnetic force on-off switch of contact performance.
The technical scheme in the invention for solving the technical problem is:
A kind of magnetic force on-off switch, by housing, contact, break-make body and handle are formed, housing forms two chambeies, epicoele and cavity of resorption, two contacts are installed on the cavity on epicoele top, it is outer and put in the epicoele that contact stretches out the epicoele of housing, the bottom of two contacts is concordant, in epicoele, be provided with permanent magnet, the inwall of permanent magnet and epicoele is slidingly matched, top at permanent magnet is fixed with electric conductor, the permanent magnet of the interlock that three block lengths equate is installed in cavity of resorption, and the polarity of three permanent magnets is opposite each other, wherein in the middle of the interior permanent magnet polarity of permanent magnet and epicoele opposite, described handle is fixed on the bottom of permanent magnet, the length of cavity of resorption is the length of four permanent magnets, and three permanent magnets are slidingly matched with following cavity wall, and the housing of cavity of resorption bottom is provided with the handle loose slot, when three permanent magnets in the cavity of resorption are in position, a left side or right position, there is the interior permanent magnet of a permanent magnet and epicoele corresponding up and down all the time.
The technical scheme in the invention for solving the technical problem can also be:
Three permanent magnets in the cavity of resorption described in the utility model are embedded in the caulking groove of slider case, and described handle is arranged on the bottom of slider case.
The beneficial effects of the utility model are:
Because movable contact spring and contact directly do not contact each other with handle in an independent closed chamber, so its moistureproof protection against electric shock performance is fabulous, again because movable contact spring is to contact under magneticaction with contact, so its contact performance is good, no virtual connection phenomenon takes place.
