What Is an Optical Axis?

The optical axis is an innovative micro-switch technology born on a traditional mechanical keyboard. By replacing the trigger metal paddle in the traditional mechanical axis switch structure with an infrared optical sensor component, the principle of light induction is used to generate different equivalent resistances. , Forming two states of open circuit and path, thereby triggering the key signal instruction. Due to the unidirectional transmission of optical signals, the input end and output end are completely electrically isolated. The keyboard and mouse peripheral products equipped with optical axis technology have strong anti-interference ability, stable work, no contact, and long service life.

The optical axis is an innovative micro-switch technology born on a traditional mechanical keyboard. By replacing the trigger metal paddle in the traditional mechanical axis switch structure with an infrared optical sensor component, the principle of light induction is used to generate different equivalent values.

Optically conductive mechanical switch (optical axis for short), using optical principles and optical coupling

The traditional mechanical keyboard is to meet the conditions of the operating force by pressing the switch in the direction of the switch. The switch function is closed and turned on. When the pressure is removed, the switch is opened. The internal structure of the mechanical keyboard is changed by the force of the metal shrapnel. When the shaft is not pressed down to the OP value, the switch contact is pushed open by the contact of the handle, and the switch is separated from the fixed contact, so the resistance is infinitely open. When the handle is pressed down to the OP value, the contact of the handle leaves the switch reed, and the contact resistance of the switch reed by the elastic force becomes very small to form a path, that is, a path is formed, and the mechanical shaft passes through the circuit. The on-off circuit of the stack makes on-off judgment to control the switch.

Traditional mechanical shafts rely on the spring force to separate the contacts of the lower fixed piece, so the resistance value is infinitely large to form an open circuit and a path.

Open path

1. Double-click, double-click, no response: After a long-term use of the traditional mechanical keyboard, the metal contact points will oxidize, even if the contacts are plated with gold or silver metal, which has a very slow oxidation rate. Oxidation will also occur under use, and the environment used by each mechanical keyboard is different. For example, gamers and Internet cafe users generally like smoking, drinking beer, drinking cola and so on. Therefore, the air is humid, and the high levels of sulfide and acid in the air directly aggravate the oxidation and blackening of the metal contact points, which causes problems such as double-clicking, double-clicking, and non-responsiveness of the keyboard.

2. Feeling worse: Under long-term use of the keyboard and repeated pressing and stroking, the spring appears fatigued, resulting in poor feel, astringency or weak rebound, etc., and the lower cover guide groove. If the guide post is too small and the wear is too large, it will easily cause the button to loosen, which will affect the feel of the button. . ^[1-3]

The optical axis has certain advantages over traditional mechanical axis switches, such as: optical induction, no contact, zero wear, no noise, billion times of pressing, etc. These are based on the improvement and innovation of traditional mechanical keyboard switches. ^[1-3]

Optical axis switch application

Today, optical axis mechanical switches are widely used in the field of electronic technology, but their application in the competitive peripheral industry is still blank. Therefore, the damage of the keyboard and mouse is serious, the service life is short, and the maintenance cost is high, which brings many disadvantages to consumers.

Optical axis technology fills the blank of keyboard micro-switches in the field of peripherals, and eliminates many disadvantages brought by ordinary mechanical axes, making peripheral products reborn: super fast response, super smooth feel, zero signal noise, high use life.

Optical axis mechanical keyboard has exquisite workmanship and full scale

-Inch keyboard design, so that the keyboard has a good appearance and visual effects. Full key non-conflict and 1000Hz USB reporting rate make the keyboard accurately respond to every player's tap. In addition, the keyboard is also equipped with a USB interface and an audio interface, which can meet more connection needs. ^[1-3]
