Abstract
The utility model discloses a non -contact speed governing switch, include: handle, magnetic element, circuit board are pressed to the switch, magnetic element connects in the handle is pressed to the switch, be provided with hall element and pressure sensor on the circuit board, hall element or pressure sensor are the realization modes of two kinds of differences, but in the realization mode of difference, pressure sensor and hall element will place the different positions of pressing handle button stroke at the switch. Its pressure sensor sets up in the lower part of circuit board, and its hall element sets up the avris at the circuit board, through above -mentioned mode, the utility model discloses the switch contact is stable, long service life.
Description
Technical field
The utility model relates to potentiometer switch technical field, particularly relates to a kind of contactless speed-regulating switch.
Background technology
At present, existing various speed-regulating switch, its switch internal has the potentiometer of a contact usually, general potentiometer is made up of the handle of brush, carbon film or grading resistance and shifting brush, by migration potential device handle, change resistance, thus realize speed-regulating function; Because adopting contact brush structure, under height vibrations condition, brush, golden finger or the carbon film life-span low.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of contactless speed-regulating switch, switch contact stabilization, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of contactless speed-regulating switch, comprise: switch press handle, magnetic element, wiring board, described magnetic element is connected in switch press handle, described wiring board is provided with Hall element or pressure sensor, the diverse location of switch press lever knob handle will be placed between described pressure sensor or Hall element, described pressure sensor is arranged on the bottom of circuit board, and described Hall element is arranged on the avris of circuit board.
In the utility model preferred embodiment, described moving handle is a switch press handle, and described switch press handle connects a moveable combination of guide rod.
In the utility model preferred embodiment, described Hall element is arranged on the right side of moveable combination of guide rod, and described pressure sensor is arranged on the below of moveable combination of guide rod.
In the utility model preferred embodiment, described magnetic element is arranged on the middle part right side wall of moveable combination of guide rod.
The beneficial effects of the utility model are: the utility model adopts noncontact pressing mode, and structure is simple and easy to operate, and under height vibrations condition, the useful life extending switch is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model contactless speed-regulating switch one preferred embodiment;
Fig. 2 is the structural representation of contactless another preferred embodiment of speed-regulating switch of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, switch press handle; 2, magnetic element; 3, wiring board; 10, moveable combination of guide rod; 30, Hall element; 31, pressure sensor.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises: a kind of contactless speed-regulating switch, comprise: switch press handle 1, magnetic element 2, wiring board 3, described magnetic element 2 is connected in switch press handle, described wiring board 3 is provided with Hall element 30 and pressure sensor 31, described pressure sensor 31 is arranged on the bottom of circuit board 3, and described Hall element 30 is arranged on the avris of circuit board 3.
Furtherly, described switch press handle 1 is a moving handle, and described switch press handle 1 connects a moveable combination of guide rod 10; Described Hall element 30 is arranged on the right side of moveable combination of guide rod 10, and described pressure sensor 31 is arranged on the below of moveable combination of guide rod 10; Described magnetic element 2 is arranged on the middle part right side wall of moveable combination of guide rod 10.
The operation principle of the contactless speed-regulating switch of the utility model, when in moving switch pressing handle 1 moving process, Hall element 30 senses that the magnetic power of magnetic element 2 changes, corresponding hall output voltage change, after this voltage signal is transferred to single-chip microcomputer, also there is respective change in switched voltage output, thus realizes speed-regulating function; Or when after moving switch pressing handle 1, pressure sensor 31 senses that pressure changes, and pressure sensor 31 output voltage changes, and after this voltage signal is transferred to single-chip microcomputer, switched voltage output also respective change occurs, thus realizes speed-regulating function.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
