Problems solved by technology

[0003] Disadvantages of using mechanical coding switches: due to the need to open holes in the electrical equipment, the integrity of the electrical equipment shell is destroyed, and it will also affect the strength of the shell, and have a negative impact on the sealing performance of the electrical equipment. As a result, the requirements for waterproof, moisture-proof and leakage prevention cannot be met

Embodiment Construction

[0019] As shown in FIG. 2, an inductive coding switch includes an inductive switch plate 200 and an inductive knob 202. The inductive switch plate 200 and the inductive knob 202 are placed on both sides of an operation panel 204 (the operation panel here is a glass panel), And by the mutual attraction of the first permanent magnet CL in the center of the induction switch plate 200 and the second permanent magnet CH in the center of the induction knob 202, the induction switch plate 200 includes n ( n>=3) Hall switches 210, the induction knob 202 includes a base 208 for fixing the second permanent magnet, a knob 206 mounted on the base 208, and a knob 206 evenly distributed on the same circumference of the inner shell of the knob m (m is an even number) permanent magnets, and by rotating the knob 206, a magnetic field that changes relative to the induction switch plate 200 is generated.

[0020] In order to ensure that two or more Hall switches 210 do not turn off to on at the ...

Abstract

The inductive addressable switch includes inductive switchboard and inductive knob. Being positioned on two side of the operation panel, the switchboard and knob are located by attractive interaction between first permanent magnet at center of the inductive switchboard and second permanent magnet at center of the inductive knob. The inductive switchboard includes n (larger than or equal to 3) pieces Hall switches distributed on same circumference evenly. The inductive knob includes base in use for fixing up second permanent magnet, knob instilled in the base, and m (even number) pieces of permanent magnet distributed on same circumference of inner casing of knob evenly. Rotating the knob generates magnetic field variational to the inductive switchboard. The invention does not need to make hole on body case of electrical installation so as to keep integrality of installation, and reach purpose of moistureproof and anticreep.

Description

technical field [0001] The present invention relates to a switch, more particularly, to an inductive coded switch. Background technique [0002] The existing mechanical coding switch (as shown in FIG. 1 ) includes a coding switch shaft 102, a knob 104, a fixing nut 106, an electrical equipment housing (or operation panel) 108, a through hole 110 on the housing, and a mechanical coding switch. The main body 100 and the pin 112 of the internal mechanical switch need to open holes on the electrical equipment shell during use, so that the encoder switch shaft 102 extends out of the operation panel 108 of the electrical equipment through the through hole 110 on the shell 108. A knob 104 is installed on the rotating shaft 102 . [0003] Disadvantages of using mechanical coding switches: due to the need to open holes on electrical equipment, the integrity of the electrical equipment casing is destroyed, and the strength of the casing will also be affected, and the sealing performa...
