Abstract

The invention discloses a magnetic suspension button and a keyboard. The magnetic suspension button is characterized by being provided with a key cap, a shaft sleeve plate, a capacitor circuit board with a built-in electrode group, a movable shaft core and a base plate from top to bottom in sequence. An upper end of the movable shaft core passes through the shaft sleeve plate and the movable shaft core is movablely buckled with the key cap. The magnetic suspension button is also provided with a magnetic suspension apparatus. The magnetic suspension apparatus comprises a magnet and an adsorption piece, wherein the magnet is arranged above the electrode group and is fixedly connected to a lower surface of the shaft sleeve plate, and the adsorption piece is arranged under the electrode group, oppositely arranged to the magnet and used for being attracted by the magnet. The adsorption piece is fixedly connected to the movable shaft core. The adsorption piece is a spring. The invention is advantaged by simple process, low production cost, stable stroke and touch, low friction, long service life, zero contact, small wear and good hand feeling.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a magnetic suspension key and a keyboard. Background technique [0002] According to the working principle and button mode of the keyboard, it can be divided into four types: 1. Mechanical keyboard, which uses a metal contact switch. The working principle is to make the contacts conduct or disconnect, and has the characteristics of strong hand feeling and loud noise. ;2. Conductive rubber keyboard, the structure of the contacts is connected by conductive rubber. There is a layer of raised conductive rubber inside the keyboard. Each key corresponds to a protrusion. When pressed, the contact below is connected. This type of keyboard is marketed by mechanical keyboard Transition to Membrane Keyboards product ; 3. Plastic film keyboard, the keyboard is divided into three layers, which realizes no mechanical wear, and is characterized by low price , low noise and low...
