Abstract

The invention provides a key and a keyboard. The key comprises a keycap, a moving member, an elastic member, a circuit board and a proximity switch. The moving member is disposed below the keycap and connected with the elastic member. When the keycap drives the moving member to move down, the elastic member is loaded. The circuit board is disposed below the moving member. The proximity switch comprises a to-be-detected member disposed on the moving member and a displacement sensing switch disposed on the circuit board. When the keycap drives the moving member to move to the displacement sensing switch and arrive in a detectable range, the displacement sensing switch is closed. The keyboard comprises a plurality of the keys; the keys are disposed on the same circuit board. The key and the keyboard have the advantages that the to-be-detected member and the displacement sensing switch are split, no contact occurs during execution of key commands, and the technical problem that during key pressing, repeated friction of the moving members and electrical connections shortens lives of the electrical connections can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of computer hardware equipment, in particular to a button and a keyboard. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's living standards, computers have become electronic devices that are often used in daily office and life. As an indispensable hardware device in computer use, keyboard plays a vital role in computer input. Multiple keys are set on the keyboard, and the user can input English letters, numbers, punctuation marks, etc. into the computer by tapping the corresponding keys, so as to issue commands to the computer. [0003] The keys of existing keyboards include electrical contacts, springs and movable parts. Usually, the number of electrical contacts is two, and the movable parts are made of insulating materials; when the keys are pressed, the springs are compressed, and the movable parts move downward, making The tw...
