Abstract

The utility model relates to a double-pole switch for small electrical appliances, comprising make-and-break switching devices which comprise a bottom shell, a swinging cap and active and stationary contacts, wherein, the stationary contact is fixed on the contact foot of the bottom shell, the active contact corresponding to the stationary contact is fixed on the end part of the springboard, a spring and a steel ball are respectively arranged in two symmetrical cylinder-shaped pipes positioned on the lower part of the swinging cap, and are respectively pressed with the springboard rotating using the connection wire sheet as the pivot, making two groups of active and stationary contacts, and two contact feet and two support feet form two groups of make-and-break switching devices; the neon lamp reclines on the neon lamp seat on the lower part of the swinging cap, and is parallelly connected with two support feet after being connected in serials with the resistor; the swinging cap is made of non-light tight materials or a non-light tight lampshade is arranged on the swinging cap, in order to display the make-and-break of the electric appliance circuit. The utility model, because of having two groups of make-and-break switching devices, can simultaneously control the make-and-break of the circuit live wire and zero line, thereby avoiding the kickbacks of getting an electric shock resulted from the mistaken connecting of the switch , etc. and ensuring the human safety.

Description

The compact electric apparatus double-pole switch

Technical field

The utility model relates to a kind of compact electric apparatus switch, especially a kind of double-pole switch of compact electric apparatus.

Background technology

The compact electric apparatus switch that uses all passes through the branch of one group of dynamic and static contact, the switching of incompatible control live wire usually at present.The patent No. be " 01238463.1 ", " a kind of microminiature Illuminated Switch " it comprise housing, Bai Gai, neon lamp, moving contact and fixed contact, fixed contact is fixed on the contact feet of housing, this contact feet is connected with live wire, switch is used for controlling the switching of live wire.Neon lamp is bright, and display circuit is connected; Neon lamp goes out, and display circuit disconnects.In practical operation, because work carelessness, easily with the appliance switch reversal connection on circuit, so just cause contact feet to be connected with zero line, switch just is used for controlling the switching of zero line, bright, the only switching of display circuit of going out of neon lamp, and live wire still is in on-state with electrical equipment always, electrical equipment is charged all the time, can cause great threat to personal safety like this.

Summary of the invention

The purpose of this utility model is at the defective of prior art and deficiency, for electrical apparatus industry provides a kind of small capacity double knife switch that can control live wire and zero line break-make simultaneously.The utility model comprises the break-make switching device shifter that drain pan, pendulum lid and dynamic and static contact are formed, fixed contact is fixed on the contact pin of drain pan, be fixed on the end of springboard with the corresponding moving contact of fixed contact, two symmetrical cylindrical tube that are positioned at pendulum lid below are equipped with spring, steel ball respectively, and compress mutually with the springboard that with the lug plate is the fulcrum rotation respectively, make two groups of dynamic and static contacts and two contact pin and two stent foots form two groups of break-make switching device shifters; The neon lamp accumbency on the neon lamp seat below the pendulum lid, and be connected on two stent foots after resistance is connected in series; Pendulum lid is made or is put to cover by light transmissive material a transparent lamp shade is installed, and shows that neon lamp is bright or does not work.The utility model is owing to adopt two groups of break-make switching device shifters, and the switching of live wire and zero line on the control apparatus has simultaneously been avoided switch connection error and caused adverse consequences such as electric shock, has guaranteed personal safety.The utility model volume is little, assembling is easy, cost is low, for the appliance switch industry provides a kind of new varieties again.

Embodiment

As shown in the figure, at the contact of the utility model drain pan 1 pin 10,10 ' on be fixed with fixed contact 12 respectively, 12 ', with fixed contact 12,12 ' corresponding moving contact 11,11 ' be fixed on springboard 8,8 ' on, springboard 8,8 ' respectively with stent foot 7,7 ' on lug plate 13,13 ' be that fulcrum rotates, the neon lamp seat 6 that pendulum covers 2 belows covered for 2 fastened to each other connections with pendulum, the cylindrical tube of two symmetries and neon lamp seat fuse, be with respectively in the pipe spring 5 and spring 5 ', spring 5, the steel ball 9 of 5 ' below, 9 ' respectively with springboard 8,8 ' compress mutually, cover 2 open by pendulum, close, make steel ball 9,9 ' under the elastic reaction of spring at springboard 8,8 ' go up left, the right slip, thereby drive moving contact 11,11 ' with the fixed contact 12 of below, 12 ' closed or disengaging makes live wire and zero line while on-off on the electrical equipment.For the energising that shows electrical equipment whether, neon lamp 3 is housed in neon lamp seat 6, its two ends, neon lamp 3 series resistors, 4 back be attempted by respectively stent foot 7,7 ' on.

During use, press bottom lid, steel ball 9,9 ' left slides, make be fixed on springboard 8,8 ' on moving contact 11,11 ' respectively and contact pin 10,10 ' on fixed contact 12,12 ' closure, thereby by springboard 8,8 ' and lug plate 13,13 ', when the contact pin 10 that is connected with live wire and stent foot 7 are connected, the contact pin 10 that is connected with zero line ' with stent foot 7 ' also connection, at this moment, neon lamp is bright.Pendulum Gai Ruo is made by light transmissive material, and whole pendulum lid is shinny, shows the electrical equipment energising.If the pendulum lid is made by light-proof material, cover at pendulum a lampshade 14 is housed on 2, when neon lamp was bright, lampshade was shinny, to show the electrical equipment energising.Otherwise dynamic and static contact breaks away from, and live wire and zero line on the electrical equipment disconnect simultaneously, and neon lamp does not work, and promptly the lampshade that pendulum covers or pendulum covers does not work.The utility model is owing to adopt two groups of break-make switching device shifters, and the live wire on the control apparatus and the break-make of zero line have simultaneously been avoided switch connection error and caused adverse consequences such as electric shock, have guaranteed personal safety.The utility model is rational in infrastructure, and properties of product are good.
