CN2247864Y - Three-stage mains switch with built-in diode - Google Patents

Abstract

The utility model discloses a structure of a three-stage mains switch with a built-in diode. The utility model is characterized in that a rotor is divided into three stages of arcs, wherein the first arc and the second arc are enclosed by the same metal sheet, and the third arc is an edge of the rotor. The structure is used for causing the light to generate a reasonable process from semi-brightness to extinguishment. Because a diode is stored in a switch casing through the utility model, the utility model has the advantages of beautiful appearance, practicality and safe use.

Description

The three stage power source switch of built-in diode

The utility model relates to the three stage power source switch of the improvement, particularly a kind of built-in diode of the power switch structure that daily life uses.

Present advanced person in the world adjusts electric current with diode, makes light change the level Four mains switch of brightness, makes four processes such as light bright through associating-half become clear-become clear-extinguishes, and its shortcoming is: light is partly bright from becoming clear, the physilogical characteristics of incompatibility human eye; The bright process of secondary is arranged, and is unnecessary repetition; The diode of adjusting electric current is in the outside of level Four mains switch, uses dangerously, designs unreasonable.

The purpose of this utility model is at above-mentioned shortcoming, develop a kind of three stage power source switch of built-in diode, make light become clear-become clear-extinguish three processes through more than half, the physilogical characteristics that more adapt to human eye, reduced once and repeated, because it is diode is installed in three stage power source switch case inside, therefore reasonable in design, safe in utilization.

The purpose of this utility model is achieved in that a level Four rotor changes three grades of rotors into, wherein connects with the output wire ends again after article one circular arc and the diode UNICOM; The second circular arc is connected input wire ends and output wire ends; Article three, circular arc is an insulator, can make input wire ends and output wire ends insulation, simultaneously diode is installed in three stage power source switch case inside, makes that product is attractive in appearance, practical, safety.

The utility model is owing to adopt above improvement project, solve the level Four mains switch effectively and repeated to make the bright no active state once of light, and make light partly bright to becoming clear to the reasonable process of closing through associating, particularly diode is ensconced three stage power source switch case inside, and the user can use safely.

Structure of the present utility model can be referring to accompanying drawing 1, accompanying drawing 2 and embodiment:

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is three grades of rotor structure schematic diagrames of the utility model.

Three grades of rotors 3 are installed at middle part at the housing 5 of three stage power source switch, three grades of rotors 3 are insulators, are with the limit of three circular arcs outward, in these three circular arcs, article one, circular arc 11 and second circular arc 12 are to be surrounded by same sheet metal, and the 3rd circular arc 13 is limits of the insulator of three grades of rotors 3.When the conducting strip 6 of input electric wire 1 contacts with article one circular arc 11, when the conducting strip 7 of output electric wire 2 contacts with the 3rd circular arc 13 of insulation just, after electric current enters diode 4 by the conducting strip 6 of input electric wire 1, through second circular arc 12 and diode conduction sheet 8, flowing into output electric wire 2 through conducting strip 9, at this moment electric light sends half bright lamplight under the diode rectification effect.When rotating three grades of rotor 3 by hand, the conducting strip 6 of input electric wire 1 contacts with second circular arc 12, and the conducting strip 7 of exporting electric wire 2 simultaneously contacts with article one circular arc 11, and electric current leads directly to and mistake, at this moment the electric light brightness that emits a brilliant light.When reversing three grades of rotor 3 again, the conducting strip 6 of input electric wire 1 contacts with the 3rd circular arc 13 of insulation, and this moment, electric current was cut off, and electric light extinguishes.Turn on light if desired, turned round three grades of rotor 3 more just, so go round and begin again.

Claims (1)

1, a kind of three stage power source switch of the built-in diode of forming by casing, rotor, diode, input and output electric wire, it is characterized in that above-mentioned rotor is three grades of rotors 3, three grades of rotors 3 are insulators, be with the limit of three circular arcs outward, wherein article one circular arc 11 and second circular arc 12 are to be surrounded by same sheet metal, article three, circular arc 13 is limits of the insulator of three grades of rotors 3, and above-mentioned diode 4 is installed in three stage power source switch case 5 inside.
