Abstract
Provided is a switch device, comprising a case and a base at the bottom of the case. The switch device is characterized in that an axially-rotatable button is arranged in the case, a magnet is mounted at the bottom of the button, and a magnetic induction switch which is conducted under the effect of the magnetic field of the magnet is disposed in the base. Compared with the prior art, the utility model is advantageous in that the magnetic induction structure is adopted to replace a conventional wafer-type contact structure, and the magnetic induction switch can be conducted when the magnetic field is induced, enhancing the switch sensitivity; in addition, the magnetic induction switch and the magnet generating the magnetic filed are accommodated in a sealed cavity formed by the case and the base, avoiding the effect of outside pollution on the switch application, increasing the anti-interference ability of the switch, prolonging the service lifetime of the switch and guaranteeing normal operation of devices.
Description
Technical field
The utility model relates to a kind of switching device, particularly a kind of switching device that is used for water detection leakage equipment.
Background technology
At present; The switching device that is used for water detection leakage equipment normally adopts the mode of contact contact to carry out the switch switching, because the operational environment pollution of water detection leakage equipment is comparatively serious, the influence that the contact of switching device receives factors such as water, greasy dirt, dust is bigger; After long-time the use; Contact can cause the loose contact of switching device because of pollution, thereby makes the sensitivity of switching device reduce, and can't guarantee the normal use of equipment.
The utility model content
The utility model technical problem to be solved is to above-mentioned prior art present situation a kind of switching device that environmental pollution is little and sensitivity is higher that receives to be provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this switching device; Include housing and the base that is arranged at this housing bottom; It is characterized in that: being provided with in the described housing can axially movable button; The bottom of this button is equipped with magnet, be provided with in the said base can conducting under the action of a magnetic field of said magnet magnetic induction switch.
As preferably, described button also is provided with and can drives the elastic component that this button upwards resets all the time, and an end of said elastic component links to each other with said base, and the other end of this elastic component links to each other with the magnet that is positioned at said button bottom.
Compared with prior art, the advantage of the utility model is: replace existing contact formula contact structures with the magnetic induction structure, magnetic induction switch is in that just sense under the situation in magnetic field can conducting, the sensitivity that has improved switch; And; Magnetic induction switch and the magnet that produces magnetic field with it are placed in the closed cavity that is formed by housing and base, can avoid outside contamination to the influence that switch uses, and have improved the antijamming capability of switch; Prolong the useful life of switch, guaranteed the normal use of equipment.
Description of drawings
Fig. 1 is the switching device structural representation of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the switching device of present embodiment includes housing 1, panel 2 and base 3, wherein; Panel 2 is fixedly connected on the base 3 through screw 7; Housing 1 is provided with panel 2 tops, is provided with the round button 4 that can push in the housing 1 downwards, and this round button 4 is embedded in the housing 1 and can in housing 1, moves up and down; Button 4 is equipped with magnet 5 in the bottom, be provided with the magnetic induction switch 6 that can produce magnetic field induction with magnet 5 in the base 3;
Also be provided with on the button 4 and can drive the make progress elastic component of elastic reset of this button, this elastic component is a spring 51, and an end of spring 51 links to each other with panel 2, and the other end of this spring 51 links to each other with magnet 5.
During use, press the button 4 and reach certain position, be positioned at magnetic induction switch 7 on the base 3 after sensing the magnetic field that magnet 5 produces, switch closure, circuit turn-on;
When decontroling button 4, button 4 upwards resets under the reaction force of spring 51, and magnet 5 also moves upward thereupon, and at this moment, magnet 5 is away from magnetic induction switch 6, and the magnetic field that is produced is not enough to keep the closure of magnetic induction switch 6, and switch breaks off.
The above only is the preferred implementation of the utility model; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
Claims (2)
