Abstract

The utility model relates to a push-button type magnetic switch. The push-button type magnetic switch is composed of a shell body, a wiring terminal provided on the shell body, a button and a moving contact head reed, which is driven by the button. Both contact points of the moving contact head reed are driven by the button and are movably connected with the fixed contact head of the wiring terminal. Magnets which are opposite in polarity are respectively assembled on the fixed contact heads of the moving contact head reed and the wiring terminal. Because the space of switch contact heads adopts the magnets which magnetize each other, the method enlarges the switching force of the switch opening process and realizes the fast switching of the switch, effectively preventing the occurrence of electric spark in the switch conversion process. More importantly, moving contact points and fixed contact points can ensure a close contact operating state and thoroughly solve the phenomenon occurrence of the moving contact point and the fixed contact point because of arc spark sintering, and consequently the utility model effectively provides a stable and reliable power supply mode for lines and controlled objects. Simultaneously, the switch also has the advantages of simple integrated structure, long service life, convenient application, stable working and high reliability, etc.

Description

The push button magnetic switch

Technical field

The utility model relates to a kind of appliance switch that is used for the control circuit break-make, a kind of specifically push button magnetic switch.

Background technology

The appliance switch that is used for the control circuit break-make at present mostly is made up of housing and binding post, button, spring and moving contact reed and the interlinked mechanism be located on the housing, described moving contact reed under the effect of button and spring with the function that contact is finished closure or disconnection of deciding of binding post, to realize control to controlled device.The appliance switch of this kind structure is the following fault of anxious easily generation after the use repeatedly of long period: the first is owing to the switching of switch is mainly finished by button compression spring, long-term use, the elasticity of its spring is aging, make the Kai Heguan of switch not put in place effectively, the virtual connection phenomenon appears in circuit, causes the impedance of circuit to increase, circuit heats up, break down thereby cause circuit or controlled device, spring can not reset when serious, causes switch out of control.It two is that interlinked mechanism uses for a long time and anxious easily produce wearing and tearing and damage, and makes switch cisco unity malfunction or damage.Owing to above-mentioned fault, the switch of this kind structure is short useful life in a word, and the failure rate height has brought unnecessary inconvenience or loss to the user.

Summary of the invention

The purpose of this utility model is to provide and contacts between a kind of contact closely, failure rate is low, the push button magnetic switch of long service life.

The purpose of this utility model is achieved in that this push button magnetic switch is by housing be located at binding post on the housing, button and be made up of the moving contact reed that button drives, two terminal contacts of its moving contact reed flexibly connect with the contact of deciding of binding post under the driving of button, and the deciding of two terminal contacts of said moving contact reed or binding post is equipped with magnet on the contact.

The technological progress that the utility model is obtained is: owing to adopt the magnet that attracts each other between switch contact, not only strengthened the switching power of switch open process, realized the quick switching of switch, prevented the generation of electric spark in the switch transition process effectively.The more important thing is between moving contact and fixed contact and can guarantee a kind of tight operating state that contacts, thoroughly solve moving contact and fixed contact because the generation of arc spark sintering phenomenon, thereby can be effectively provide a kind of reliable and stable supply power mode for circuit and controlled device.This switch has also that overall structure is simple simultaneously, long service life, application is convenient and characteristics such as work stability and reliability height.

Description of drawings

Fig. 1 is the structural representation of first kind of execution mode of the utility model.

Fig. 2 is the structural representation of second kind of execution mode of the utility model.

Embodiment

Be that embodiment further specifies the utility model below with the accompanying drawing: this push button magnetic switch is by housing and be located at binding post on the housing, button and be made up of the moving contact reed that button drives, the deciding of two terminal contacts of described moving contact reed or binding post is equipped with magnet on the contact, have at the driving lower moving contact reed two ends of button magnet the contact can and the binding post switching function of deciding to finish between contact switch.

Fig. 1 is a kind of execution mode of the present utility model, as can be seen from the figure, this execution mode is a kind of button magnetic switch that is used on the body of wall, the outer surface of its housing 1 is a square structure, manually button 2 is located on the outer surface of housing 1, on the medial surface of manual button 2, be provided with two bayonet locks with its one, two bayonet locks are installed on to be located in the groove of stirring bayonet lock 3 both sides, it is stirred 1 bearing pin of bayonet lock 3 and housing and is connected, and the bottom of stirring bayonet lock 3 is equipped with the bearing pin that matches with moving contact reed 4 upper shift forks 5.Moving contact reed 4 is domes, and it is one that moving contact reed 4 is decided contact 6 clampings with the binding post of being located at the housing middle part, and promptly the bayonet socket on the moving contact reed 4 is installed on and is located at binding post and decides in the card on the contact 6.Shift fork 5 is located on the medial surface of corresponding bayonet socket place moving contact reed 4, and the draw-in groove on its shift fork 5 tops is installed on to be located in the bearing pin of stirring bayonet lock 3 bottoms.In the housing 1 of corresponding moving contact reed 4, be provided with three binding posts and decide contact 6, the binding post of its both sides is decided to be respectively equipped with on the contact 6 and the opposite magnet 7 of moving contact reed 4 two ends upper magnets 7 magnetic, also can be equipped with magnet 7 on binding post is decided any contact of contact 6 or moving contact reed 4 two ends contacts, its another corresponding contact selects for use metal material to get final product.The indirect terminal is decided contact 6 and is connected with moving contact reed 4.When this magnetic switch used, the operator in the interaction that overcomes magnetic force between two contacts, can make pair of contact open by pushing manual button 2, and another contacts the contact, has promptly realized the switching function of switch.

Fig. 2 is another execution mode of the present utility model, as shown in the figure, this kind execution mode and above-mentioned difference are that moving contact reed 4 is packed on the medial surface of button 2, its moving contact reed 4 and button 2 are assemblied in the middle part binding post by same bearing pin 8 to be decided to constitute a see-saw structure on the contact 6.Also moving contact reed 4 and button 2 can be assemblied in binding post by same bearing pin and decide on the contact 6, its moving contact reed 4 is made domes, and is respectively equipped with push rod on the two side arms of button 2 corresponding moving contact reeds 4.During work again push rod promote the two side arms of contact reed 4, can finish the switching function of switch.Above-mentioned said moving contact reed 4 and button 2 also can be assemblied on the housing 1 by same bearing pin 8, and the contact of the middle part binding post being decided contact 6 is connected with moving contact reed 4 and gets final product.
