Abstract

An automatic return switch refers to an electrical appliance frequency modulation switch with automatic return function. The structure comprises an axle core (1); an axle (11) integrally connecting with the axle core (1) and passing through a support (2), an axle bushing (3), a rotor (5) and a poking plate (7) in sequence; and a body (10) arranged below the axle bushing (3). The utility model is characterized in that the rotor (5) and the poking plate (7) are movably nested in the axle bushing (3); an internally covering torsion spring (6) and an externally arranged electric contact piece are respectively on two surfaces of the poking plate (7); the body (10) covers internally a pot piece (9); the body (10) is respectively provided with a metal piece (103), a contact brush claw (102) and a terminal (101).

Description

A kind of automatic reset switch

Technical field

The utility model relates to a kind of electrical equipment frequency modulation switch, especially a kind of can automatically reset electrical equipment frequency modulation switch.

Background technology

At present, after conventional switch is pressed or twisted, can remain on the state that opens or closes, can not automatically reset, this brings great inconvenience to the user.Needing in being permitted technology member such as electrical equipment can automatically reset switch, and requires this switch highly sensitive, reliable, the long service life of switch, safety technically.

The utility model content

The utility model is at above-mentioned the deficiencies in the prior art, is intended to release that a kind of energy is automatically reset and highly sensitive, reliable, the switch of long service life, safety.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of automatic reset switch, comprise a core in the structure, pass support, axle sleeve, rotor successively and stir dish with the whole axle that is connected of axle core, below axle sleeve, be provided with body, movable fit rotor and stir dish in the axle sleeve, stir interior respectively button torsion spring in dish two sides and peripheral hardware electric contact piece, the young sheet of button pot is respectively equipped with sheet metal, contact brush pawl and terminal in the body on the body.

The beneficial effect of a kind of automatic reset switch of the utility model is: simple in structure, easy to use, can automatically reset.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is a decomposing schematic representation of the present utility model.

The drawing reference numeral explanation:

1, axle core 2, support 3, axle sleeve

4, collar 5, rotor 6, torsion spring

7, stir dish 8, lesser trochanter 9, the young sheet of pot

10, body 101, terminal 102, contact brush pawl

Embodiment

Referring to figs. 1 through Fig. 2, the utility model is to implement like this:

A kind of automatic reset switch, comprise a core (1) in the structure, pass support (2), axle sleeve (3), rotor (5) successively and stir dish (7) with the whole axle (11) that is connected of axle core (1), be provided with body (10) in axle sleeve (3) below, it is characterized in that: movable fit rotor (5) and stir dish (7) in the axle sleeve (3), stir interior respectively button torsion spring (6) in dish (7) two sides and peripheral hardware electric contact piece, button pot young sheet (9) is respectively equipped with sheet metal (103), contact brush pawl (102) and terminal (101) in the body (10) on the body (10).

Axle (11) cutting ferrule collar (4) in a kind of automatic reset switch of the present utility model, movable sleeve sympodium cover (3), axle (11) is fit lesser trochanter (8) fixedly, and axle (11) is lesser trochanter (8) downslide synchronously thereupon on time downwards.

A kind of automatic reset switch of the present utility model, passing axle sleeve (3) with the whole axle (11) that is connected of axle core (1) interlocks with rotor (5), rotor (5) snaps together with the dish (7) of stirring of interior button reduction torsion spring (6), axle core (1) downwards by and when stirring simultaneously, the lesser trochanter (8) that is with insulating material presses down synchronously thereupon and makes the young sheet of sphere shape pot (9) bounce-back, the bounce-back of pot young sheet (9) convex surface inwards with body (10) in sheet metal (103) thus contact connections, a pot young sheet (9) the previous position of rebounding go back to after pressing no longer down; Axle core (1) is when stirring simultaneously, rotor (5), reduction torsion spring (6) and stir dish (7) and rotate synchronously thereupon, stirring dish (7) goes up electric contact piece and contacts with contact brush pawl (102) on the body (10) and send signal, reduction torsion spring (6) both sides of stirring on the dish (7) are limited by the both sides strong point in the axle sleeve, stir when moving reduction torsion spring (6) on one side supported point be limited in original position, the other end then rotates tension force of formation with stirring dish (7), stop to stir the back and stir dish (7) be returned to position stirring before under the effect of tension force, a corresponding core (1) also returns to stirs preceding position.

A kind of automatic reset switch of the present utility model, body (10) are gone up and fixedly are buckled with bonnet (12).

The above, it only is the preferred embodiment of a kind of automatic reset switch of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model above any trickle modification, equivalent variations and modification that embodiment did.
