Abstract
The utility model discloses a magnetic switch, which comprises a box body and a box cover, wherein the box body is provided with a cavity; a support is arranged in the cavity of the box body; a staticcontact is arranged on the support; a chute is arranged on the support; a first magnet is slidingly fitted in the chute; one end of the first magnet is provided with a reset spring; the other end ofthe reset spring is fixedly connected on the chute wall surface of the support; a movable contact is arranged on the first magnet; the movable contact and the static contact are normally closed; a second magnet is arranged on the box cover; and the magnetism of the magnetic pole of the second magnet opposite to the first magnet is the same. The magnetic switch has safety and reliability and convenient use, also has the advantages of simple structure.
Description
Technical field
The utility model relates to a kind of small circuit switch, particularly relates to a kind of magnetic switch.
Background technology
The construction of switch of present mobile computer, generally be to be installed on the housing of its LCD screen, by by the pressing key that is pressed on the LCD screen hull outside, drive a pair of trip that exposes on the screen housing, on the host shell of mobile computer, spin off in the set groove, allow the user can raise its screen housing.Because trip exposes to outside the housing, under permanent, frequent situation about using, trip causes damage easily or follows the string, can't withdraw, and causes the inconvenience in the use.
Summary of the invention
The purpose of this utility model provides a kind of magnetic switch safe and reliable and easy to use, simultaneously, the utlity model has advantage of simple structure.
The technical scheme that realizes the utility model purpose is as follows:
Magnetic switch, comprise box body, lid with cavity, be provided with bearing in the cavity of box body, bearing is provided with fixed contact, described bearing is provided with chute, one first magnet is snug fit in the chute, first magnet, one end is provided with back-moving spring, the back-moving spring other end is fixedly connected on the chute wall of bearing, first magnet is provided with moving contact, moving contact and fixed contact are closure state under the normality, and one second magnet is arranged on the lid, and the magnetic of the magnetic pole that this second magnet is relative with first magnet is identical.
Described lid is provided with chute, and second magnet is snug fit in this chute.
Be provided with limiting component in the chute of described lid.
Adopted such scheme, described bearing is provided with chute, first magnet, one end is provided with back-moving spring, the back-moving spring other end is fixedly connected on the chute wall of bearing, first magnet is provided with moving contact, moving contact and fixed contact are closure state under the normality, thus switch when being normality circuit be on-state.One second magnet is arranged on the lid, and the magnetic of the magnetic pole that this second magnet is relative with first magnet is identical.During use, move second magnet, make second magnet relative with first magnet to the service position, because second magnet is identical with the polarity of first magnet, therefore second magnet and first magnet repel mutually, and first magnet drives the moving contact motion, moving contact separates with fixed contact, and circuit disconnects.Reach the purpose of control circuit conducting and disconnection by the switch of said structure, not only easy to use, and need not form with conductive component in the use and contact, can improve the fail safe of operation.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model.
In the accompanying drawing, 1 is box body, and 2 is lid, and 3 is moving contact, and 4 is fixed contact, and 5 is back-moving spring, and 6 is first magnet, and 7 is bearing, and 8 is second magnet, limiting component 9.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, be magnetic switch of the present utility model, comprise box body 1 with cavity, lid 2, be provided with bearing 7 in the cavity of box 1 body, bearing is provided with fixed contact 4, described bearing is provided with chute, one first magnet 6 is snug fit in the chute, first magnet, 6 one ends are provided with back-moving spring 5, back-moving spring 5 other ends are fixedly connected on the chute wall of bearing, and first magnet 6 is provided with moving contact 3, and moving contact 3 is a closure state with fixed contact 4 under the normality, one second magnet 8 is arranged on the lid, and the magnetic of the magnetic pole that this second magnet is relative with first magnet is identical.Lid is provided with chute, and second magnet is snug fit in this chute.Be provided with limiting component 9 in the chute of described lid.
