Description

Technical Field

[0001] The utility model relates to the technical field of magnetic switches, in particular to a magnetic switch contact key structure. Background Art

[0002] The magnetic switch uses a magnetic component to attract a metal sheet, and presses the metal sheet to make it touch the lower power contact or detach from the upper power contact to achieve the effect of opening or closing the circuit. Compared with traditional spring switches, magnetic switches do not have the life problem of metal fatigue and have a longer service life.

[0003] At present, when the magnetic switch contact button is pressed down, the cover plate and the button of the contact switch have a strong rebound action, which causes the magnetic switch contact button to make a loud noise when in use. The excessively loud use noise of the magnetic switch contact button will bring noise trouble to the user at night, thereby affecting the working mentality of the user of the magnetic switch contact button. For this reason, we propose a magnetic switch contact button structure. Utility Model Content

[0004] The main purpose of the utility model is to provide a magnetic switch contact button structure, in which a buffering button structure is arranged between a magnetic switch shell equipped with an inner contact and a pressure cover. When the pressure cover is pressed against the inner contact in the magnetic switch shell, a transfer plate, an angle pad, a gasket A and a gasket B are used for buffering during the initial pressing, and the inner sunken pad and the inner sunken disk form a secondary buffering structure when the pressure cover continues to be pressed down, which buffers the pressure-touch noise of the pressure cover and the magnetic switch shell, and the inner contact can be buffered when it is pressed by the hard rubber plate, thereby effectively reducing the noise when the magnetic switch contact button is pressed, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A magnetic switch contact key structure comprises a magnetic switch shell, an inner contact and a pressure cover, and also comprises a transfer plate, a hard rubber plate, a corner pad, an inner sunken pad, a washer A, a washer B and an inner sunken disk. The inner contact is centrally installed in the shell of the magnetic switch shell, and the transfer plate and the pressure cover are sequentially pressed into the magnetic switch shell above the inner contact. A middle opening is provided in the middle plate body of the transfer plate, and the lower surface of the pressure cover in the middle opening is bonded with a hard rubber plate. A corner pad is bonded at four points on the inner shell surface of the magnetic switch shell below the transfer plate, and an inner groove is provided on the pad body of the corner pad. An inner sunken pad is bonded to the magnetic switch shell in the inner groove, and washers A and B are bonded in the magnetic switch shell between the inner sunken pad and the inner contact. An inner sunken disk is bonded to the magnetic switch shell inside the washers A and B.

[0007] Furthermore, the pad body thickness of the corner pad is greater than the pad body thickness of the inner-sunk pad; the corner pad and the inner-sunk pad can form a hierarchical buffer structure when the transfer plate is pressed downward.

[0008] Furthermore, the thickness of the inner sinking plate is smaller than the thickness of the rings of gasket A and gasket B; the inner sinking plate and gasket A can form a hierarchical buffer structure when the transfer plate is pressed down.

[0009] Furthermore, the hard rubber plate under the gland passes through the middle opening and presses on the surface of the inner contact; a hard rubber plate under the gland presses downward at the middle opening to touch the inner contact for triggering.

[0010] Furthermore, the plate body of the transfer plate is bonded to the lower surface of the pressure cover, and the four corners of the lower surface of the transfer plate are bonded to the corner pad; the plate body of the transfer plate can be bonded under the pressure cover for connection, and the transfer plate can be bonded and connected to the corner pad.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a buffering key structure between a magnetic switch shell equipped with an inner contact and a pressure cover. When the pressure cover is pressed toward the inner contact in the magnetic switch shell, a transfer plate, an angle pad, a gasket A and a gasket B are used between the two to buffer the initial pressure. When the inner sunken pad and the inner sunken plate continue to be pressed down at the pressure cover, a secondary buffer structure is formed to buffer the pressure contact noise of the pressure cover and the magnetic switch shell. The inner contact can be buffered when it is pressed by the hard rubber plate, thereby effectively reducing the noise when the magnetic switch contact key is pressed.
