Problems solved by technology

[0002] Ordinary micro switches include a shell and a button protruding from the shell. There is a protrusion on one side of the button, and the protrusions on one or both sides of the micro switch are added to play a supporting and guiding role. This structure allows the touch piece to directly touch To the button, and then produce an action, but the button as a direct touch, easy to wear and damage, shorten the service life, and frequent touch, resulting in damage to the shrapnel

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] like figure 1 As shown, an improved micro switch of the present invention includes a housing 1, a button 2 passing through the housing 1 and a connecting contact. The upper end of the housing 1 is provided with a shrapnel 3, and the shrapnel 3 presses the button 2 and Inclined above the housing 1, the lower end of the shrapnel 3 extends into the housing 1, the lower end of the shrapnel 3 is in contact with the movable piece 4, the upper part of the movable piece 4 is in contact with the bottom of the button 2, and the lower part of the movable piece 4 is connected with the push rod 5. The end of the movable piece 4 is provided with a conversion contact piece, which is used to contact the connecting contact, and the connecting contact includes a normally closed contact 6 and a normally open contact 7 .

Abstract

The invention discloses an improved microswitch. The improved microswitch comprises a shell, a button and a connection contact, wherein the button penetrates through the shell. An elastic sheet is arranged at one end of the upper portion of the shell. The elastic sheet presses the button and is arranged above the shell in an inclined mode. The lower end of the elastic sheet extends into the shell and is in contact with a movable sheet. The upper portion of the movable sheet is in contact with the bottom of the button and the lower portion of the movable sheet is connected with a push rod. The tail end of the movable sheet is provided with a conversion contact part. The conversion contact part is used for making contact with the connection contact. The connection contact comprises a normally closed contact and a normally open contact. According to the improved microswitch, when a user touches the elastic sheet, the button moves downwards, the movable sheet below the button is extruded through the button, the conversion contact part changes, an upper hinge shaft makes contact with the normally closed contact, and a lower hinge shaft is far away from the normally open contact through a pull rod and the push rod. The user touches the button indirectly by touching the elastic sheet, a spring is additionally arranged, and therefore the reset capacity is stronger, the button can be connected and disconnected frequently, the structure is simple, and the service life is long.

Description

technical field [0001] The invention relates to a micro switch, in particular to an improved micro switch. Background technique [0002] Ordinary micro switch, including the shell and the button protruding from the shell, has a protrusion on one side of the button, and the protrusion on one or both sides of the micro switch is added to play a supporting and guiding role. This structure makes the touch piece directly touch Touch the button, and then produce an action, but the button, as a direct toucher, is easy to wear and damage, the service life is shortened, and frequent touches cause the shrapnel to be damaged. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a micro switch with simple structure and quick turn-on and turn-off. [0004] Technical scheme provided by the invention: [0005] An improved micro switch, includin...
