Abstract
The utility model relates to a microswitch which comprises a shell, a metal inserted pin I and a metal inserted pin II. The metal inserted pin I and the metal inserted pin II are respectively inserted on a side surface of the shell; the microswitch further comprises a switching mechanism; the switching mechanism comprises a button, a spring leaf I and a spring leaf II; one end of the spring leaf I is connected with the metal inserted pin I in a contact way; the other end of the spring leaf I is crosswise connected with one end of the spring leaf II; the other end of the spring leaf II is connected with the metal inserted pin II in a contact way; a middle section of the spring leaf I is provided with an elastic leaf; the elastic leaf is clamped in a clamping groove at a bent position of the metal inserted pin II; the button is pressed above the joint between the spring leaf I and the spring leaf II; and a head is protruded on the surface of the shell. Compared with the prior art, the microswitch has the advantages of simple product structure, convenience, durability, strong conductivity performance and long service life.
Description
Technical field
The utility model relates to appliance switch, relates in particular to sensitive switch.
Background technology
Switch is in order to the visual plant of control apparatus device in people's daily life or the industrial production, no matter be electric light, household electricity device indispensable during people live, or in industrial production important large scale industry mechanical electric apparatus, all need to be controlled by switch.
The kind of switch is a lot, and sensitive switch is a wherein important class.Common sensitive switch is made up of switch case and the button that is arranged on the switch case, and button can be delivered to the inner associated components of switch case with power or the stroke from the outside.But at present in the sensitive switch on the market, product structure is simple, convenient durable, be active in one's movements, and electric conductivity is powerful, the big electric current of conducting that can be stable, long service life comparatively rare.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the defective that above-mentioned prior art exists, and a kind of sensitive switch of simple in structure, long service life is provided.
The purpose of this utility model can be achieved through the following technical solutions: sensitive switch, comprise shell, the metal pin I, the metal pin II, described metal pin I, the metal pin II is plugged in the side surface of shell respectively, it is characterized in that, also comprise switching mechanism, described switching mechanism comprises button, the spring leaf I, the spring leaf II, described spring leaf I one end is connected with the contact of metal pin I, one end interconnection of the described spring leaf I other end and spring leaf II, the other end of described spring leaf II is connected with the contact of metal pin II, the stage casing of described spring leaf I is provided with shell fragment, this shell fragment is fastened in the draw-in groove of bending place of metal pin II, described button is pressed on the top, junction of spring leaf I and spring leaf II, and head is raised in case surface.
Described spring leaf I one end is provided with the contact.
The contact position of described metal pin I and spring leaf I one end is provided with the contact.
Also comprise the metal pin III, described metal pin III is located at the below of metal pin I.
Described spring leaf I is formed by stacking by two shell fragments.
Compared with prior art, advantage of the present utility model comprises: product structure is simple, convenient durable, and electric conductivity is powerful, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model sensitive switch.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
As shown in Figure 1, sensitive switch, comprise shell 1, metal pin I 3, metal pin II5, described metal pin I 3, metal pin II 5 is plugged in the side surface of shell 1 respectively, also comprise switching mechanism, described sudden strain of a muscle disconnects closing and comprises button 2, spring leaf I 7, spring leaf II 8, described spring leaf I 7 one ends are connected with metal pin I 3 contacts, the end interconnection of described spring leaf I 7 other ends and spring leaf II 8, the other end of described spring leaf II 8 is connected with metal pin II 5 contacts, described spring leaf I 7 stage casings are provided with shell fragment, this shell fragment is fastened on metal pin II5 bending place, described button 2 is pressed on the top, junction of spring leaf I 7 and spring leaf II 8, and head is raised in shell 1 surface.Described spring leaf I 7 one ends are provided with the contact.Described metal pin I 3 is provided with the contact with the contact position of spring leaf I 7 one ends.Described spring leaf I is formed by stacking by two shell fragments.
When button was pressed, spring leaf I 7, spring leaf II 8 pressed down, and spring leaf I 7 is according to lever principle, and that end that contacts with metal pin I 3 bends downwards, finishes the switch task.
Fixing hole 6 is in order to fix this product.Metal pin III4 is in order to limit the motion lower edge of spring leaf I 7.When pressing the button and can contact, with the contact separation of the metal pin I 3 of upper end with metal pin III4 to certain stroke.
Claims (5)
