Description

Band switch

Technical field

The invention relates to a kind of band switch, be meant that especially a kind of switch knob attracts location and motion work done with magnetic attraction, to reach the band switch of effects such as amplification, adjusting, conversion.

Background technology

Its conductivity principle of band switch is directly to drive contact chip; A charged end is connected with a non-charged end, but has the dirt that the fricative powder of dust, aqueous vapor, contact chip and contact point (resistance substrate) interacts and produced in the inner use of these switches at present, these materials can increase the unnecessary electrical impedance in the circuit; Can make circuit produce fault even circuit interruption when serious; Moreover existing switch is many because of part, and assembling is inconvenience very; Increase the number of assembling steps of production line, improved production cost; Moreover existing band switch can't be adjusted the mechanism of torsion, this shows, the above-mentioned article of commonly using still have many disappearances, real non-one kindhearted design, and demand urgently improveing.

This case inventor commonly uses the drawbacks that band switch is derived in view of above-mentioned, is urgently to think to improve innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, finally successful this part of research and development completion band switch.

Summary of the invention

The object of the invention promptly is to provide a kind of band switch, and this switch is via the attracting each other of magnetic force, to reach the simplification of manufacturing when rotated.

An of the present invention purpose is to be to provide the increase and decrease adjustment of a kind of torsion of band switch via magnetic quantity, rotates the band switch that torsion can change with adjustment.

Can reach the band switch of foregoing invention purpose, include:

One main body has holding area, in its holding area around the circular row body that is magnetic;

One rotating part is to be assembled in the holding area of main body, wears axle with one on this rotating part and is located in main body, and its side has a magnetic (or metallic object) at least, and the bottom surface is installed with contact chip;

One bottom, in order to cover the holding area of main body, the one of which side comprises that at least one electronic component can directly or indirectly contact with the contact chip of rotating part, and this electronic component is provided with the resistive element of different coefficients.

Band switch of the present invention changes the principle of friction-driven between main body, rotating part and bottom, controls the size of rotating torsion with the mode of magnetic attraction, thereby reach contactless fine setting output is provided, and reduces contact chip and the fricative dirt of contact point.

Embodiment

See also Fig. 1 and Fig. 2, band switch provided by the present invention is the band switch of function such as be used for light modulation, regulate the speed, and mainly includes: a main body 1, a rotating part 2 and a bottom 3.

This main body 1 has holding area 11, and these holding area 11 interior ring-type equidistance on every side are arranged with magnetic 12, and this magnetic 12 is magnet, permanent magnet, electromagnet or solenoid (magnet coil);

This rotating part 2 is to be assembled in the holding area 11 of main body 1; Wear axle 21 with one on this rotating part 2 and be located in main body 1, its side has a magnetic 22 (or metallic object) at least, and the bottom surface is installed with contact chip 23; This contact chip 23 is constituted by metal material, so that the function of turning circuit to be provided; It is characterized in that said magnetic 22 is magnet, permanent magnet, electromagnet or solenoid, and this metallic object is metals such as iron, cobalt, nickel; The variation of these magnetic 22 quantity can increase or reduce the torque magnitude when rotating;

The holding area 11 of this bottom 3 in order to cover main body 1; Can be provided with water proof rubber again between the contact-making surface of this bottom 3 and main body 1; To prevent that water gas from getting in the main body 1; Bottom of the present invention 3 one of which sides comprise that at least one electronic component 31 can directly or indirectly contact with the contact chip 23 of rotating part 2, and this electronic component 31 is provided with the resistive element of different coefficients; This electronic component 31 is to be arranged at the side that contacts with accommodation space; Be applied as electronic component 31 annular arrangements on bottom 3 of the present invention; And be positioned on the rotation path of contact chip 23 of rotating part 2, can contact with at least one electronic component 31 when providing contact chip 23 to rotate.

Please consult Fig. 3 and Fig. 4 again; Band switch of the present invention can be set up a knob 4 in the axle 21 of wearing of rotating part 2 again when operation; To make things convenient for user regulate the speed speed or bright and dark light, when knob 4 was rotated, the magnetic 22 (or metallic object) on the rotating part 2 can attract with annular magnetic 12 in main body 1 its holding area 11 mutually; And can provide knob 4 to finely tune the function of angles; 23 of the contact chips of these rotating part 2 bottom surfaces can be because of the fine setting of knob 4, and contact chip 23 electronic component 31 with on the bottom 3 is in regular turn contacted, because of the resistance coefficients of 23 corresponding contacts of contact chip different; So can utilize the different different electric currents of resistance coefficient output, to reach the purpose of adjustment.
